Couple of dependencies and build issues

[Vedaant-J]

Hi,

I have trying to replicate the experiments, found 3 build/dependency issues

1. in version.py, please change "joint"->"spr_pick"

2. Also what is the version of colored_traceback that should be used as some attributes are not available in recent releases.

3. There is no generate_train_files.py file

Thanks for catching 1, we will fix that. We're using version 0.3.0 of the colored_traceback package. We are looking into 3.
