Hello Jakub,
thanks for you report.

this is really weird! it seems that find is able to find the directories

$ find . -name __pycache__ -ls

./core/build/lib/pygraph/__pycache__
and to remove them, but it still emits those errors:

$ find . -name __pycache__ -exec rm -rf {} \;
find: `./tests/__pycache__': No such file or directory
find: `./dot/pygraph/__pycache__': No such file or directory
find: `./core/pygraph/__pycache__': No such file or directory
find: `./core/build/lib/pygraph/readwrite/__pycache__': No such file

find: `./core/build/lib/pygraph/algorithms/heuristics/__pycache__': No
such file or directory
find: `./core/build/lib/pygraph/algorithms/filters/__pycache__': No
such file or directory
find: `./core/build/lib/pygraph/algorithms/__pycache__': No such file
or directory
find: `./core/build/lib/pygraph/__pycache__': No such file or directory
$ find . -name __pycache__ -ls
$

even strace didn't reveal much. do you have any clue of what's going on?
