Hey there, @toaster9996! 👋 I'm Dosu, your friendly neighborhood bot here to assist with bugs, answer your questions, and guide you through contributing while we wait for a human to chime in. I'm here to help, so let's crack this issue together! I'll be diving into your Seaborn graphing problem and get back to you with some insights shortly. Stay tuned! 🤖🔍 |
|
I'm not sure what you mean by using the llm to graph, but this error is raised in the pandas query engine when the generated pandas code is unsafe to execute |
|
To address the
The issue is less about Seaborn itself and more about how the code is structured or executed within the LLM's security model. Adjust your approach to align with the allowed practices for importing and using libraries, and ensure your code does not violate the security constraints in place. This might involve revising how you dynamically generate or execute code, especially if it involves patterns that are not permitted.
|
Why would being able to call a Python library be considered unsafe to execute, if the related library (seaborn) is in the allowed import list? |
|
@dosu._ How to use safe importing? |
|
To safely import and use Seaborn within your restricted execution environment, you'll need to follow the specific guidelines provided by the environment for safe importing. This typically involves using a designated function, often named something like Here's a concise guide on how to proceed:
By adhering to these steps, you can import and utilize Seaborn for your graphing needs within the security constraints of your execution environment, thus avoiding errors related to unsafe code execution.

@dosu._ how to use _restricted_import('seaborn') and saved in your enivronment? |
|
To use
This approach ensures that Seaborn is imported safely according to the security and import restrictions of your environment.
|
|
@dosu._ after importing the library using seaborn = _restricted_import('seaborn') code, still provides the same RunTimeError (RuntimeError: Execution of code containing references to private or dunder methods, disallowed builtins, or any imports, is forbidden!) How to enable the use of imported libraries? |
|
To enable the use of Seaborn or any other imported libraries in a restricted execution environment without encountering the
This method ensures that Seaborn is imported and used within the guidelines of the restricted execution environment, mitigating the risk of triggering runtime errors related to security constraints.
|
|
@dosu._ Setting up the libraries with _restricted_import and using safe_exec, still returns the error: RuntimeError: Execution of code containing references to private or dunder methods, disallowed builtins, or any imports, is forbidden! |
|
To address the
By carefully reviewing and adjusting your code according to these guidelines, you should be able to mitigate the issue and successfully use Seaborn within the constraints of your restricted execution environment.

To configure the Step 1: Set Up the DataFrame and Query EngineLoad your DataFrame and initialize the import pandas as pd
from llama_index.experimental.query_engine.pandas import PandasQueryEngine
# Load your DataFrame
df = pd.DataFrame(
{
"city": ["Toronto", "Tokyo", "Berlin"],
"population": [2930000, 13960000, 3645000],
}
)
# Initialize the PandasQueryEngine
query_engine = PandasQueryEngine(df=df, verbose=True)Step 2: Query the DataFrameUse the response = query_engine.query(
"What is the city with the highest population?",
)Step 3: Display the ResultsUse the from IPython.display import Markdown, display
display(Markdown(f"<b>{response}</b>"))Step 4: Retrieve and Print the Pandas InstructionsTo ensure proper syntax and avoid synthesized responses, you can print the Pandas instructions generated by the engine. print(response.metadata["pandas_instruction_str"])Step 5: Customize Prompts (Optional)If you need to modify the prompts for more detailed analysis, you can update the prompts as shown below. from llama_index.core.prompts import PromptTemplate
new_prompt = PromptTemplate(
"""\
You are working with a pandas dataframe in Python.
The name of the dataframe is `df`.
This is the result of `print(df.head())`:

Follow these instructions:
{instruction_str}
Query: {query_str}
Expression: """
)
query_engine.update_prompts({"pandas_prompt": new_prompt})Step 6: Disable Response SynthesisEnsure that the query_engine = PandasQueryEngine(df=df, verbose=True, synthesize_response=False)By following these steps, you can configure the Example UsageHere’s a complete example: import pandas as pd
from llama_index.experimental.query_engine.pandas import PandasQueryEngine
from IPython.display import Markdown, display
# Load your DataFrame
df = pd.DataFrame(
{
"city": ["Toronto", "Tokyo", "Berlin"],

}
)
# Initialize the PandasQueryEngine
query_engine = PandasQueryEngine(df=df, verbose=True, synthesize_response=False)
# Perform a query
response = query_engine.query("What is the city with the highest population?")
# Display the results
display(Markdown(f"<b>{response}</b>"))
# Print the Pandas instructions
print(response.metadata["pandas_instruction_str"])This setup ensures that the |
