Issue
I have a Pandas dataframe with 785
columns (784
columns and 1
column as a label).
I wanna use CNN to train a model on it, therfore I should convert each row if the dataframe to "image": (28x28x1)
(28x28=784), so a new dataframe will contain only 2 columns.
How can I can it?
Solution
Following code is an example of 4 columns and a label.
import numpy as np
import pandas as pd
csv_path = './example.xlsx'
df = pd.read_excel(csv_path)
df_new = pd.DataFrame(columns=['Column', 'label'])
for i, row in df.iterrows():
a = []
for j, column in row.iteritems():
if j == 'label':
label = column
break
a.append(column)
img = np.array(a).reshape(2, 2)
label = column
df_new.loc[i] = [img, label]
df_new.to_csv('result.csv', index=False)
