Hello everyone.

I was using [train-curve](https://prodi.gy/docs/recipes#train-curve), with the following results:

```python
=========================== 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](https://pypi.org/project/plotext/2.2.0/#:~:text=the%20plots%20are%20printed%20with%20a%20default%20color%20combination%2C%20instead%20of%20default%20colorless%20one), but no naming convention change was found (as in [this case](https://support.prodi.gy/t/train-curve-ends-in-error-module-plotext-has-no-attribute-figsize/4590)).

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`](https://github.com/piccolomo/plotext/blob/3265d34ac3ae932d7b86398b2946fd33fd7365f2/readme/notes.md#main-updates). Thanks for reporting this too!

Hello @ljvmiranda921 ,

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

```python
=========================== Train curve diagnostic ===========================
Training 2 times with 50%, 100% of the data

% Score ner   
---- ------ ------
  0% 0.01 0.01  
 50% 0.48 ▲ 0.48 ▲
100% 0.54 ▲ 0.54 ▲

    ┌──────────────────────────────────┐
0.54┤ ▗▄▄▄▄▄▄▄▞▀▀▀▀│
0.48┤ ▗▞▀▀▀▀▘ │
    │ ▗▞▘ │
    │ ▄▀▘ │
    │ ▗▄▀ │
    │ ▗▞▘ │
    │ ▄▞▘ │
    │ ▄▀ │
0.01┤▄▀ │
    └┬────────────────┬───────────────┬┘
     0% 50% 100% 

✔ 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

```python
# 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.

Hello @ljvmiranda921 ,

Thank you very much for your guidance and recommendations.

From my side, please consider the case closed.

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! 🙂
