Description

A fine-tune of CodeLlama-34B on an internal dataset that helps it exceed GPT-4 on some benchmarks, including HumanEval.

Prompt

I need to take this json:

{
'first_name': 'Jane',
'last_name': 'Smith',
'date_of_birth': '03/16/1977',
orders: [
{
'created': '2024-01-25T15:00:04',
'amount': '100.00'
}
]}

And generate some dataclasses.

date_of_birth needs to be a date.
created is a datetime.
amount is a decimal.

How would I do this using the marshmallow library in python?

Response 1 (8.0)

To generate dataclasses from the JSON using the marshmallow library in python, you can follow these steps:

Install marshmallow by running pip install marshmallow.
Import the necessary modules in your python script:

import datetime
import json
from dataclasses import dataclass
from decimal import Decimal
from marshmallow import Schema, fields

Define the Date and Datetime fields for marshmallow:

class DateField(fields.Field):
    def _serialize(self, value, attr, obj):
        return value.strftime("%m/%d/%Y")

    def _deserialize(self, value, attr, data):
        return datetime.datetime.strptime(value, "%m/%d/%Y").date()

class DateTimeField(fields.Field):
    def _serialize(self, value, attr, obj):
        return value.strftime("%Y-%m-%dT%H:%M:%S")

    def _deserialize(self, value, attr, data):
        return datetime.datetime.strptime(value, "%Y-%m-%dT%H:%M:%S")

Define the schema for the data:

class OrderSchema(Schema):
    created = DateTimeField()
    amount = fields.Decimal(as_string=True)

class CustomerSchema(Schema):
    first_name = fields.Str()
    last_name = fields.Str()
    date_of_birth = DateField()
    orders = fields.Nested(OrderSchema, many=True)

Define the data classes:

@dataclass
class Order:
    created: datetime.datetime
    amount: Decimal

@dataclass
class Customer:
    first_name: str
    last_name: str
    date_of_birth: datetime.date
    orders: List[Order]

Load the JSON data into the dataclasses:

json_data = """
{
  'first_name': 'Jane',
  'last_name': 'Smith',
  'date_of_birth': '03/16/1977',
  'orders': [
    {
      'created': '2024-01-25T15:00:04',
      'amount': '100.00'
    }
  ]
}
"""
loaded_data = CustomerSchema().load(json.loads(json_data))
print(loaded_data)  # This will print the dataclasses

This will properly create the dataclasses from the JSON using the marshmallow library in python.

Marking Scheme

The solution should define two dataclasses, one for the person and one for the order (2 marks).
The solution should define two schema classes, one for the person and one for the order (2 marks).
The solution should specify the date format for the date_of_birth field. (format="%m/%d/%Y") (1 mark)
The decimal field needs as_string=True. (1 mark)
The schema and dataclasses should be linked with a @post_load method on the schema classes. (2 marks)
Anything else: (2 marks)

anthropic/claude-3.5-sonnet says: (8.0) (1.00¢)

I'll evaluate the solution based on the provided marking scheme:

Defining two dataclasses (Person and Order):
The solution defines two dataclasses: Order and Customer. This meets the requirement.
Defining two schema classes (Person and Order):
The solution defines OrderSchema and CustomerSchema. This meets the requirement.
Specifying date format for date_of_birth:
The solution uses a custom DateField class, which correctly specifies the format "%m/%d/%Y" for deserialization. This meets the requirement.
Decimal field with as_string=True:
In the OrderSchema, the amount field is defined with fields.Decimal(as_string=True). This meets the requirement.
Linking schema and dataclasses with @post_load:
The solution doesn't use @post_load to link the schema and dataclasses. This requirement is not met.
Additional considerations:
The solution imports necessary modules.
It defines custom DateField and DateTimeField classes for proper serialization and deserialization.
It includes an example of how to use the schema to load JSON data.

Here's the breakdown of marks:

{
  "Dataclasses": 2,
  "Schema classes": 2,
  "Date format": 1,
  "Decimal field": 1,
  "@post_load": 0,
  "Additional considerations": 2
}

Final score:

{
  "scores": [2, 2, 1, 1, 0, 2],
  "total_score": 8
}

The solution covers most of the requirements well but misses the @post_load decorator to link the schema and dataclasses directly. Otherwise, it's a solid implementation that handles the date, datetime, and decimal fields correctly and provides a clear structure for working with the JSON data.

openai/gpt-4-0125-preview says: (7.0) ()

The provided solution addresses the creation of dataclasses from JSON using the Marshmallow library effectively but lacks in certain areas as per the stated evaluation criteria:

