  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

Assistant: The error message you are encountering indicates an issue with the configuration of the `setup.py` file used for the installation of the package (most likely the `gym` package based on the error details). The problem is related to incorrect options specified in the `setup.py` configuration. Here's a breakdown and some potential solutions:

1. **Unknown Distribution Option: 'tests_require'**:
    - As the warning suggests, `tests_require` is an unrecognized option. This may happen if you are using a newer version of `setuptools`, which no longer supports this option.
    - Solution: Remove the `tests_require` option from the `setup.py` file. Alternatively, if you need those dependencies, specify them under `extras_require`.

2. **'extras_require' must be a dictionary**:
    - The error message indicates that `extras_require` is incorrectly formatted. It must be a dictionary where keys are features (like `"dev"` or `"test"`) and values are strings or lists of strings that specify additional dependencies.
    - Solution: Check and fix the formatting of the `extras_require`. Ensure it is properly formatted as a dictionary. For example:
      ```python
      extras_require={
          'test': ['pytest', 'mock'],
          'dev': ['check-manifest'],
      },
      ```

3. **General Troubleshooting Steps**:
    - **Ensure Dependencies**: Ensure you have the latest versions of `setuptools` and `pip` installed, as older versions might not be fully compatible with the package’s setup requirements:
      ```bash
      pip install --upgrade pip setuptools
      ```

    - **Review setup.py**: If you have access to the `setup.py` file, manually inspect and correct any potential issues.

    - **Virtual Environment**: Ensure that your virtual environment is set up correctly and used for the installation. Sometimes, recreating the virtual environment can resolve issues:
      ```bash
      python -m venv .venv
      source .venv/bin/activate  # On Windows, use: .venv\Scripts\activate
      ```

4. **Contact Developers**:
    - If you are working with an actively maintained package and cannot adjust the `setup.py` yourself, consider reaching out to the maintainers through their issue tracker or support channels. They might already be aware of the issue and have a fix or workaround.

5. **Alternative Installation**:
    - If the package is available via a different source (such as Conda if you are using it), you might explore installing it through that source:
      ```bash
      conda install -c conda-forge gym
      ```

Making these modifications should help in addressing the errors you are encountering during the installation process.

    raise ImportError(
ImportError: Missing shimmy installation. You provided an OpenAI Gym environment. Stable-Baselines3 (SB3) has transitioned to using Gymnasium internally. In order to use OpenAI Gym environments with SB3, you need to install shimmy (`pip install 'shimmy>=0.2.1'`).
Assistant: The error message indicates that the Stable-Baselines3 (SB3) package, which you're using for reinforcement learning, has transitioned from using OpenAI's Gym library to Gymnasium. However, you're trying to use an OpenAI Gym environment with SB3. To resolve this, you need to install an additional package called `shimmy`, which acts as a bridge to support OpenAI Gym environments with SB3.

Here's what you can do:

1. **Install Shimmy**:
   - Open your terminal or command prompt.
   - Activate your virtual environment if it isn't already activated:
     - On Windows: 
       ```bash
       .venv\Scripts\activate
       ```
     - On macOS/Linux:
       ```bash
       source .venv/bin/activate
       ```
   - Run the following command to install shimmy:
     ```bash
     pip install 'shimmy>=0.2.1'
     ```

2. **Verify Installation**: After installing shimmy, rerun your script or program to ensure that the issue is resolved. The error should no longer appear if the shimmy package is correctly installed.

3. **Use Gymnasium (Optional)**: Given that SB3 is now using Gymnasium, consider migrating your environments from Gym to Gymnasium if possible. This might not be necessary for your current setup if shimmy works adequately, but it's a good long-term consideration:
   - You can install Gymnasium via pip if you decide to migrate:
     ```bash
     pip install gymnasium
     ```

These steps should resolve the ImportError and allow you to continue using SB3 with OpenAI Gym environments.

