How to resolve "ImportError: DLL load failed:" on Python?

I just encountered this exact problem and was struggling to solve it. I tried to reinstall anaconda, I reinstalled the relevant packages, I changed my environment - BUT NOTHING WORKED! eventually, after few hours, I managed to solve this problem with some few easy steps as described here :)

just type in the command line (one code-line at a time): conda install numpy then, conda install scipy then, pip install -U seaborn then, pip install -U numpy and finally, pip install -U scipy

That's it :) - it is now working! (it also fixed the error for all of the other libraries as well, such as sklearn, matplotlib etc.)

I have managed to resolve the problem by reinstalling Python. First, I have uninstalled Python (like any other program in Windows). Then I have installed Anaconda distribution of Python. The problem is not present anymore.

If anyone comes across this issue in Python > 3.8 with Windows, dll's are only loaded from trusted locations https://docs.python.org/3/whatsnew/3.8.html#ctypes This can be fixed by adding the dll path using os.add_dll_directory("PATH_TO_DLL")
