When I try to plot a simple heatmap (inspired by this) like the following I get an empty heatmap.
import holoviews as hv hv.extension('bokeh') data = [(chr(65+i), chr(97+j), i*j) for i in range(5) for j in range(5) if i!=j] hv.HeatMap(data).sort()
This issue also seems to affect the example in the documentation. In the reference gallery overview the heatmap image is empty like the one in my example above.
When I download the notebook from the example I get this error:
I can't even delete the file from within jupyter-lab. I never had this issue with any other file before.
