Hi, I'm getting the following error on the image that was last updated 4 months ago (info from the docker hub): --------------------------------------------------------------------------- NameError Traceback (most recent call last) /usr/lib/python3.6/site-packages/graph_tool/draw/graphviz_draw.py in graphviz_draw(g, pos, size, pin, layout, maxiter, ratio, overlap, sep, splines, vsize, penwidth, elen, gprops, vprops, eprops, vcolor, ecolor, vcmap, vnorm, ecmap, enorm, vorder, eorder, output, output_format, fork, return_string) 319 try: --> 320 if gv_new_api: 321 gvg = libgv.agopen("G".encode("utf8"), NameError: name 'gv_new_api' is not defined During handling of the above exception, another exception occurred: NameError Traceback (most recent call last) <ipython-input-4-3c9127bf2c6b> in <module>() 3 #output_size=(1920,1080), 4 #inline=True, ----> 5 output=home+'/g.png') /usr/lib/python3.6/site-packages/graph_tool/draw/graphviz_draw.py in graphviz_draw(g, pos, size, pin, layout, maxiter, ratio, overlap, sep, splines, vsize, penwidth, elen, gprops, vprops, eprops, vcolor, ecolor, vcmap, vnorm, ecmap, enorm, vorder, eorder, output, output_format, fork, return_string) 591 if has_layout: 592 libgv.gvFreeLayout(gvc, gvg) --> 593 libgv.agclose(gvg) 594 595 if len(ret) > 1: NameError: name 'libgv' is not defined --------------------------------------------------------------------------- Before I looked at the source code I tried the possible quickfix of 'pip install graphviz', which did not help. After looking at the source code I learned why it didn't help, yet dunno right out of the bat how to fix this error. Any ideas? Would greatly appreciate it! Kind regards, Juan
