Fix for Windows install

[Ivan-267]

With the changes from the PR, I was able to install this in Windows 10 64 bit and run inference on my CPU.

Prior to the changes, pip install commands would fail at:

  Installing build dependencies ... done
  Getting requirements to build wheel ... error
  error: subprocess-exited-with-error    

With the error:

site-packages\setuptools\_distutils\util.py", line 134, in convert_path
          raise ValueError("path '%s' cannot end with '/'" % pathname)
      ValueError: path './' cannot end with '/'

According to the error message, I have removed the / which fixed the issue for me.
Please feel free to retest that everything is still fine for Linux when considering the PR.
