Error when running "python run.py -e prototype_10" for Dendrites project

[leogagnon]

Hi,

I made no modification to the code and have followed all the instructions in the README.txt but I get the following error message :

(numenta) [leko@leko-pc permutedMNIST]$ python run.py -e prototype_10 --run_without_ray_tune True

Any idea what's happening?

Hi,I have a problem. ImportError: cannot import name '_TuneFunctionDecoder' from 'ray.tune.trial_runner' (E:\anaconda3\envs\dendrites\lib\site-packages\ray\tune\trial_runner.py) Do you know how to solve it? Thanks for your help.

Have you solved your problem? I have the same problem as you, okay? I want to know how to solve it.

The continual learning experiments should be run from the following repository, as this is a stable version of our implementation:

https://github.com/numenta/htmpapers/tree/master/biorxiv/going_beyond_the_point_neuron

We had provided a link to an unstable version, and that has been updated now. Sorry about that! If you follow the instructions in the README file in the link above, you should have no errors. Also, please don't use the flag run_without_ray_tune, just simply run python run.py -e prototype_10.

Firstly,ray==0.8.7 doesn't work on my computer. So I update it to ray==1.11.0. When I run 'python run.py -e prototype_10' , it also failed. And it prints:"ImportError: cannot import name '_TuneFunctionDecoder' from 'ray.tune.trial_runner' (E:\anaconda3\envs\nupic.research\lib\site-packages\ray\tune\trial_runner.py) I need your help. Thanks for your reply.
