Are there different versions of pillow?

[buran]

Please, tell me what version of reportlab do you have?
In their latest version they have this line:

if getattr(Image,'VERSION','').startswith('1.1.7'): im.load()

They reflected the change in pillow in their code.
In your traceback it's a different line - from an older version:

Error:
if Image.VERSION.startswith('1.1.7'): im.load()

forget about what I said to downgrade pillow to 5.4.1. Just upgrade reportlab to latest version.
