'Excel_dataset' object has no attribute 'reshape'

The error message 'Excel_dataset' object has no attribute 'reshape' means that you are trying to use the 'reshape' method on an object of type 'Excel_dataset', but this object does not have this method.

The 'reshape' method is usually used on NumPy arrays to change their shape. If you are trying to reshape a NumPy array that is stored in your 'Excel_dataset' object, you will need to extract the array first and then perform the reshape operation on it.

Here's an example:

import pandas as pd
import numpy as np

# Load data from Excel file
data = pd.read_excel('mydata.xlsx')

# Convert data to NumPy array
data_array = np.array(data)

# Reshape the array
reshaped_array = data_array.reshape((new_shape,))

If your 'Excel_dataset' object does not contain a NumPy array and you are still trying to use the 'reshape' method on it, you will need to check the documentation or the source code of the 'Excel_dataset' class to see what methods are available and how to use them.
