Fix CircleCI issues

[ManuelAlvarezC]

Hi!

This is WIP. Please don't merge nor dismiss. READ BELOW

I was checking the CircleCI errors here.

Install dependencies

ERROR: matplotlib 3.3.2 has requirement certifi>=2020.06.20, but you'll have certifi 2019.9.11 which is incompatible.
ERROR: wandb 0.10.4 has requirement six>=1.13.0, but you'll have six 1.12.0 which is incompatible.
ERROR: google-api-core 1.22.4 has requirement six>=1.13.0, but you'll have six 1.12.0 which is incompatible.
ERROR: google-cloud-bigquery 2.0.0 has requirement six<2.0.0dev,>=1.13.0, but you'll have six 1.12.0 which is incompatible.
ERROR: torchvision 0.6.1 has requirement torch==1.5.1, but you'll have torch 1.6.0 which is incompatible.

Decoder tests

  File "/home/circleci/repo/flood_forecast/gcp_integration/basic_utils.py", line 2, in <module>
    from google.cloud import storage

  ...

  File "/usr/local/lib/python3.7/site-packages/google/cloud/_http.py", line 23, in <module>
    from six.moves import collections_abc
ImportError: cannot import name 'collections_abc' from 'six.moves' (unknown location)

I think that the issue is caused by the wrong dependency versions (in this case six package on a google.cloud third dependency, but others could arise later on), and/or by the new pip resolution method[1][2] combined with a requirements file without the versions pinned down.

So I pinned down the versions to the requirements that caused the issue and I could make it work on a clean virtualenv running with python3.7.

If when I open PR and this branch runs on CircleCI, everything is fine, then I will pin down all the other requirements and that will be the end of it, it that's not the case I will check using a different image with the circleCI setup file.

UPDATE

The installation errors are gone, yet the build still crashed, this time caused by a test that requires user input.

From the CircleCI logs:

wandb: (1) Create a W&B account
wandb: (2) Use an existing W&B account
wandb: (3) Don't visualize my results
wandb: Enter your choice: Traceback (most recent call last):


File "/home/circleci/repo/flood_forecast/time_model.py", line 42, in __init__
    self.wandb = self.wandb_init()
  File "/home/circleci/repo/flood_forecast/time_model.py", line 89, in wandb_init
    tags=self.params["wandb"]["tags"])
  File "/usr/local/lib/python3.7/site-packages/wandb/sdk/wandb_init.py", line 500, in init
    six.raise_from(Exception("problem"), error_seen)

You can run the same comand on your local machine and see how the prompt pops out:.

python flood_forecast/trainer.py -p tests/transformer_bottleneck.json
