Hi, According to log there seems to be an exception related to django core and your project setup (django.core.exceptions.SynchronousOnlyOperation) and not django-ptpython. I can't regenerate exception unless you provide more information. nonetheless you can give it a try with a simple model and then import particular models instead of importing all objects of the module.
