Latest release of Pandas (1.4.3) cannot be used with the latest release of pandas-stubs (1.4.2.220626)

[aholmes]

Hi,
The latest version of pandas-stubs (1.4.2.220626) depends on Pandas version 1.4.2. This prevents updating to Pandas 1.4.3 if we want to use the latest version of pandas-stubs.

ERROR: Cannot install -r requirements.txt (line 22) and pandas==1.4.3 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested pandas==1.4.3
    pandas-stubs 1.4.2.220626 depends on pandas==1.4.2

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

hmm I see, I think the package version should be based on api version and the date like "1.4.220626" or "1.4.0.220626", so the minor version would not be affected.

I'll work on a new release this weekend that should address this issue

[aholmes]

Out of curiosity I made the changes above. I attempted to run the tests locally (following this), but pyright fails. All of the workflows succeed in GitHub actions though. What am I missing, and is f9f0b0f sufficient?

Try to delete .cache folders

[aholmes]

None exist. I had tried removing __pycache__ folders though.

When you changed the pandas and project version did you update poetry.lock file with poetry update ?

[aholmes]

I had initially done poetry lock --no-update, which did update the versions in the file. However, deleting poetry.lock and going through the process again had the same effect.

Good news though - I noticed which python came from ~/.cache when I was in the poetry shell. I removed the directory and started over. The tests pass locally now. Thanks for the tip!
