The following Python code is returning an error. What is wrong with the code? 

return 1.06 * min(np.sqrt(np.var(probs)), h) * len(probs)^(-1/5)

TypeError: ufunc 'bitwise_xor' not supported for the input types, and the inputs could not be safely coerced to any supported types according to the casting rule ''safe''

Are you trying to use len(probs) to the power of (-1/5)? If yes, the symbol "^" is not for the power operation in Python and hence you are getting the error. You need to use "**" for the power operation.

Replace the symbol "^" with "**" and it should fix the error.

return 1.06 * min(np.sqrt(np.var(probs)), h) * len(probs)**(-1/5)
