Importing Nengo_DL in Google Colab

[SerhiiBahdas]

Hello there!

I'm encountering an issue with importing nengo_dl in Google Colab. The error states that 'keras.engine' is not available. Here's what I've tried:

1. Attempted to resolve it by downgrading keras to version 2.2.1 using 'pip install keras==2.2.1,' but a new error occurred.
2. The new error suggests that Colab cannot import 'Iterable' from 'collections,' possibly a Python compatibility issue.

Could you please help me resolve this? Thank you in advance, you guys are awesome!

@SerhiiBahdas please use my forked version where I have fixed the issue of keras.engine

pip install git+https://github.com/sleepingcat4/nengo-dl.git

I've opened a pull request to this library and hopefully the maintainers will merge it pretty quick
