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.

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 handle removing extra leading/trailing quotes in the output of the if module_end_str.strip("'\"") != module_end_str:
# if there's leading/trailing quotes, then we need to eval
# string to get the actual expression
module_end_str = safe_eval(module_end_str, {"np": np}, local_vars)This code checks if the string with leading/trailing quotes removed is different from the original string. If it is, it evaluates the string to get the actual expression. This ensures that any unnecessary quotes are removed before further processing. Additionally, the Moreover, the DEFAULT_INSTRUCTION_STR = (
"1. Convert the query to executable Python code using Pandas.\n"
"2. The final line of code should be a Python expression that can be called with the `eval()` function.\n"
"3. The code should represent a solution to the query.\n"
"4. PRINT ONLY THE EXPRESSION.\n"
"5. Do not quote the expression.\n"
)This ensures that the generated Python code does not include unnecessary quotes that could cause syntax errors or other issues [1][2][3]. |

The 1. Ensure Correct Instruction StringThe instruction string guides the language model to generate proper Python code. Ensure that the instruction string is correctly set to avoid unnecessary inclusions like 'python' and to generate clean, executable code. DEFAULT_INSTRUCTION_STR = (
