'thresh' parameter when using DiehlAndCook2015 model?

[rafaelblevin821]

Hi, I am trying to change the thresh value for DiehlAndCook2015 model, but it does not seem to be a callable argument.

I added it to the argument parsers in the 'models' file, hoping this would solve the problem, but I still get the following message:

usage: sprvsd_cancer_weights_sum_sam_00.py [-h] [--seed SEED] [--n_neurons N_NEURONS] [--n_epochs N_EPOCHS] [--n_train N_TRAIN] [--n_test N_TEST] [--n_clamp N_CLAMP] [--exc EXC] [--inh INH] [--theta_plus THETA_PLUS] [--time TIME] [--dt DT] [--intensity INTENSITY] [--progress_interval PROGRESS_INTERVAL] [--update_interval UPDATE_INTERVAL] [--train] [--test] [--plot] [--gpu] [--device_id DEVICE_ID] sprvsd_cancer_weights_sum_sam_00.py: error: unrecognized arguments: --thresh 50

I am sure I must be missing something...

Any help on this would be greatly appreciated.

I am not familiar with the script sprvsd_cancer_weights_sum_sam_00.py, The error message seems to come from that script.

In any case, the last updated the DiehlAndCook2015 to added two more parameters inh_thresh default 40.0 and exc_thresh default -52.0 to accommodate the two neuron population (inhibitory and excitatory).

@Hananel-Hazan thanks.

inh_thresh and exc_thresh aren't in the bindsnet version 0.3.1 I am using. Is there any way to update without causing problems?

I can add the extra lines into the DiehlAndCook2015 model in models.py, but I'm not sure if any other files also need to be changed...?

Depend how you are using BindsNET. If you installed using the pip install command you only need to run again pip install -U git+https://github.com/BindsNET/bindsnet.git . If you use the development installation, just update the repository and you all set.

I think I have it working by adding the inh_thresh and exc_thresh to models.py and adding the argument parsers. Any further issues, I will update.

Thanks @Hananel-Hazan
