I have been using export_png (and export_svgs) a lot lately and everything worked like a charm until I updated to Bokeh 1.3.0.
Running the following example returns these errors:
WARNING:bokeh.io.export:There were browser warnings and/or errors that may have affected your export WARNING:bokeh.io.export:ReferenceError: Can't find variable: Set
import numpy as np import bokeh.plotting as bp from bokeh.io import export_png, export_svgs x = np.linspace(0, 2) y = np.sqrt(x) fig = bp.figure(width=700, height=300) fig.circle(x, y) export_png(fig, "test.png")
Anyone else having issues with export_png since Bokeh 1.3.0?
(Under 1.2.0 the same script returns no error.)
