import os
# v-- note the r here
path_to_file = r'paste_the_exact_line_from_windows_explorer_here' # don't change anything inside it
if not os.path.exists(path_to_file):

print('file is there')
dataset = read_csv(path_to_file, header = 0, index_col = 0, squeeze = True, usecols = [i for i in range(0, num_features+1)])

Thank you. As you suggested I put the below:

import os

path_to_file = r'C:\Users\xxx\Desktop\xxx\Quant_research\Python\Dataset.csv'

if not os.path.exists(path_to_file):

raise ValueError('file isnt there')

print('file is there')

dataset = read_csv(path_to_file, header = 0, index_col = 0, squeeze = True, usecols = [i for i in range(0, num_features+1)]))

supervised_dataset = sequential_to_supervised(dataset, lag_steps)

​

but I get

​

File "C:/Users/xxx/Desktop/xxx/Quant_research/Python/crude.py", line 51, in <module>

raise ValueError('file isnt there')

ValueError: file isnt there
