Description

• Latest master
• Current python 3.8 packages (Arch Linux)
• clean venv, nuke ~/.cache/pip to ensure latest packages (should still respect locks)
• make install-dev on scenario-player
• Launch:

ValueError: greenlet.greenlet size changed, may indicate binary incompatibility. Expected 152 from C header, got 144 from PyObject

Probably related to gevent/gevent#1674 and some of the tons of duplicated issues reported there. Seems currently there's some incompatibilities around and specific packages pinning is required.

Expected Behavior

To work

The problem is that the latest released raiden version uses an older gevent. This leads to an older greenlet version with those incompatibilites.

I created #610 to improve this but for now the easiest fix is to install the raiden develop.

cd ../raiden
make install-dev
cd ../scenario-player
make install-dev
