ImportError: cannot import name 'return_future'

Error reproduced below: Set up virtual environment with bokeh version 0.13.0, it was working but I reinstalled my environment the same way as before: ‘python3 -m venv [environment name]’ but I receive the error below. Normally I would run the command below for access from web but I used just ‘bokeh serve percpetron.py’ for simplicity and troubleshooting.

bokeh serve perceptron_plot.py --port XXXX --prefix=/perceptron_plot --allow-websocket-origin=www.website.com

Hi,

Tornado 6.x (released a few days ago) removed tornado.concurrent AFAICT, which means it is incompatible with Bokeh 0.13. You will have to either:

* upgrade to a newer Bokeh version (highly recommend), or
* downgrade to an older Tornado version

Thanks,

Bryan

Yup, I was already about to close this discussion… indeed, I downgraded to older tornado version and it worked.
