Same error here occurring on multiple machines. I should note that after running into this error on a first trial with Google Collab, I re-ran the code and it worked.

[jaymanjunath]

Same error here, re-run didn't work for me

[evan-burke]

Tip: this may be happening because the training subprocess is crashing; if so, Jupyter/ipython/colab won't show exceptions from that because it's being run in a separate process.

If you run automl_gs on the command line, you should see the exception from the model.py subprocess (in addition to this exception), which might give you more insight into what's breaking.

Like @evan-burke said, this can happen when a subprocess crashes. Running from the command line is one option, but I was also able to see the error by looking at my Jupyter log.

(In my case the problem was automl-gs using the wrong Python version (see #26). Once I corrected that, I ran into a MemoryError.)
