Unable to find the Python PIL library.Google App Engine

Question

Installed the Google App Engine SDK.Python 2.6 perfect. Wanted to go into images, and test locally.Installed PIL

Installed Python, then ran the PIL install, worked this time.

Things seemed good, but trying to do localhost image manipulation gives:

"NotImplementedError: Unable to find the Python PIL library.  Please
 view the SDK documentation for details about installing PIL on your system."

System : winxp

Answer 1

I took a while to get PIL working. Mainly because I forgot to tell app engine to load it in the yaml file:

 libraries:
     - name:    PIL
     version: 1.1.7

Maybe this step is obvious, but I did not see it documented well on google documentation and I found all kinds of messages here stating that PIL was not available on app engine. I want to confirm that PIL is running on app engine.

Answer 2

We're probably going to need more information, so here are some questions and things to try.

How are you trying to access the PIL? Are you trying to use the google.appengine.api.images module, or PIL directly? It sounds like the former, but it's not clear.

Did you follow the App Engine instructions?

Post code, if you can.

Perhaps the most important thing to try: see if you can use PIL from a non-App Engine script. Just write a quick Python script that accesses it and see how that goes. Something like:

import Image
im = Image.open('filename.png')
im.show()

If that doesn't work, it's not surprising that Google App Engine wouldn't work with PIL.
