When I executing "from _anomaly_kernel_cython import median_filter" -->
ImportError: Building module _anomaly_kernel_cython failed: ['distutils.errors.DistutilsPlatformError: Unable to find vcvarsall.bat\n']

I have installed Microsoft LightSwitch for Visual Studio 2015 14.0.25431.01 Update 3

Hello, the other day I found the solution to this issue.

Cython is C code that integrates with Python to make code more efficient. The .pyx file needs to be compiled to generate the C file.

I executed the following command and I already managed to run the code:

python setup.py build_ext --inplace

Hello, this command does not work on my side. I have an error message related to Cython... Any help please?

Ouput of:

python setup.py build_ext --inplace

Please can you indicate the version of Python and Cython you are using? I am working on Mac OS by the way.

Versions on my side:

Python: 3.9.4
Cython==3.0.4
numpy==1.26.1
pandas==2.1.1

Issue solved with:

pip install Cython==3.0.3
python setup.py build_ext --inplace
python setup.py install
