Cannot install Theano libgpuarray on Windows 10

This question is for Python2.7 with Keras as a front end. I have Microsoft Visual Studio 2017 and I believe I have all the tools it needs. I followed the instructions on install CUDA. I believe it is version 10, and I think it is installed correctly. I followed the tutorial video and got a similar result at the end for the sample test. I have now moved on to installing libgpuarray. I have completed the following steps and got this error: 

C:\Windows\system32>cd C:\Users\Never\Downloads\libgpuarray

C:\Users\Never\Downloads\libgpuarray>cd Build

  The OLD behavior for policy CMP0063 will be removed from a future version

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

I tried running C:\Users\Never\Downloads\libgpuarray\Build>make next but it returned:

'make' is not recognized as an internal or external command,operable program or batch file.

There is a make script in the folder above so I tried using it, with this result:

C:\Users\Never\Downloads\libgpuarray\Build>C:\Users\Never\Downloads\libgpuarray\make.bat

C:\Users\Never\Downloads\libgpuarray\Build>REM This helps repetitive builds on windows

C:\Users\Never\Downloads\libgpuarray\Build>REM and it will build a release version

C:\Users\Never\Downloads\libgpuarray\Build>del bld

C:\Users\Never\Downloads\libgpuarray\Build>mkdir bld

C:\Users\Never\Downloads\libgpuarray\Build>cd bld

C:\Users\Never\Downloads\libgpuarray\Build\bld>cmake .. -G "NMake Makefiles" -DCMAKE_BUILD_TYPE=Release
CMake Error: Error: generator : NMake Makefiles
Does not match the generator used previously: Visual Studio 15 2017
Either remove the CMakeCache.txt file and CMakeFiles directory or choose a different binary directory.

C:\Users\Never\Downloads\libgpuarray\Build\bld>cmake --build . --config Release
Error: could not load cache

C:\Users\Never\Downloads\libgpuarray\Build\bld>cd ..

I am not 100% sure what to do next. I don't want to tinker and break things further, any assistance would be appreciated, thank you.

It looks like you are following the Linux instructions in the tutorial you linked. You should probably take a look at the Windows-specific instructions, considering you are building on Windows with Visual Studio.

It sounds like you may have corrupted your CMake cache a bit by running the make.bat file, so it's probably best to delete your Build folder and start over:

C:\Users\Never\Downloads\libgpuarray>mkdir Build && cd Build
C:\Users\Never\Downloads\libgpuarray\Build>cmake ..

From there, just follow the Windows-specific guidelines from the tutorial:

It will generate a Visual Studio solution file for the version installed. To build the project open this file (.sln) and run the “Build All” command after selecting the appropriate build type.
