Cannot reproduce README example: KeyError: '__file__'

[nestorSag]

I try to run the examples from the repo's README file but I get an error. The version of dload is 0.6, python is 3.6.9 and the requests library is 2.23.0; OS is Ubuntu 18.04

import dload
dload.save('https://upload.wikimedia.org/wikipedia/commons/thumb/d/d3/Albert_Einstein_Head.jpg/800px-Albert_Einstein_Head.jpg', '~/einstein.jpg')  
Traceback (most recent call last):