Assistant: It looks like `gymnasium` is already installed in your virtual environment, which means you should be able to use its features or environments directly. However, if you still intend to use OpenAI Gym environments with Stable-Baselines3 and are encountering issues, you need to ensure that `shimmy` is installed to bridge the compatibility gap between OpenAI Gym and Stable-Baselines3.

Here's how you can proceed:

1. **Ensure Shimmy is Installed**:
   - Since you already have Gymnasium installed, make sure that `shimmy` is also installed:
     ```bash
     pip install 'shimmy>=0.2.1'
     ```

2. **Verify Compatibility and Dependencies**:
   - Check that you are using compatible versions of `gymnasium`, `stable_baselines3`, and `shimmy` to avoid any mismatch issues.
   - You can list installed packages and their versions with:
     ```bash
     pip list
     ```

3. **Use Gymnasium Environments**:
   - If your code is compatible, consider updating your environment names from Gym to Gymnasium. This is the recommended approach as SB3 natively supports Gymnasium environments. You might only need to modify the environment string identifiers in your code.

4. **Test Your Setup**:
   - After installing the necessary packages, test your script to make sure everything works smoothly.
   - If you are still facing problems, consider isolating the section of code where the issue arises and test it independently to debug efficiently.

If you follow these steps and ensure all dependencies are properly installed and compatible, you should be able to use Stable-Baselines3 with either Gymnasium environments or with OpenAI Gym environments via `shimmy`. If issues persist, it may be related to code-specific scenarios, and providing more context or checking compatibility notes from the package documentation might help resolve remaining issues.

    from gymnasium.wrappers.monitoring import video_recorder
ModuleNotFoundError: No module named 'gymnasium.wrappers.monitoring'
Assistant: The `ModuleNotFoundError` you're encountering indicates that the code is attempting to import a module or submodule from Gymnasium that either doesn't exist or isn't placed correctly in the directory structure you're using. The `gymnasium.wrappers.monitoring` was likely renamed or restructured if it's not found in the current Gymnasium version you're using.

Here's a series of steps you can take to troubleshoot and resolve this issue:

1. **Check Gymnasium Documentation**:
   - Review the latest Gymnasium documentation or release notes to understand any restructuring related to the `wrappers` or `video_recorder` functionality. It's possible that the structure or naming has changed.

2. **Verify Gymnasium Version**:
   - Ensure you have the latest version of Gymnasium installed. There might be bug fixes or updates that address the issue you're encountering.
   - Check your current install version:
     ```bash
     pip show gymnasium
     ```
   - If you're not on the latest release:
     ```bash
     pip install --upgrade gymnasium
     ```

3. **Modify Import Path**:
   - If the module path has changed, you might need to adjust the import statements accordingly based on any updates in the Gymnasium library.
   - Check if `video_recorder` exists in a different subpackage within Gymnasium.

4. **Alternative Functionality or Custom Implementation**:
   - If the particular monitoring functionality you need is not directly available or has been moved elsewhere, consider using alternative wrappers or implementing simple recording functionalities yourself.

5. **Look for Community Solutions**:
   - Sometimes, the open-source community identifies these issues quickly and provides workarounds or forks. Check places like GitHub issues for Gymnasium and Stable-Baselines3.

6. **Temporary Removal**: 
   - As a temporary measure, if the video recording functionality is not critical to your tasks, you could comment out or remove the related imports and usages. This will help you progress with other functionalities and later revisit the issue when the need for recording becomes critical.

These steps should help you diagnose and correct or work around the issue you are encountering with the module not being found. If you continue to have issues, consider providing additional context about your codebase or specific tasks that could be influencing the environment setup.

    from gymnasium.wrappers.monitoring import video_recorder
ModuleNotFoundError: No module named 'gymnasium.wrappers.monitoring'
Assistant: The `ModuleNotFoundError` suggests an issue with the import path for the `video_recorder` within Gymnasium. This problem occurs because the location or existence of `video_recorder` might have changed in the transition from Gym to Gymnasium, and Stable-Baselines3 might not have been updated accordingly to reflect these changes.

