Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll
After using Anaconda to create a virtual environment, then install scikit-learn, numpy, pandas, Matplotlib and other data analysis libraries. Write a linear regression in pycharm, and then report the error: Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll
A lot of information has been checked. The explanation on the Internet is that the numpy package without MKL is free and can not handle massive data types.
Then you can reinstall the numpy with MKL.

And then install it in Anaconda
pip install "numpy-1.14.3+mkl-cp27-cp27m-win_amd64.whl" # The quotation marks are the files you download. Remember CD to the directory you downloaded.
The perfect solution.
