Cannot import name 'literal' from typing.

[arnaumarin]

I am trying to run on a Linux the example for "mnist_keras_loihi.py". After installing the setup.py and the dependencies, I find the following error:
File "/path/miniconda3/envs/mearl/lib/python3.7/site-packages/termcolor-2.4.0-py3.7.egg/termcolor/_types.py", line 3, in
from typing import Literal
ImportError: cannot import name 'Literal' from 'typing' (/home/harvard/miniconda3/envs/mearl/lib/python3.7/typing.py)

I am using Python 3.7 and I finished processing dependencies for snntoolbox==0.6.0.
Any advice ?
