Issue in importing k-means-constrained in Google Colab notebook #41

Closed bhattashreya closed 1 year ago

bhattashreya commented 1 year ago

Hi Josh,

I am having an issue import the k-means-constrained package in my Colab notebook. This was working a week ago but I have been receiving the following error this week, and was wondering if there is a package incompatibility due to the numpy version I am using:


RuntimeError                              Traceback (most recent call last)
__init__.pxd in numpy.import_array()

RuntimeError: module compiled against API version 0x10 but this version of numpy is 0xf . Check the section C-API incompatibility at the Troubleshooting ImportError section at https://numpy.org/devdocs/user/troubleshooting-importerror.html#c-api-incompatibility for indications on how to solve this problem .

During handling of the above exception, another exception occurred:

ImportError                               Traceback (most recent call last)

Could you please let me know how to resolve this? I have tried installing and uninstalling numpy, and trying to install specific versions of numpy but am still receiving this error. Thank you!

Hi, uploaded a new version to PyPI (v0.7.3) that uses a different method to compile for the numpy ABI. Can you try and see if it works:

pip install --upgrade k-means-constrained

I assume this is fixed and so closing the issue. Please reopen if this issue persists or create a new issue.
