Installation error / unmentioned dependency "bayes_opt"

[jotaf98]

Attempting to install by following the documentation's instructions, after installing all the mentioned dependencies with conda, results in the following error:

(base) user@server:~$ pip install -e git+https://github.com/abahde/DeepOBS.git@master#egg=DeepOBS

Is this bayes_opt package really necessary? It seems a bit tangential to the package's purpose (or at most optional).

Edit: It turns out that bayesian-optimization has relatively few requirements so this is not a big issue; perhaps just the docs need updating.

As an aside, it might be possible to suggest a single conda command that installs everything: conda install -c conda-forge seaborn matplotlib2tikz bayesian-optimization.
