Runtime Warning - Greenlet.greenlet size changed??

Question

I am running a module which can be found here: https://github.com/danieliu/play-scraper

My code inside python file is as follows:

import play_scraper

print(play_scraper.collection(
      collection='TOP_FREE',
      category='COMMUNICATION',
      results=5,
      page=1))

I do not quite follow the error message in the terminal and I am unsure on how to or where to search to proceed forward.

    import play_scraper

Any help would be greatly appreciated.

Answer 1

For those getting the below error message. You are likely experiencing issues caused by library updates from gevent & greenlet.

RuntimeWarning: greenlet.greenlet size changed, may indicate binary incompatibility. Expected 144, got 128
  return f(*args, **kwds)

see below for more detail. https://github.com/gevent/gevent/issues/1260

The reported compatible versions among greenlet gevent gunicorn are (worked for me)

gunicorn==19.9.0
gevent==1.3.4
greenlet==0.4.13

There are others reporting below might also work as well (I have not tested this).

gevent==20.9.0
greenlet==0.4.17

Answer 2

For windows it get sovled by using : pip install greenlet==0.4.16
