Getting an error when running myBopt.plot_acquisition() from tutorial

[fedeotto]

Just by running the tutorial on my notebook I get an error when it comes to run

myBopt.plot_acquisition()

The error:

I had a same error, and successfully fixed as follows. This problem would be caused by the change of matplotlib function _process_unit_info(). For me, downgrading matplotlib to 3.1.3 ( pip install matplotlib==3.1.3) works.

Hi,

I downgraded the verison to 3.1.3 as describe above. But then, it started to show another error.

here is an error code.

can anyone tell what is wrong with the code below?

domain = [{'name': 'var_1', 'type': 'continuous', 'domain': (-5,4)}] myBopt_1d = BayesianOptimization(f=obj_func, domain=domain) myBopt_1d.run_optimization(max_iter=5) myBopt_1d.plot_acquisition()

Hi, just in case anyone is still looking for ways to resolve this. I tried this suggestion of using matplotlib 3.1.3, and it worked! Here are the steps I did in my Jupyter. My computer has Python 3.9 and I think matplotlib 3.1.3 needs Python 3.6.

1. Create a new environment with python 3.6 in it. (this helped)
2. Activate this new environment
3. I installed a jupyterlab for this new environment (jupyter notebook also works I guess)
4. I installed all the packages again like GPyOpt, numpy and pandas for my own use.
5. To check if it has Python 3.6, run a cell with the following:

import sys print(sys.version)

I finally have the "opt.plot_acquisition()" working!