Here's how you can handle this situation:

1. **Check for Changes in Gymnasium**:
    - Gymnasium may have reorganized or removed certain modules and functions. Check their [official documentation](https://gymnasium.farama.org/) or their GitHub repository to see if there's any information on changes to the `monitoring` wrapper or `video_recorder`.

2. **Use an Older Version of Gymnasium**:
    - If the functionality has been removed in newer versions, you can try installing an older version of Gymnasium where the module path is still valid:
      ```bash
      pip install gymnasium==0.29.1
      ```
    - Replace `0.29.1` with an appropriate version that you know worked previously.

3. **Contact or Check with Stable-Baselines3 Developers**:
    - Look for existing issues or start a discussion on the Stable-Baselines3 GitHub repository to check if this is a known problem.
    - Developers might have provided a workaround or a patch.

4. **Manually Adjust the Code**:
    - If you are comfortable making changes, locate the `vec_video_recorder.py` within the `stable_baselines3.common.vec_env` directory and adjust the import path, if you find where `video_recorder` is defined, or remove/comment it if it's not required.

5. **Alternative Video Recording Solutions**:
    - If video recording is crucial, consider implementing it using a different library, such as OpenCV or a custom recording script, outside of the Gym/Gymnasium integration, to capture your environment's outputs.

6. **Implement a Shim Layer**:
    - You can create a small custom function to replicate the missing `video_recorder` functionality if feasible. This would depend on being able to identify the required capabilities from other available Gym/Gymnasium components.

Note: Before making extensive changes or downgrading, consider if video recording is essential for your task or if the application can run without it temporarily. There might be updates in these libraries addressing these integration issues by either the Stable-Baselines3 or Gymnasium teams in the future.

By addressing or working around these import issues, you should be able to move forward without the `ModuleNotFoundError` stopping the functioning of your script.

Assistant: The issue you're encountering is twofold: a warning about using OpenAI Gym environments with Stable-Baselines3 and an assertion error related to the `render_mode` not being set to `"rgb_array"`. Here's how you can address these:

1. **Transition from Gym to Gymnasium**:
   - The warning suggests that you should transition from using OpenAI Gym environments to Gymnasium environments. Gymnasium is more up-to-date and is being recommended by the developers of Stable-Baselines3.
   - Update your code to use Gymnasium environments if possible. If you're using an environment like `"CartPole-v1"`, ensure that it's created using the Gymnasium library:
     ```python
     import gymnasium as gym

     env = gym.make("CartPole-v1", render_mode="rgb_array")
     ```

2. **Set `render_mode` to `"rgb_array"`**:
   - The assertion error indicates that the `render_mode` of your environment is not set. To use `VecVideoRecorder`, you need to ensure that `render_mode` is explicitly set to `"rgb_array"`.
   - When creating your environment, set `render_mode`:
     ```python
     env = gym.make("CartPole-v1", render_mode="rgb_array")
     ```

3. **Modify Environment Creation**:
   - Ensure that when creating the environment and wrapping it with other wrappers, they don't override the `render_mode`.
   - If you're extending this to other configurations, verify the set-up parameters for each kind of environment or wrapper.

4. **Error on `DummyVecEnv`**:
   - The secondary issue (AttributeError) in the cleanup logic (`__del__` method) points to something being amiss during destruction. This might be due to the unresolved assertion causing backtracking issues.
   - Ensure all the necessary attributes are initialized correctly when the `VecVideoRecorder` is created, and `render_mode` mismatch is resolved to stabilize the environment behavior.

5. **Verify Imports and Compatibility**:
   - Double-check that you are using the correct imports aligned with Gymnasium and make sure compatibility patches or fixes from Stable-Baselines3 work with updated libraries.

By setting `render_mode` correctly and shifting to Gymnasium environments, you should be able to address the primary issues and help stabilize your script execution. If this continues to fail, reviewing the library documentation for potential updates, pending issues, or patches related to these specific errors might offer additional guidance.
