Train-curve ends in error (module 'plotext' has no attribute 'colorless')

Hello everyone.

I was using train-curve, with the following results:

=========================== Train curve diagnostic ===========================
Training 5 times with 20%, 40%, 60%, 80%, 100% of the data

AttributeError: module 'plotext' has no attribute 'colorless'

As you can see, the results table displays normally, just to fail afterwards, during the curve plotting, with the error AttributeError: module 'plotext' has no attribute 'colorless'. BTW I am currently using prodigy==1.11.7 and plotext==5.0.2. The only thing I have found in 'plotext' changelog, vaguely related to my issue, is this one, but no naming convention change was found (as in this case).

Is there any "plotext recommended version"? Other than that, any ideas?

Hi @dave-espinosa ,

Can you try installing plotext==4.2.0? It seems that plotext released a major version a few days ago and removed the colorless parameter and replaced it with clear_color. Thanks for reporting this too!

Hello @ljvmiranda921 ,

I have downgraded to plotext==4.2.0, and I am now getting the desired graph:

✔ Accuracy improved in the last sample
As a rule of thumb, if accuracy increases in the last segment, this could
indicate that collecting more annotations of the same type will improve the
model further.

Therefore, the containment solution works.

I am curious now: Is prodigy "automatically" updated or not, by any chance?

The reason I am asking this, is because if it is not, then I think we can keep working with this containment; however if it is, then of course we might need to upgrade plotext once this issue appears again.

Let me know your comments please.

Thank you!

Hi @dave-espinosa , similar to any Python dependency, you have to update Prodigy via pip. For now, if you have a project that uses train-curve, you can pin the plotext dependency in your requirements.txt file

# requirements.txt
prodigy
plotext==4.2.0

I think pinning some dependencies is actually a good practice to maintain the same environment all throughout. Especially given that third-party dependencies tend to update and be "out-of-sync" with one another.

I hit the same error and was about to start a new thread, but thanks to suggestions, saw this one, which solved my problem. So, thanks a lot! @dave-espinosa and @ljvmiranda921! :slight_smile:
