Virtual Apps¶

This module facilitates the ingestion and evaluation of application logs that were generated outside of TruLens. It allows for the creation of a virtual representation of your application, enabling the evaluation of logged data within the TruLens framework.

To begin, construct a virtual application representation. This can be achieved through a simple dictionary or by utilizing the VirtualApp class, which allows for a more structured approach to storing application information relevant for feedback evaluation.

Constructing a Virtual Application

virtual_app = {
    'llm': {'modelname': 'some llm component model name'},
    'template': 'information about the template used in the app',
    'debug': 'optional fields for additional debugging information'
}
# Converting the dictionary to a VirtualApp instance
from trulens.core import Select
from trulens.apps.virtual import VirtualApp

virtual_app = VirtualApp(virtual_app)
virtual_app[Select.RecordCalls.llm.maxtokens] = 1024

Incorporate components into the virtual app for evaluation by utilizing the Select class. This approach allows for the reuse of setup configurations when defining feedback functions.

Incorporating Components into the Virtual App

# Setting up a virtual app with a retriever component
from trulens.core import Select
retriever_component = Select.RecordCalls.retriever
virtual_app[retriever_component] = 'this is the retriever component'

With your virtual app configured, it's ready to store logged data. VirtualRecord offers a structured way to build records from your data for ingestion into TruLens, distinguishing itself from direct Record creation by specifying calls through selectors.

Below is an example of adding records for a context retrieval component, emphasizing that only the data intended for tracking or evaluation needs to be provided.

Adding Records for a Context Retrieval Component

from trulens.apps.virtual import VirtualRecord

# Selector for the context retrieval component's `get_context` call
context_call = retriever_component.get_context

# Creating virtual records
rec1 = VirtualRecord(
    main_input='Where is Germany?',
    main_output='Germany is in Europe',
    calls={
        context_call: {
            'args': ['Where is Germany?'],
            'rets': ['Germany is a country located in Europe.']
        }
    }
)
rec2 = VirtualRecord(
    main_input='Where is Germany?',
    main_output='Poland is in Europe',
    calls={
        context_call: {
            'args': ['Where is Germany?'],
            'rets': ['Poland is a country located in Europe.']
        }
    }
)

data = [rec1, rec2]

For existing datasets, such as a dataframe of prompts, contexts, and responses, iterate through the dataframe to create virtual records for each entry.

Creating Virtual Records from a DataFrame

import pandas as pd

# Example dataframe
data = {
    'prompt': ['Where is Germany?', 'What is the capital of France?'],
    'response': ['Germany is in Europe', 'The capital of France is Paris'],
    'context': [
        'Germany is a country located in Europe.',
        'France is a country in Europe and its capital is Paris.'
    ]
}
df = pd.DataFrame(data)

# Ingesting data from the dataframe into virtual records
data_dict = df.to_dict('records')
data = []

for record in data_dict:
    rec = VirtualRecord(
        main_input=record['prompt'],
        main_output=record['response'],
        calls={
            context_call: {
                'args': [record['prompt']],
                'rets': [record['context']]
            }
        }
    )
    data.append(rec)

After constructing the virtual records, feedback functions can be developed in the same manner as with non-virtual applications, using the newly added context_call selector for reference. The same process can be repeated for any additional selector you add.

Developing Feedback Functions

from trulens.providers.openai import OpenAI
from trulens.core.feedback.feedback import Feedback

# Initializing the feedback provider
openai = OpenAI()

# Defining the context for feedback using the virtual `get_context` call
context = context_call.rets[:]

# Creating a feedback function for context relevance
f_context_relevance = Feedback(openai.context_relevance).on_input().on(context)

These feedback functions are then integrated into TruVirtual to construct the recorder, which can handle most configurations applicable to non-virtual apps.

Integrating Feedback Functions into TruVirtual

from trulens.apps.virtual import TruVirtual

# Setting up the virtual recorder
virtual_recorder = TruVirtual(
    app_name='a virtual app',
    app_version='base',
    app=virtual_app,
    feedbacks=[f_context_relevance]
)

To process the records and run any feedback functions associated with the recorder, use the add_record method.

Example: "Logging records and running feedback functions"

```python
# Ingesting records into the virtual recorder
for record in data:
    virtual_recorder.add_record(record)
```

Metadata about your application can also be included in the VirtualApp for evaluation purposes, offering a flexible way to store additional information about the components of an LLM app.

Storing metadata in a VirtualApp

# Example of storing metadata in a VirtualApp
virtual_app = {
    'llm': {'modelname': 'some llm component model name'},
    'template': 'information about the template used in the app',
    'debug': 'optional debugging information'
}

from trulens.core import Select
from trulens.apps.virtual import VirtualApp

virtual_app = VirtualApp(virtual_app)
virtual_app[Select.RecordCalls.llm.maxtokens] = 1024

This approach is particularly beneficial for evaluating the components of an LLM app.

Evaluating components of an LLM application

# Adding a retriever component to the virtual app
retriever_component = Select.RecordCalls.retriever
virtual_app[retriever_component] = 'this is the retriever component'

layout_calls_as_app() -> Munch

Layout the calls in this record into the structure that follows that of the app that created this record.

This uses the paths stored in each RecordAppCall which are paths into the app.

Note: We cannot create a validated AppDefinition class (or subclass) object here as the layout of records differ in these ways:

Records do not include anything that is not an instrumented method hence have most of the structure of a app missing.
Records have RecordAppCall as their leafs where method definitions would be in the AppDefinition structure.

TruVirtual ¶

Bases: App

Recorder for virtual apps.

Virtual apps are data only in that they cannot be executed but for whom previously-computed results can be added using add_record. The VirtualRecord class may be useful for creating records for this. Fields used by non-virtual apps can be specified here, notably:

See App and AppDefinition for constructor arguments.

The `app` field.¶

You can store any information you would like by passing in a dictionary to TruVirtual in the app field. This may involve an index of components or versions, or anything else. You can refer to these values for evaluating feedback.

Usage

You can use VirtualApp to create the app structure or a plain dictionary. Using VirtualApp lets you use Selectors to define components:

virtual_app = VirtualApp()
virtual_app[Select.RecordCalls.llm.maxtokens] = 1024

Example

virtual_app = dict(
    llm=dict(
        modelname="some llm component model name"
    ),
    template="information about the template I used in my app",
    debug="all of these fields are completely optional"
