Ap_uniform_sampler() Missing 1 Required Positional Argument: 'high' In Ray Tune Package For Python

I am trying to use the Ray Tune package for hyperparameter tuning of a LSTM implemented using pure Tensorflow. I used the hyperband scheduler and HyperOptSearch algorithms for this

Solution 1:

Looks like simple typographical error here:

'lstm_size': hp.uniform('lstm_size', [8,16,32,64,128]),

It seems that you wanted lstm_size to be chosen from the list supplied. In that case you need to use hp.choice here too, just like you used for all the other parameters below 'lstm_size'.

'lstm_size': hp.choice('lstm_size', [8,16,32,64,128])
