Python version : 3.5.2
I getting started with machine learning and things... So I installed sklearn and some other packages form pip. All of them were able to be installed successfully except sklearn so, I downloaded the wheel and installed it from here. It was successfully installed but when i tried to import it in the order to check correct installation, I got tons of error :
Traceback (most recent call last): File "C:\MyFiles\Programs\Python\PlayGround.py", line 1, in import sklearn

ImportError: DLL load failed: The specified module could not be found.
And the code was just :
import sklearn
I have already checked correct version of wheel package which, I have downloaded.
How can I correct it and why it is occurring?
回答1:
The following steps solved my problem :
- Uninstalling numpy, sklearn and scipy.
- Downloading numpy+mkl and scipy from here.
- Firstly installing numpy+mkl and then scipy.
- Installing sklearn from pip.
回答2:
Various things need to be checked:
- Check numpy, scipy installation versions.
- If they are correct then try to import numpy and scipy.
- If they getting imported correctly, then clear your
temp(c:/users/username/Appdata/local/temp)folder. Restart the machine and try again. - Still if doesn't work, then uninstall scipy, numpy , sklearn and reinstall the proper wheel files
回答3:
Download and install numpy+mkl file.
Currently you might have installed only the numpy file.
Go to: https://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
Download the corresponding wheel file in which is suitable for your python installation
pip install "/path_to_thefile/numpy-1.14.6+mkl-cp36-cp36m-win_amd64.whl"
This should help you
