AttributeError: module 'numpy' has no attribute 'long'

I also have the same issue when importing Momepy

@sarah-blanchette Please provide the following information as stated in the issue template:

• Platform information:

>>> import os; print(os.name, os.sys.platform);print(os.uname())

• Python version:

>>> import sys; print(sys.version)

• SciPy version:

>>> import scipy; print(scipy.__version__)

• NumPy version:

>>> import numpy; print(numpy.__version__)

Also, please provide the versions of libpysal and momepy you are running and how they were installed (pip, conda, etc.).

[jGaboardi]

Locally, I am not seeing any problems:

Python 3.12.0 | packaged by conda-forge | (main, Oct  3 2023, 08:43:38) [Clang 15.0.7 ]
Type 'copyright', 'credits' or 'license' for more information
IPython 8.16.1 -- An enhanced Interactive Python. Type '?' for help.

In [1]: import libpysal

In [2]: from libpysal import weights

In [3]: libpysal.__version__
Out[3]: '4.8.0'

[sarah-blanchette]

Here it is. I'm thinking it has to do with the Numpy version, but I had to downgrade it for another library. Also I used pip to install pysal

os name and platform: posix darwin
os uname: posix.uname_result(sysname='Darwin', nodename='MacBook-Air-93.local', release='22.5.0', version='Darwin Kernel Version 22.5.0: Mon Apr 24 20:52:43 PDT 2023; root:xnu-8796.121.2~5/RELEASE_ARM64_T8112', machine='x86_64')

scipy: 1.10.1
numpy: 1.24.4

[jGaboardi]

• What version of libpysal and momepy are you running?
• Did you install pysal or libpysal?

[sarah-blanchette]

libpysal: (4.8.0)
momepy: (0.6.0)

I installed both libpysal and pysal

[jGaboardi]

Hmmm. OK. pip is the troublemaker more often than not in there kinds of scenarios. I would suggest try to create your environment again entirely from conda-forge.

Testing are passing on oldest environment we support, where numpy=1.22.4, and the latest, where numpy=1.26.0. So it probably isn't an issue with numpy itself.

[martinfleis]

This may be related to the numba version. Can you please post full Traceback? Not the truncated one? It is unclear where the long is being called as that happens where the ... is.

[jGaboardi]

'm thinking it has to do with the Numpy version, but I had to downgrade it for another library

Also, which is the "other library?" Is it numba as @martinfleis suggested?
