Import error when install chop on Colab

[GeoffNN]

When running !python -m pip install git+https://github.com/openopt/chop on a Google colab, I get the following error:

<ipython-input-2-f345500ab750> in <module>()
----> 1 import chop

1 frames
/usr/local/lib/python3.7/dist-packages/chop/stochastic.py in <module>()
     14 import torch
     15 from torch.optim import Optimizer
---> 16 from chop import utils
     17 import numpy as np
     18 

ImportError: cannot import name 'utils' from 'chop' (/usr/local/lib/python3.7/dist-packages/chop/__init__.py)

@fabianp any clue why this could happen?

just a guess, but maybe it should use relative imports?

This is very strange.

The following sequence works, and does not yield any import errors

git clone https://github.com/openopt/chop.git
cd chop
pip install .

But the following doesn't work:

pip install git+https://github.com/openopt/chop.git

The version on PyPi doesn't work either:

pip install chop-pytorch

....

Actually the last one works on my machine, just not on colab...

Fixed!
