Python--calculate normalized probability of a value given a list of samples

So, as the title says, I'm trying to calculate the probability of a value given a list of samples, preferably normalized so the probability is 0<p<1. I found this answer on the topic from about 6 years ago, which seemed promising. To test it, I implemented the example used in the first reply (edited for brevity):

import numpy as np
from sklearn.neighbors import KernelDensity
from scipy.integrate import quad


# Generate random samples from a mixture of 2 Gaussians
# with modes at 5 and 10
data = np.concatenate((5 + np.random.randn(10, 1),
                       10 + np.random.randn(30, 1)))

x = np.linspace(0, 16, 1000)[:, np.newaxis]

# Do kernel density estimation
kd = KernelDensity(kernel='gaussian', bandwidth=0.75).fit(data)

# Get probability for range of values
start = 5  # Start of the range
end = 6    # End of the range

probability = quad(lambda x: np.exp(kd.score_samples(x)), start, end)[0]

However, this approach throws the following error:

Traceback (most recent call last):
  File "prob test.py", line 44, in <module>
    probability = quad(lambda x: np.exp(kd.score_samples(x)), start, end)[0]

ValueError: Expected 2D array, got scalar array instead:

Reshape your data either using array.reshape(-1, 1) if your data has a single feature or array.reshape(1, -1) if it contains a single sample.

I'm not sure how to reshape the distribution when its already inside the lambda function, and, in any case, I'm guessing this is happening because Scikit-Learn has been updated in the 6 years since this answer was written. What's the best way to work around this issue to get the probability value?

Thanks!
