Cloud or Self Hosted

Self Hosted (Docker)

Steps to reproduce

1.I successfully imported the third-party Python library 'mysql-connector-python' into the sandbox container, and the execution of 'import mysql.connector' was successful.

2.However, when executing the script in the web interface, the prompt states 'in ModuleNotFoundError: No module named 'mysql' error'

'dify-api' and 'sandbox' are network-connected, and the corresponding .py files will be generated within the sandbox container.

✔️ Expected Behavior

No response

❌ Actual Behavior

No response

To address the issue where the 'mysql-connector-python' library works in your Python sandbox container but not through the web interface, ensure the library is installed in the correct environment used by Dify for executing Python scripts. Here's a focused approach:

Custom Docker Image: Modify the Docker Compose configuration for the sandbox service to use a custom Docker image that includes 'mysql-connector-python'. This ensures the library is available for scripts executed via the web interface.
Dependency Installation Script: If Dify allows initializing the sandbox with a script, use it to install 'mysql-connector-python' before running your main script.
Refresh Python Environment: Use the post_start_command.sh script to update the Python environment within Dify, ensuring all dependencies, including 'mysql-connector-python', are correctly installed.
Consult Dify Documentation or Support: For detailed guidance on managing Python dependencies within the sandbox, refer to the latest Dify documentation or contact their support.

By ensuring 'mysql-connector-python' is accessible in the sandbox environment where Dify executes Python scripts, the ModuleNotFoundError should be resolved, allowing your scripts to run as expected.

@dosubot I would like to inquire about how 'code execution' occurs within the sandbox container. I have noticed that the 'dify-sandbox' container comes with the Python library 'request' pre-installed, yet it still cannot be imported.

May 17 '24 06:05 115341chenzehao

To resolve the issue with the 'requests' library not being imported in your Dify sandbox environment, despite it being pre-installed, you should ensure that your project is correctly set up to install external libraries. Here's a concise guide:

Create or Update requirements.txt: In the api directory of your project, ensure there's a requirements.txt file listing requests and any other libraries you need. Format it like so:
```
requests==2.25.1
```
Check Project Structure: The requirements.txt should be in an api directory at your project's root.
Restart Dify Sandbox: Deploy your project or restart the sandbox. The post_start_command.sh script will run pip install -r requirements.txt, installing the specified libraries.
Test Library Installation: After restarting, test the requests library with a simple script to confirm it's working as expected.

This approach leverages Dify's mechanism for handling external libraries via a requirements.txt file, ensuring your scripts can use requests within the sandbox. If issues persist, ensure your project aligns with Dify's guidelines on allowed operations and library usage, as recent updates restrict certain activities. For more detailed guidance, refer to the Dify documentation and the post_start_command.sh script.

I am also failing to call the Flask dependency from the requirements.txt file during 'code execution'

May 17 '24 07:05 115341chenzehao

To address the issue with importing requests and Flask from your requirements.txt in the Dify sandbox environment, follow these targeted steps:

Ensure Correct Location: Confirm that your requirements.txt is correctly placed in the api directory and lists both requests and Flask.
Virtual Environments: If Dify uses a Python virtual environment, make sure the pip install command executes within this environment to avoid scope issues.
Review post_start_command.sh Output: Check this script's output for errors during the installation process, which could highlight the root cause.
Manual Installation Check: Attempt to manually run pip install -r requirements.txt in the same context as the post_start_command.sh script to identify any discrepancies.
Python Version Compatibility: Verify that the Python version in your sandbox supports the requests and Flask versions you're trying to install.
Permissions: Ensure the script has the necessary permissions to install packages, possibly requiring adjustments for elevated privileges.
Dependencies: Consider any unmet dependencies that pip might not resolve automatically, although this is less common.

Remember, the Dify sandbox has specific restrictions, especially regarding Python virtual environments and external package installations, due to its secure execution model. If these steps do not resolve your issue, consulting the Dify documentation or support for sandbox-specific guidance might provide further insights.

I want to check the source code of "dify-sandbox", can you provide it?

May 20 '24 10:05 115341chenzehao

To address the issue with libraries not being imported in your Dify sandbox environment, first ensure that mysql-connector-python and requests are correctly listed in your requirements.txt file, including specifying the versions if necessary. For example:

mysql-connector-python==8.0.23
requests==2.25.1

After updating requirements.txt, rebuild the container to install these dependencies. If you're still facing issues, manually install them inside the container for testing:

pip install mysql-connector-python requests

This can help identify any potential errors not related to the requirements.txt file. Also, check the permissions and ensure the pip version inside the container is up to date to avoid installation issues.

Regarding accessing the "dify-sandbox" source code, since Dify is open-source, the code should be available on their official GitHub or GitLab repository. If you can't find it, consult the project's documentation or contact the maintainers for guidance.

