[Matplotlib-users] matplotlib: no output with Agg - TkAgg - Qt5Agg -- stuck at ttconv.so

[Benjamin Root]

The error for Qt5 is a bug that has very recently been fixed. I am pretty
sure it is in v1.5.3. (Well... not exactly fixed, more that it won't crash
the interpreter). It does seem like you are making it further than you were
before. It would be good to see the traceback from the Qt5 failure, and to
know which version of matplotlib you are using.
