Virgil,
Did you build matplotlib from source? If so, then chances are that one or
more backends were not built properly. This typically happens if you do not
have all the build dependencies.
Note, the build will not necessarily fail if some dependencies are missing
because the core portions of matplotlib still build successfully.
