I’m trying to run the first code section in the documentation of the Upload component: https://dash.plot.ly/dash-core-components/upload
Uploading to the running example on the page does nothing.
When I run the example locally and upload a image file, I get “UnboundLocalError: local variable ‘df’ referenced before assignment”.
The full trace is:
Traceback (most recent call last):
