Thanks for the great tool. When using it, I ran into a bit of
an edge case. For some operators, the
reasonable _pre_test decorator (tpot/decorators.py)
can actually take an arbitrarily long amount of time, effectively
hanging the search (since it never moves past generating candidates).
The small sampled down pretest_X might be reasonable, but
for some operators complexity scales with columns (and it may be
hard to determine the correct number to sample, if any).
You can reproduce the issue by using the following example:

This will timeout, rather than finish appropriately
Possible fix
I have a simple patch that adds a timeout to the
.fit
call taking place at line 88 intpot/decorators.py
. I can PR it if this seems useful.The text was updated successfully, but these errors were encountered:
