Error with scipy 1.8.0

I am getting an error with scipy 1.8.0

File "/home/brendan/python/TestVenv/lib/python3.8/site-packages/bayes_opt/util.py", line 65, in acq_max
if max_acq is None or -res.fun[0] >= max_acq:
TypeError: 'float' object is not subscriptable

The problem appears to be that in this new version of scipy, res.fun is returned as a number instead of an array. I haven’t yet found exactly where in scipy the change is. A fix may be as simple as adding an if statement to handle this case.

I’ll keep looking into it but for now I suggest limiting scipy installations to 1.7 or less.

hey all, just an update on this. I have permissions to manage this repository now and I have merged #303 into the main branch, which should resolve this error. However, I am still not able to release the code through pypi or conda forge. I will keep trying to get these permissions, but for now I would recommend installing directly from the master branch like this:

 pip install git+https://github.com/fmfn/BayesianOptimization

I have the same problem. I used pip install scipy==1.7 and it seems to work.
