adv_ex is already a numpy array, so you can’t call .numpy() again on it (which is a tensor method).
Store adv_ex as a tensor or avoid calling numpy on it:
adv_ex = perturbed_data.squeeze().detach().cpu()
adv_examples.append( (init_pred.item(), final_pred.item(), adv_ex) ) Answer from ptrblck on discuss.pytorch.org

Thanks!. My bad, I haven’t noticed that it is already called.
cnt = 0
plt.figure(figsize=(8,10))
for i in range(len(epsilons)):
for j in range(len(examples[i])):

The problem is that train_test_split(X, y, ...) returns numpy arrays and not pandas dataframes. Numpy arrays have no attribute named columns
If you want to see what features SelectFromModel kept, you need to substitute X_train (which is a numpy.array) with X which is a pandas.DataFrame.
selected_feat= X.columns[(sel.get_support())]
This will return a list of the columns kept by the feature selector.
If you wanted to see how many features were kept you can just run this:
sel.get_support().sum() # by default this will count 'True' as 1 and 'False' as 0

because this :
X = df.iloc[:,:24481].values
y = df.iloc[:, -1].values
you should remove .values or make extra X_col, y_col like that
X_col = df.iloc[:,:24481]
y_col = df.iloc[:, -1]

How to Fix: ‘numpy.ndarray’ object has no attribute ‘append’ - GeeksforGeeks
November 28, 2021 - The output is pretty explanatory, the NumPy array has a type of numpy.ndarray which does not have any append() method. Now, we know that the append is not supported by NumPy arrays then how do we use it? It is actually a method of NumPy and not its array, let us understand it through the example given below, where we actually perform the append operation on a numpy list. ... values: numpy array or value: These values are appended to a copy of arr.

Write a function to calculate accumulated GPA (omit grade <5).
