I saw some places where Incorrect Padding error was resulted from binascii module and it was mostly when the string you pass has some extraneous white-space characters.

>>> import binascii
>>> binascii.a2b_base64('a')
Traceback (most recent call last):
  File "", line 1, in 
binascii.Error: Incorrect padding

In your case, it the various properties you set for your env object. Do something like this for your key file location and see if that works.

filelocation = os.path.join(WORK,'aws/myproject.pem')
env.key_filename = [filelocation]
