problem in finding MSVC version

[reza]

I got this error when I tried to build caffe: 

The system cannot find the drive specified.

Exactly the same problem, including the MSVC 1800 and Python 3.5 codes.

Any luck finding a solution?

After looking further, the problem is in the cmake download of the pre-built binaries. 3.5 is listed but only for MSVC=1900 (presumably Visual Studio 2015).

After looking further, the problem is that the cmake download of the pre-built binaries doesn't list this specific combination. VS 2015 should work with either version of Python, but for VS 2013 only python 2.7 is currently supported.

Indeed, after swapping in Python 2.7 it worked fine.
