- Check Python Path in MATLAB: Make sure MATLAB is recognizing the correct Python environment where obspy is installed. You can check this using the pyenv command, which you've already done. Ensure that the environment is active and that the paths are correctly set.
- Verify Installation of Obspy: Ensure that obspy is correctly installed in the specified environment. You can verify this by running Python within the same environment outside of MATLAB and checking if you can import and access obspy.clients.fdsn.Client without any issues.
- MATLAB Python Compatibility: Ensure that your version of MATLAB is compatible with Python 3.11. While MATLAB typically supports the latest versions of Python, there can sometimes be compatibility issues, especially with newer Python versions.
- Module Initialization: Some Python modules require initialization steps that might not be automatically handled by MATLAB's Python integration. It's worth checking obspy's documentation to see if there are any such requirements.
- Dependencies and Submodules: Sometimes, the issue might be with dependencies of a particular submodule within a Python package. Ensure all dependencies of obspy.clients.fdsn are properly installed and accessible in the environment.
- MATLAB's Python Integration Limitations: Be aware that MATLAB's integration with Python has certain limitations. Not all Python libraries and their functionalities are fully compatible or accessible from within MATLAB.
- Test with a Simple Python Script: Create a simple Python script that imports and uses obspy.clients.fdsn.Client, and run this script from MATLAB using the system command. This can help you determine if the issue is with MATLAB's Python interface or with the Python setup itself.
- MATLAB Support and Documentation: Consult MATLAB's documentation for any known issues or special instructions regarding Python integration, especially with complex libraries like obspy. Additionally, consider reaching out to MathWorks support for assistance.
- Permission Issues: While less likely, there could be permission issues, especially if MATLAB is running with different permissions compared to your standard Python environment.
- Reinstall Obspy: As a last resort, try reinstalling obspy in your Python environment. Occasionally, reinstallation can resolve path or dependency issues.
- Downgrading/Upgrading libraries: Downgrading or updating the libary may help.
