Hello, and thank you for the report! This is a bug in Rope. Sadly, the current maintainers of Rope are pretty explicit in that they do not care about fixing these types of bugs, so there is very little Elpy can do. The next release of Elpy will ignore all errors thrown by Rope, which should fix this problem, too.

Hello. Thanks a lot.

[emacsway]

As I see, there is used rope in Python3. Rope does not support python3 currently, just use rope_py3k

Yes it is venv with Python3 inside. Thank you for wise suggestion.
