server selects Runners from list and sends model

[alex80]

My goal is the server selects the number of runners from a list list1=[7, 9, 5, 0, 8] instead of integer value (5) to send to those runners only (7, 9, 5, 0, 8).

This is my Code which is works:

for runner in random.sample(runners, k=self.sample_size):
r_model = runner.optimise(self.intercept_, self.coef_, self.runner_hyperparams)

hyperparams = {
        'n_runners': 10,
        'sample_size': 5,
        'rounds': 1,
        'combine': 'weighted', # or 'mean'
        'partition_params': {
            'scheme': 'uniform'
        },
        'runner_hyperparams': {
            'epochs': 10,
            'lr': 0.15,
            'batch_size': 0
        }
    }

but when i trying to send to a list1,

hyperparams = {
    'n_runners': 10,
    'sample_size':list1,
    'rounds': 1,
    'combine': 'weighted', # or 'mean'
    'partition_params': {
        'scheme': 'uniform' # stratified, non-iidness, noise injection etc.
    },
    'runner_hyperparams': {
        'epochs': 10,
        'lr': 0.15,
        'batch_size': 0
    }
}

I am getting an IndexError, and not sure why?

Error:
TypeError: '<=' not supported between instances of 'int' and 'list'

In random.sample(), k has to be a number. You're feeding it a list. If you want to feed it a number equal to the length of the list, convert it first.

for runner in random.sample(runners, k=len(self.sample_size)):

If for some reason sample_size is equal to runners, then just use random.shuffle() instead.
