Hi Andreas,
    I tried to reinstall pycuda from within my Miniconda3 command window, i.e., using the command... pip install pycuda.
    Everything goes well in the build until it tries to execute the following:

    C:\ProgramData\Miniconda3\Library\mingw-w64\bin\gcc.exe -mdll -O -Wall -DMS_WIN64 -DBOOST_ALL_NO_LIB=1 -DBOOST_THREAD_BUILD_DLL=1 -DBOOST_MULTI_INDEX_DISABLE_SERIALIZATION=1 -DBOOST_PYTHON_SOURCE=1 -Dboost=pycudaboost -DBOOST_THREAD_DONT_USE_CHRONO=1 -DPYGPU_PACKAGE=pycuda -DPYGPU_PYCUDA=1 -DHAVE_CURAND=1 -Isrc/cpp -Ibpl-subset/bpl_subset "-IC:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\include" -IC:\ProgramData\Miniconda3\lib\site-packages\numpy\core\include -IC:\ProgramData\Miniconda3\lib\site-packages\numpy\core\include -IC:\ProgramData\Miniconda3\include -IC:\ProgramData\Miniconda3\include -c src/cpp/cuda.cpp -o build\temp.win-amd64-3.6\Release\src\cpp\cuda.o /EHsc

Then I get this error message:
gcc: error: /EHsc: No such file or directory
error: command 'C:\\ProgramData\\Miniconda3\\Library\\mingw-w64\\bin\\gcc.exe' failed with exit status 1
.
So I thought that the gcc.exe folder needed to be added to the path, so I added it. Nevertheless, I got the same gcc: error: /EHsc: No such file or directory.

PATH=C:\ProgramData\Miniconda3;C:\ProgramData\Miniconda3\Library\mingw-w64\bin;C:\ProgramData\Miniconda3\Library\usr\bin;C:\ProgramData\Miniconda3\Library\;C:\ProgramData\Miniconda3\Scripts;C:\ProgramData\Miniconda3\Library\bin;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\bin;C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v9.0\libnvvp;C:\SciSoft\Python36\Scripts\;C:\SciSoft\Python36\; etc...

At the same time, the pip install provides the following message:

    *************************************************************
    *** I have detected that you have not run configure.py.
    *************************************************************
    *** Additionally, no global config files were found.
    *** I will go ahead with the default configuration.
    *** In all likelihood, this will not work out.
    ***
    *** See README_SETUP.txt for more information.
    ***
    *** If the build does fail, just re-run configure.py with the
    *** correct arguments, and then retry. Good luck!
*****************************************************************
However, there are no files named configure.py or README_SETUP.txt on my computer.
.
Please advise.
Thank you.
