ImportError: cannot import name 'minimize' from 'scipy.optimize' (unknown location) #81

Closed SSMK-wq closed 1 year ago

I am using python 3.8.8 in windows 10 with btyd 0.1b3.

While my btyd package is installed successfully, I get the below error when I try to import the btyd package in my jupyter notebook

ImportError                               Traceback (most recent call last)

How to import btyd package successfully without any error?

my pip show command returns the below output

When I degrade the scipy to 1.6.1, I get the below warning and error in jupyter notebook

Closing this issue as a fresh install after clean up of environment solved the issue. Not sure whether it is the best way to solve this problem but solved for now. So, closing this
