Here's a minimal way to reproduce the problem:

$ mkdir __pycache__
$ find . -name __pycache__ -exec rm -rf {} \;
find: ‘./__pycache__’: No such file or directory

The trouble is that is that find tries to descend to the directory that 
has just been deleted, which of course doesn't work. Appending -prune to 
the find command-line fixes the problem:

$ mkdir __pycache__
$ find . -name __pycache__ -exec rm -rf {} \; -prune
$ echo $?
0
