Python error TypeError range integer end argument expected got numpy float64

Question

I'm trying to run the following section of python code

for i in range(0, int(m)):
    y_pred = c + m * X[i]
    ss_t += (Y[i] - mean_y) ** 2
    ss_r += (Y[i] - y_pred) ** 2
    r2 = 1 - (ss_r/ss_t)
    print(r2)

I get the following error

TypeError: range() integer end argument expected, got numpy.float64.

Hi @Kashish, try something like this:

for i in range(0, int(m)):
    y_pred = c + m * X[i]
    ss_t += (Y[i] - mean_y) ** 2
    ss_r += (Y[i] - y_pred) ** 2
    r2 = 1 - (ss_r/ss_t)
    print(r2)
