Typeerror: 크기가 1인 배열만 Python 스칼라로 변환할 수 있습니다. - 솔루션

In the first method, we use the .vectorize function. The .vectorize function is essentially a for loop that takes in an array and returns a single numpy array. Using this method we iterate over the array x and return a single value. Thus we do not encounter the "only size-1 arrays can be converted to Python scalars" typeerror.

import numpy as ny
import matplotlib.pyplot as matplot
xcord = ny.arange(1, 5, 2.5)
ycord = ny.vectorize(ny.int)
matplot.plot(xcord, ycord(xcord))
matplot.show()

As you can see we no longer need to define a function as we have used the .int function inside the .vectorize function, which loops through the array and returns a single array that is accepted by the .int function.

Another method I came across utilizes the .astype method, this method casts the array into a specified type in our case int. Although this method works, I personally recommend the first solution as this method casts a string into an int which is not a desirable method.

import numpy as ny
import matplotlib.pyplot as matplot

def ycord(xcord):
    return xcord.astype(int)

xcord = ny.arange(1, 5, 2.5)
matplot.plot(xcord, ycord(xcord))
matplot.show()

These are two solutions that can be used when faced with the Typeerror: Only size-1 arrays can be converted to Python scalars error.
