raise VersionConflict(dist, req).with_context(dependent_req) pkg_resources.ContextualVersionConflict: (numpy 1.19.5 (/home/wzd/anaconda3/envs/wzdpython/lib/python3.9/site-packages), Requirement.parse('numpy>=1.20.3'), {'pandas'})

The error message you provided suggests a version conflict between the required version of numpy and the version installed in your environment. The specific requirement is numpy >= 1.20.3, but you have numpy 1.19.5 installed.

To resolve this issue, you have a few options:

1. Update numpy: You can try updating numpy to the required version using the following command:

   python -m pip install --upgrade numpy

2. Update pandas: It seems that there is a dependency on numpy from pandas. You can try updating pandas, which might also update numpy to a compatible version:

   python -m pip install --upgrade pandas

3. Create a new environment: If updating numpy or pandas is not feasible due to other dependencies, you can create a new virtual environment and install the required versions of numpy and pandas in that environment:

   python -m venv myenv
   source myenv/bin/activate  # For Linux/Mac
   myenv\Scripts\activate  # For Windows
   python -m pip install numpy==1.20.3 pandas

By creating a new environment, you can isolate the dependencies and ensure that the required versions are installed without conflicts.

Please let me know if you encounter any further issues or if there's anything else I can assist you with!
