TTTFS dyn thresh and TTFS corrective not working about snn_toolbox

@rbodo have you faced this issue before? I don't what else I should try to find the root cause for this

Hi, I haven't seen this error before. And tbh I don't really see how it fails - the error message from the h5py library does not seem to offer any explanation. Was there nothing else in the output?

You said you are using the dev version, but curiously the line numbers don't seem to match: The stack trace points to line 255 for the save method, but in the repo it's on line 253. Might be nothing, but can you confirm there has been no relevant modification to the source code?

As to the actual problem: Since we are calling the standard keras.save method here, I would guess that the keras version you have installed is incompatible with the custom SNN model properties which we are trying to save. If that is indeed the reason, ideally one would try to figure out which ones are causing the issue and bring them up to date with keras. Alternatively, you could try downgrading keras (see here for an old version list, perhaps you could start from there).
