Apologies, I'm not sure what else to try and I don't have a Matlab license to try and reproduce.

Hi @suixiaodan, I think it is complaining because we check if `self.__matlab` is set before actually setting it. I'll push a fix.

Please try `pip install -U matlab_kernel` to pick up 0.16.5.

What is the output of `python -m matlab_kernel.check`?

Drat, there was a typo in `check.py`, can you please run `python -m pip install -U matlab_kernel` and then run `python -m matlab_kernel.check` again?

Thanks @IanSudbery, I actually forgot to remove `setup.py`, I've switched to `flit` for development.

Seconded :smile:

Hi @mjbright, does that same code work for you in a regular python kernel?

That is a real bummer that a `StringIO` object would not have the same interface as a file object.

That is odd, we're getting that path from the `__file__` attribute of [kernel.py](https://github.com/Calysto/octave_kernel/blob/0ae34050c2e6a2cbf45b9cdb1a69762fece9e081/octave_kernel/kernel.py#L332)
