This might mean you are not passing it an absolute path, but
instead a relative one. Absolute paths (on Linux) are those
which start with a / (forward slash). Anything without that
will start from the current directory only.
But without actual examples of which paths are failing, as
Ben has asked for, we know nothing for certain.
Is it also possible that you are not having a problem with listdir()
at all, but with the values you are passing to os.path.isdir()?
You realize that os.listdir() returns names that are *relative*
to the path parameter you give it? So that if you then pass those
to isdir() you will get nothing useful if you don't first do
this instead? :
entry = os.path.join(path, entry)