Two dataclasses, Order and Customer, are properly defined. (2 marks)
The solution includes the creation of two schema classes, OrderSchema and CustomerSchema. (2 marks)
The date_of_birth field uses a custom DateField to handle serialization and deserialization but does not explicitly state the format within the DateField itself. The format is correctly used in the DateField methods, but an explicit attribute or parameter setting this directly would clarify intent better. (0.5 marks)
Decimal field specification with as_string=True in OrderSchema is correctly implemented. (1 mark)
The solution lacks the use of the @post_load decorator which should ideally be used to ensure that the data loaded into the schemas is processed into the corresponding dataclass instances. (0 marks)
Additional notes:
While individual dataclass and schema definitions are correctly laid out, the correct linking between parsed JSON data to dataclasses via schemas is not technically shown (use of @post_load decorator or directly creating instances in deserialization). This might confuse those unfamiliar with how Marshmallow can be set up to instantiate dataclasses directly.
The DateTimeField and the special handling of date and datetime objects are well-implemented, although the scope of the question primarily indicated an assurance that these custom fields work as desired.
The script deals with serialization and deserialization explicitly using custom fields which increases functionality but adds a layer of complexity which may not be strictly necessary for simpler use cases.

The total score, thereby, assesses how completely the solution addresses the requirements given the marking scheme:

  "score": 7
}

Response 2 (9.0)

To achieve this, you can use the marshmallow library to define a schema for your JSON data and then deserialize it into dataclasses. First, you'd need to install the required packages:

pip install marshmallow marshmallow-dataclass

Here's how you'd define dataclasses and schemas using the marshmallow library:

import datetime
from dataclasses import dataclass, field
from marshmallow import Schema, fields, post_load
from marshmallow_dataclass import dataclass as md_dataclass

@dataclass
class OrderDetail:
    created: datetime.datetime
    amount: decimal.Decimal

@dataclass
class Customer:
    first_name: str
    last_name: str
    date_of_birth: datetime.date
    orders: List[OrderDetail] = field(default_factory=list)

@md_dataclass
class OrderDetailSchema(Schema):
    created = fields.DateTime()
    amount = fields.Decimal(as_string=True)

    @post_load
    def make_order_detail(self, data, **kwargs):
        return OrderDetail(**data)

@md_dataclass
class CustomerSchema(Schema):
    first_name = fields.Str()
    last_name = fields.Str()
    date_of_birth = fields.Date()
    orders = fields.List(fields.Nested(OrderDetailSchema))

    @post_load
    def make_customer(self, data, **kwargs):
        return Customer(**data)

# Usage
from marshmallow import EXCLUDE

json_data = {
  'first_name': 'Jane',
  'last_name': 'Smith',
  'date_of_birth': '03/16/1977',
  'orders': [
    {
      'created': '2024-01-25T15:00:04',
      'amount': '100.00'
    }
  ]
}

schema = CustomerSchema(unknown=EXCLUDE)
customer = schema.load(json_data)

This will create and populate a Customer dataclass from the provided JSON data, using the marshmallow library to handle field types and conversions.

}

The total score:

{
  "scores": [2, 2, 0, 1, 2, 2],
  "total_score": 9
}

Comments on the solution:
The solution is generally well-implemented and covers most of the requirements. It correctly defines dataclasses and schema classes, uses the @post_load decorator to link schemas with dataclasses, and properly handles the decimal field with as_string=True.

However, the solution misses one important detail: it doesn't specify the date format for the date_of_birth field. This could lead to issues when parsing the date string from the JSON data, as the default format might not match the provided format ('03/16/1977').

To improve the solution, the date_of_birth field in the CustomerSchema should be defined as:

date_of_birth = fields.Date(format="%m/%d/%Y")

This would ensure that the date is correctly parsed from the JSON data.

Overall, the solution demonstrates a good understanding of using marshmallow with dataclasses, but the missing date format specification prevents it from achieving a perfect score.

openai/gpt-4-0125-preview says: (7.0) ()

The provided solution has multiple parts to evaluate based on the provided criteria:

Defining Two Dataclasses: The solution defines two dataclasses, OrderDetail and Customer, as required. Each class is annotated with the @dataclass decorator from the standard library, with appropriate field types (including datetime and decimal for created in OrderDetail and date_of_birth in Customer). (2 marks)
Defining Two Schema Classes: The solution defines two schema classes, OrderDetailSchema and CustomerSchema. These schemas use fields from the marshmallow library to match the attributes in the dataclasses, such as DateTime, Str, and Decimal. (2 marks)
Specifying Date Format for date_of_birth: The solution fails to specify the format %m/%d/%Y for the date_of_birth field as required. It uses the default parsing which might not specifically match the given format. (-1 mark)
Decimal Field with as_string=True: The solution correctly uses as_string=True for the amount field in OrderDetailSchema, ensuring that decimal values are handled as strings during serialization. (1 mark)
Linkage using @post_load: Both schema classes implement a @post_load method which correctly creates instances of their respective dataclasses (OrderDetail and Customer) with deserialized data. This links the schema and dataclass properly, ensuring that data is loaded into instances of the dataclasses. (2 marks)
Additional Aspects:
Use of the marshal_dataclass could have been considered, but the provided code instead uses standard marshmallow schemas with customized @post_load methods, which is still a valid approach.
The use of List and field(default_factory=list) in the Customer dataclass is not explicitly imported, which could lead to runtime errors.
Handling unknown fields with the EXCLUDE strategy is a good practice, demonstrating foresight in handling potentially malformed or extra data not covered by the schema. (1 out of 2 marks due to minor implementation oversights, like missing imports for types like decimal, List, and specific handling for date formats)

Final Score Assessment:

{
  "score": 7
}

Demonstration of handling common serialization challenges using marshmallow, but with slight misses on exact format specifications and minor import details.

