Setup.py fails for pip>=20.1

[Andrej730]

Still an issue for me to install chumpy either with pip install git+https://github.com/mattloper/chumpy.git or pip install chumpy. #41 solves the problem for me.

Fast solution for now is to install it with scottandrews@fe51783:
pip install git+https://github.com/scottandrews/chumpy.git@fe51783e0364bf1e9b705541e7d77f894dd2b1ac

[gormonn]

it works to install chumpy, for me:
pip install --force-reinstall pip==19

sorry I have added the original gt repo earlier. Following works fine.
pip install git+https://github.com/scottandrews/chumpy.git

Tried chumpy previous versions and downto 0.66, no version worked. Then they were not compatible with my tasks.

UPDATE

Tried on ubuntu 16.04. does not work either. works fine on macos. but I need tf-gpu but I dont have gpus on my mac(currently running debian 9 on GCP)
