没有名为“ PIL”的模块，但已满足要求

Question

I'm trying use Image from PIL but when i run my script file it says,

Traceback (most recent call last): File "script.py", line 12, in from PIL import Image ModuleNotFoundError: No module named 'PIL'

But i can see that Pillow 5.0.0 is install when i list all modules using pip list.

i have already searched for solutions but most of them point out to install Pillow, which i already have! what am i doing wrong?

I have a script file to download images from internet it uses Pillow, i have tried all known solutions but they all point to install pillow again and again.

import sys, os, multiprocessing, urllib, csv
from io import StringIO
from PIL import Image


def ParseData(data_file):
 csvfile = open(data_file, 'r')
 csvreader = csv.reader(csvfile)
 key_url_list = [line[:2] for line in csvreader]
 return key_url_list[1:]  # Chop off header


def DownloadImage(key_url):
 out_dir = sys.argv[2]
 (key, url) = key_url
 filename = os.path.join(out_dir, '%s.jpg' % key)

if os.path.exists(filename):
 print('Image %s already exists. Skipping download.' % filename)
 return

try:
 response = urllib2.urlopen(url)
 image_data = response.read()
except:
 print('Warning: Could not download image %s from %s' % (key, url))
 return

try:
 pil_image = Image.open(StringIO(image_data))
except:
 print('Warning: Failed to parse image %s' % key)
 return

try:
 pil_image_rgb = pil_image.convert('RGB')
except:
 print('Warning: Failed to convert image %s to RGB' % key)
 return

try:
 pil_image_rgb.save(filename, format='JPEG', quality=90)
except:
 print('Warning: Failed to save image %s' % filename)
 return


def Run():
 if len(sys.argv) != 3:
  print('Syntax: %s <data_file.csv> <output_dir/>' % sys.argv[0])
  sys.exit(0)
 (data_file, out_dir) = sys.argv[1:]

if not os.path.exists(out_dir):
 os.mkdir(out_dir)

key_url_list = ParseData(data_file)
pool = multiprocessing.Pool(processes=50)
pool.map(DownloadImage, key_url_list)


if __name__ == '__main__':
 Run()

Asked my friend for help on this matter as he's a python dev! So he said anaconda latest on windows is unstable and recommended to use anaconda on Linux. So i tried in Fedora workstation and then i didn't face any problem.
