Error running preprocess.py

[Mark Richman]

I got the following error when performing the preprocess step on the LJ speec dataset (crashed halfway through):

$ python3 preprocess.py
/home/ubuntu/.local/lib/python3.6/site-packages/numba/errors.py:137: UserWarning: Insufficiently recent colorama version found. Numba requires colorama >= 0.3.9

The above exception was the direct cause of the following exception:

Disregard. Partition was full.
