I followed the installation instructions:
pip install dash==0.35.1 # The core dash backend
pip install dash-html-components==0.13.4 # HTML components
pip install dash-core-components==0.42.1 # Supercharged components
pip install dash-table==3.1.11 # Interactive DataTable component (new!)
And successfully ran some of the samples. I then tried to run the button click example and thereafter get the dreaded error: “Dash was not successfully imported. Make sure you don’t have a file named
‘dash.py’ in your current directory.”
I fully re-installed the environment and it worked for a bit. Then, I think, I ran the button click example again, and it failed again.
There are many prior references to this error message but the solutions seem to involve upgrading.
Dash seems to be a beautiful creation. I would appreciate any ideas on fixing the problem or how to debug the situation.
Addendum
import dash # this import fails
Using python 3.6 and pycharm
Tried downgrading dash to 0.30 - no change
Removed dash from venv environment and reinstalled with pip - no change
