It appears that some versions of pip do not recognize this option
when it appears in the requirements file. Did not explore this further
but recommend --prefer-binary in the manual install instructions on
the command line.
- This is only a test!
- The various environment*.yml and requirements*.txt files have all
been moved into a directory named "environments-and-requirements".
- The idea is to clean up our root directory so that the github home
page is tidy.
- The manual install instructions will start with the instructions to
create a symbolic link from environment.yml to the appropriate file
for OS and GPU.
- The 1-click installers have been updated to accommodate this change.
