Tab Completion Failed in Python 6.0.0

See original GitHub issue

I have a problem while trying to do a tab completion in IPython. Specifically, if I write from sci<tab> then this error appears

After it repeats many more times, the following appears:

Again repeating over and over again What could be the problem? I’m not sure how to try to fix this.

Thanks in advance!

@mingwandroid Thank you. There was an update: jedi:0.10.2-py36_1 --> 0.10.2-py36_2. After updating, everything is all right. No error occurs with tab completion.

Yeah, we are missing the grammar*.txt files here, not sure why, I’ve assigned the bug over at https://github.com/ContinuumIO/anaconda-issues/issues/1725 to myself.