Keep in mind, Dify's sandbox environment has limitations, such as restricted file system access, network calls, and operating system-level commands, which might lead to ModuleNotFoundError for some modules.

I tried to successfully install mysql-connector-python in the sandbox container, but when "code_executor" ran the py script, import mysql.connector prompted ModuleNotFoundError, so I wanted to take a look at the source code of "dify-sandbox". I found it on dify's github. I haven't found the sandbox information. Can you help me consult?

May 21 '24 01:05 115341chenzehao

The source code for "dify-sandbox" can be found by cloning the Dify repository from GitHub. You can do this using the following command:

git clone https://github.com/langgenius/dify.git

This repository contains the source code for the Dify project, including the "dify-sandbox" service. For more detailed instructions on setting up and deploying the project, you can refer to the documentation provided in the repository.

For specific details about the sandbox service, you can check the docker-compose.yaml and docker-compose.middleware.yaml files, which include configurations for the sandbox environment. Here are the relevant links:

These files will give you insights into how the sandbox is set up, including environment variables, volumes, and network configurations. This should help you understand why the ModuleNotFoundError for mysql.connector is occurring and how to resolve it.

@takatost, could you help with this?

First discovery, Dify automatically adds some pre import lines for every executed code that looks like this:

# YOUR CODE FROM HERE

If I specify some libraries in the GUI via "ADVANCED DEPENDENCIES" then it will just add an import line in the precode, as you can see above with ìmport beautifulsoup4

First problem: BeautifulSoup is a great example as the import should be handled with this line from bs4 import BeautifulSoup and not import beautifulsoup4 so this implementation might cause problem if the name of the dependency is not the name that should be used to import it.

Second problem (main problem of the GitHub Issue): So i decided to not use the GUI ADVANCED DEPENDENCIES dropdown menu and instead write manually my imports in the code. But even after writing the correct from bs4 import BeautifulSoup I get:

But running the code directly from the terminal does work:

# python /tmp/code/d284b100_93dc_4832_852c_56e48a0cdc15.py
{'result': {'pages': {'...................................'}}}

So What does the ADVANCED DEPENDENCIES dropdown menu do more that just to add some pre-lines before the code that makes the code run correctly.

What does this litteraly change if requests is written (see comments below):

# cat /tmp/code/01b318a6_8b12_4374_9ae1_a1011ac41648.py
import ctypes

    sys.exit(-1)

sys.excepthook = excepthook

lib = ctypes.CDLL("./tmp/sandbox-python/python.so")
lib.DifySeccomp.argtypes = [ctypes.c_uint32, ctypes.c_uint32, ctypes.c_bool]

I agree, the ability to add dependencies in the execution sandbox would be very helpful.

@thibaudbrg which /dependencies/python-requirements.txt did you change? I am not able to find the Dockerfile for the execution sandbox, this makes it hard to reason about how to actually change anything.

Jun 21 '24 07:06 mai-group-labs

@mai-group-labs on the sandbox container. This is the container used for python execution.

docker exec -it sandbox_container_name /bin/sh

And every python code you write are located /temp/code/.

Also you can access the file /dependencies/python_requirements.txt from the same container. But it is easier to directly bind the /dependencies/ folder as a volume in the sandbox docker compose:

volumes:
      - ./volumes/sandbox/dependencies:/dependencies

I upgraded to sandbox container 0.2.1 but didn't tried if the problem was solved. It'd be nice to have an answer from someone involved at Dify.

Jul 27 '24 02:07 jerryleooo

The same problem occurs when importing beautifulsoup4. As @thibaudbrg analyzed, the way to import dependent libraries is confusing. To sum up, there are two questions:

Since selecting a dependent library in the "Advanced Dependencies" drop-down menu only adds a line of "import ..." when generating a .py file, why is it invalid to just add a line of "import ..." in the code block, and you must select the dependent library in the "Advanced Dependencies" drop-down menu?
If you must select a dependent library in the "Advanced Dependencies" drop-down menu, it only supports the form of "import requests", but cannot support forms such as "from bs4 import BeautifulSoup", which is really not flexible enough.

This problem does not occur at all in normal Python programming. I don't understand why an "advanced dependency" mechanism should be introduced. Instead, it complicates the problem, but I don't see any benefits.

Aug 10 '24 13:08 NKfairyland

@dosubot I would like to inquire about how 'code execution' occurs within the sandbox container. I have noticed that the 'dify-sandbox' container comes with the Python library 'request' pre-installed, yet it still cannot be imported.

The requests library can be imported. You need to add an item in "Advanced Dependencies" and select "requests" in the drop-down menu. However, the beautifulsoup4 library cannot be imported in the same way, because the correct format is "from bs4 import BeautifulSoup", not "import beautifulsoup4".
