strange term `random.choices`

[amiltonwong]

Hi, @bfortuner ,

I found a strange term random.choices in this line. There is no random.choices (link) . Is it a typo or have special meaning?

There is no numpy.random.choices, but there is arandom.choices. See link

It's written in Python 3. Change that line to return ''.join(random.choice(string.ascii_uppercase + string.digits)) and run it via Python 2.

random.choices is available in python 3.6. i think you can use random.sample instead. ''.join(random.sample(string.ascii_uppercase + string.digits, k=n))

But sample gives elements without replacement whereas choices gives elements with replacement. Not sure if this affects the prediction accuracy of the model though!
