tropo_pyaps3.get_snwe(): return native int instead of numpy.int64

[fukun364202818]

In the get_snwe function within tropo_pyaps3.py, the original return (S, N, W, E) was returning S, N, W, and E as NumPy's np.int64 type, while the expected type was standard Python's int. Therefore, I modified the return statement to return (int(S), int(N), int(W), int(E)), which successfully fixed the problem.

Reviewer's Guide by Sourcery

The pull request addresses a type mismatch in the get_snwe function within tropo_pyaps3.py. The function was returning NumPy's np.int64 type integers, but the expected type was standard Python's int. The return statement was modified to cast the variables to the correct type.

PR Summary

This Pull Request addresses a bug in the get_snwe function within the tropo_pyaps3.py file. The issue was that the function was returning values as NumPy's np.int64 type, which was incompatible with the expected standard Python int type. The modification involves changing the return statement to explicitly convert the values to standard Python int, ensuring compatibility with other parts of the codebase, particularly with cdsapi-0.7.3, which does not support np.int64. Additionally, the PR comments out assertions that checked for integer types, reflecting a shift in type handling strategy.

Suggestion

While the current fix resolves the immediate issue, consider reviewing other parts of the codebase where similar type mismatches might occur, especially if interfacing with external libraries that have specific type requirements. Additionally, if the commented-out assertions are no longer necessary, consider removing them entirely to maintain clean and readable code.
