Thanks for reporting. This is a duplicate of many previous errors, e.g. #5673. As the error message states, Jedi is only compatible with parso 0.1.0, not 0.1.1. Therefore, you can update jedi to the latest version with conda update jedi ; you can also downgrade to parso 0.1.0 with e.g. conda install parso=0.1.0 (or similar with pip, if you use that instead), and you can close this issue.
