i copied the numpy and cython installed files into the same repositary where the library was installed and it worked.

@samitnissrine I tried to copy the numpy and cython installed files into the same folder where the library was installed. Still It's not working. Getting the same error which is mentioned above. Can anyone please help on this?

Please install numpy and cython using the command below: On Windows, you can run this on the command line or PowerShell.

pip install numpy cython

Then, try to install LibTwinSVM from source:

pip install .

See the installation guide here.

@mir-am Thanks for the quick response. I tried to install the library after installing the dependencies itself. still getting the same error. Attached the screenshot for reference.

Please let me know what I am missing here.
Thank you

@Hariniinduri. Thanks for reporting the issue. I need to test the installation on my machine to see if I can reproduce the issue on Windows. I will keep you updated about a possible solution here by the end of the week.