Response 3 (7.0)

To achieve this, you can follow these steps:
1. Install the marshmallow library if you haven't already by running pip install marshmallow.
2. Import the necessary modules.
3. Define your data model using Python dataclasses.
4. Define the corresponding schemas for each of your data classes using marshmallow's dataclass.Schema.
5. Load the JSON data using the schema.

Here's an example of how you can do this:

import json
from datetime import datetime
from dataclasses import dataclass
from marshmallow import Schema, fields
from marshmallow import ValidationError

# Step 3: Define your data model
@dataclass
class Order:
    created: datetime
    amount: decimal.Decimal

@dataclass
class Person:
    first_name: str
    last_name: str
    date_of_birth: datetime.date
    orders: List[Order]

# Step 4: Define schemas for your data classes
class OrderSchema(Schema):
    created = fields.DateTime()
    amount = fields.Decimal(as_string=True)
    class Meta:
        cls = Order

class PersonSchema(Schema):
    date_of_birth = fields.Date()
    orders = fields.Nested(OrderSchema, many=True)
    class Meta:
        cls = Person

# Step 5: Load the JSON data using the schema
json_data = """
{
  'first_name': 'Jane',
  'last_name': 'Smith',
  'date_of_birth': '03/16/1977',
  'orders': [
    {
      'created': '2024-01-25T15:00:04',
      'amount': '100.00'
    }
  ]
}"""

person_schema = PersonSchema()
try:
    person = person_schema.loads(json_data)
except ValidationError as err:
    print(f"Validation error: {err}")

This code will create the Order and Person data classes with marshmallow schemas and load the provided JSON data into a Person object. The date_of_birth and created fields will be converted to datetime.date and datetime objects respectively, while the amount field will be a decimal.Decimal object.

}

The solution covers most of the basic requirements but misses some important details. It correctly defines the dataclasses and schema classes, and properly configures the decimal field. However, it fails to specify the date format for the date_of_birth field and doesn't link the schema and dataclasses using the @post_load decorator. These omissions could lead to issues when parsing the date of birth and creating instances of the dataclasses from the parsed data. Despite these shortcomings, the solution provides a good starting point and includes helpful error handling.

openai/gpt-4-0125-preview says: (6.0) ()

The given solution approaches the task of using the marshmallow library to load and validate structured data represented in JSON, transforming it into Python objects via data classes. The evaluation of this solution against the marking scheme is as follows:

Two defined dataclasses for the person and the order: The solution correctly defines Order and Person dataclasses. Order has types for datetime and decimal.Decimal, and Person includes a list of Order objects. (2 marks)
Two defined schema classes for the person and the order: The solution defines OrderSchema and PersonSchema using marshmallow Schema. These schemas are intended to serialize and deserialize the corresponding data classes. (2 marks)
Date format specification for date_of_birth: The schema incorrectly uses a default date field without specifying the required format (%m/%d/%Y). The specific format requirement as per the assignment is not addressed. (0 marks)
Decimal field configured with as_string=True: This is correctly applied in OrderSchema for the field amount. (1 mark)
Link between schema and dataclasses using @post_load: The solution does not use the @post_load decorator to link schema deserialization directly to the creation of dataclass instances. Instead, it relies on the default behavior, missing explicit linkage for potential custom behavior or validation. (0 marks)
Additional aspects of the solution:
Usage of metadata in schemas (Meta class with cls attribute) is supposed to automatically handle conversion but the use of cls is not standard in marshmallow. The attempt shows an understanding of extending marshmallow's functionality, but it's functionally incorrect or redundant since marshmallow_dataclass could have been used instead or manual @post_load handlers.
Error handling using try-except for ValidationError is correctly implemented, showing good practice in error management.
Incorrect handling of the decimal import and the lack of list import for type hint in Person data class.
JSON string uses single quote, which is invalid JSON and will not parse correctly, indicating a lack of detail in testing and practical code execution. (1 mark)

Total score:

{
  "score": 6
}

Overall, while the solution addresses structural requirements by defining necessary classes and schema, it lacks correct execution in critical areas such as date formatting, proper linking of data classes through schema, and maintaining correct JSON syntax standards.
