how can i solve this error?

for this error :

ValueError Traceback (most recent call last)
Cell In[40], line 2
1 # Convert your list (eeg_O1_data) into a NumPy array
----> 2 eeg_O1_data_array = np.array(eeg_O1_data)

ValueError: setting an array element with a sequence. The requested array has an inhomogeneous shape after 1 dimensions. The detected shape was (76,) + inhomogeneous part.

It happens because t the elements within the eeg_O1_data list are not of uniform shape or type, which is causing the issue when I try to convert the list into a NumPy array.

There are 2 options to solve :partying_face:
1- to pad with zeros.
2- Create a List of Arrays: If preserving the original shapes of the arrays is important, I can keep them in a list. This will allow you to work with them individually without converting them into a single large array.

I want to preserve the original shapes and in the same time to create a raw object I need to convert the data into numpy array.

Please Advice me on this !!

this solution is make sense?

To me, it sounds like the fact that your EEG data is inhomogeneous is the problem you’ll need to solve. Why is that data inhomogeneous in the first place? Isn’t every channel sampled at the same frequency?
