ValueError: max() arg is an empty sequence

Hi,

I tried your toolbox using my trained model and your broden dataset. I ran rundissect.sh, and I finally got this:

Traceback (most recent call last):
File "src/report.py", line 425, in
verbose=True)
File "src/report.py", line 45, in generate_html_summary
save=ed.filename('html/' + barfn))
File "/home/cc/NetDissect-release1/src/bargraph.py", line 106, in bar_graph_svg
barheight, barwidth, show_labels, filename)
File "/home/cc/NetDissect-release1/src/bargraph.py", line 110, in make_svg_bargraph
unitheight = float(barheight) / max(heights)
ValueError: max() arg is an empty sequence

Do you know how to fix this problem? Thank you.
b.t.w. there is no html folder under NetDissect.
