ensemble throwing error of file not found for timeout

sigopt_clf.parallel_fit(X_work, y_work, est_timeout=(40 * 60),

for the ensemble classifier is throwing:

Hi @geoHeil, sorry for the very very late reply on this. The SigOpt sklearn library uses timeout under the hood to control running some of its jobs. Because the underlying library uses Popen to run the timeout process, if the machine running SigOpt sklearn does not have the timeout utility, the code will manifest in this error.

We've filed an internal error but I don't have an estimate for when this will get fixed. For now, I'd suggest running your code in a linux environment, such as an AWS instance or a Google Collab notebook, which I believe should have timeout installed.

Alternatively, if you're running on a mac, you can install gtimeout through the coreutils library:

$ brew install coreutils

And then alias timeout to gtimeout, by putting the following in your .bashrc or .bash_profile:

alias timeout="gtimeout"
