I found solutions by looking at the following posts

https://github.com/dmlc/xgboost/issues/1644 https://stackoverflow.com/questions/18138635/mingw-exe-requires-a-few-gcc-dlls-regardless-of-the-code

When I created mingw-w64 in the C:\mingw-w64 location then it works and by adding following lines to the notebook

import os mingw_path = 'C:\mingw-w64\x86_64-7.2.0-posix-seh-rt_v5-rev1\mingw64\bin' os.environ['PATH'] = mingw_path + ';' + os.environ['PATH']
