only size-1 arrays can be converted to Python scalars

Python

I have such Python code:

import numpy as np 

import matplotlib.pyplot as plt 

def f(x): 

return np.int(x) 

x = np.arange(1, 15.1, 0.1) 

plt.plot(x, f(x)) 

plt.show()

And such error:

TypeError: only length-1 arrays can be converted to Python scalars

How can I fix it?

Your function is expecting a single value and you have passed an array instead. That is the reason you are getting this error. If you want to apply a function on each element of an array, you can use the vectorize method from numpy. Change your code to this.



import numpy as np


import matplotlib.pyplot as plt



def f(x):


return np.int(x)


f2 = np.vectorize(f)


x = np.arange(1, 15.1, 0.1)


plt.plot(x, f2(x))


plt.show()
