dependency errors in Google Colab

[nickwan]

Hi all, just doing a simple pip install carball in a Google Colab notebook and getting the following install errors:

ERROR: tensorflow-metadata 0.15.2 has requirement protobuf<4,>=3.7, but you'll have protobuf 3.6.1 which is incompatible.
ERROR: plotnine 0.6.0 has requirement pandas>=0.25.0, but you'll have pandas 0.24.2 which is incompatible.
ERROR: mizani 0.6.0 has requirement pandas>=0.25.0, but you'll have pandas 0.24.2 which is incompatible.
ERROR: google-colab 1.0.0 has requirement pandas~=0.25.0; python_version >= "3.0", but you'll have pandas 0.24.2 which is incompatible.
ERROR: datascience 0.10.6 has requirement folium==0.2.1, but you'll have folium 0.8.3 which is incompatible.
ERROR: albumentations 0.1.12 has requirement imgaug<0.2.7,>=0.2.5, but you'll have imgaug 0.2.9 which is incompatible.

wondering what the plans are for updating these dependencies?

We already have a pull request to update protobuf to latest version. But it needs tests and I can't get the time to do that for the next 2 weeks. If you add some tests then we can get that updated. It mostly needs extra tests for converting too and back from json. And to and from binary data.
