aesara.tensor.bincount(x, weights=None, minlength=None, assert_nonneg=False)[source]#

Count number of occurrences of each value in an array of integers.

The number of bins (of size 1) is one larger than the largest value in x. If minlength is specified, there will be at least this number of bins in the output array (though it will be longer if necessary, depending on the contents of x). Each bin gives the number of occurrences of its index value in x. If weights is specified the input array is weighted by it, i.e. if a value n is found at position i, out[n] += weight[i] instead of out[n] += 1.

Parameters:

  • x – A one dimensional array of non-negative integers

  • weights – An array of the same shape as x with corresponding weights. Optional.

  • minlength – A minimum number of bins for the output array. Optional.

  • assert_nonneg – A flag that inserts an assert_op to check if every input x is non-negative. Optional.

  • versionadded: (..) – 0.6:
