Dec 25, 2016 · 35. TypeError: type numpy.ndarray doesn't define round method. You tried applying round to numpy.ndarray. Apparently, this isn't supported. Try this, use numpy.round: rounded = [numpy.round(x) for x in predictions] x is numpy array. You can also try this: rounded = [round(y) for y in x for x in predictions]
Apr 23, 2022 · 2. You are only returning price in your function if type == 'P'. But for the branch type == 'C' there is no return statement. Maybe you mean: try: if type == "C": price = S*norm.cdf(d1, 0, 1) - K*np.exp(-r*T)*norm.cdf(d2, 0, 1) elif type == "P":
Oct 29, 2012 · You can see that PostgreSQL is expanding it in the output). You must cast the value to be rounded to numeric to use the two-argument form of round. Just append ::numeric for the shorthand cast, like round(val::numeric,2). If you're formatting for display to the user, don't use round.
Jan 31, 2009 · There is a round() function, also fround(), which will round to the nearest integer expressed as a double. But that is not what you want. I had the same problem and wrote this: #include <math.h> double db_round(double value, int nsig) /* ===== ** ** Rounds double <value> to <nsig> significant figures.
More than likely some of the labels you have in y_train are actually strings instead of numbers.sklearn and xgboost don't require the labels to be numeric.

The documentation for the round () function states that you pass it a number, and the positions past the decimal to round. Thus it should do this: n = 5.59. round(n, 1) # 5.6. But, in actuality, good old floating point weirdness creeps in and you get: 5.5999999999999996. For the purposes of UI, I need to display 5.6.
