scikit-learn kernel density not working with 1-D array

I'm trying to compute kernel density estimation using scikit-learn, and it's not working for 1-D array
Suppose this is the array
import numpy as np
from sklearn.neighbors import KernelDensity
df = [11,22,1,5,22,68,10,22,10.5,33,221,45,22,...................]
kde = KernelDensity(kernel='gaussian', bandwidth=0.75).fit(df)
ValueError: Expected 2D array, got 1D array instead:
array=[ 11. 22. 1. 5. 22. 68. 10. 22. 10.5 33. 221. 45.
22. ].
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 tried to reshape the array
kde = KernelDensity(kernel='gaussian',bandwidth=0.75).fit(np.array(df).reshape(-1,1))
# or
kde = KernelDensity(kernel='gaussian',bandwidth=0.75).fit(np.array(df).reshape(1,-1))
But it's not working either.

When you say, "it's not working," what do you mean? What error are you getting? Both commands execute without error on my setup.

Now it's giving me this : Expected 2D array, got scalar array instead

if you reshape the array separately, what does it look like? Can you show your output from the reshape commands? When you say "it's giving me this," what is "it"? Python? Numpy? Scikit-lean? Your computer? Can you paste the error message and traceback?

When you say, "it's not working," what do you mean? What error are you getting? Both commands execute without error on my setup.
