Plotly causes errors in utilities.py

[BJWiley233]

Hi,
When I try to run plotly output with the heatmap I get error in utilities.py TypeError: 'map' object is not subscriptable because you are trying to subscript a map which is not allowed in Python 3. We need to update this if using Python 3 to C = list(map(np.uint8, np.array(cmap(k * h)[:3]) * 255))

In addition may want to look at matplotlib deprecation warning at correlation.py:306

MatplotlibDeprecationWarning:

You are modifying the state of a globally registered colormap. In future versions, you will not be able to modify a registered colormap in-place. To remove this warning, you can make a copy of the colormap first. cmap = copy.copy(mpl.cm.get_cmap("jet"))

Also with the scatterplot for plotly you can no longer set at line 424 in correlation.py the trace using the code fig['data'] = data. You have to use the add_traces() function as indicated at link below as in fig.add_traces(data)
