Also trying with upgraded the scipy-1.5.3 as well. Still getting same error.

Thanks

Solution

After uninstall and install the scipy,

pip uninstall scipy 

press y, and after pip is done, type:

pip install scipy

Error seen:

"unistall and reinstall the scipy "ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts. We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default. tensorflow 2.3.0 requires scipy==1.4.1, but you'll have scipy 1.5.3 which is incompatible"

But, My actual Error was resolved

ImportError: cannot import name '_ccallback_c' from 'scipy._lib' (/usr/lib/python3.7/site-packages/scipy/_lib/__init__.py)
