5 years ago Thanks for trying the software! We did notice problems with OpenGL stimulus display on some Linux configurations, it should be switched off if causes problems. However, this should have no influence on offline tracking. The numpy RuntimeWarning is nothing to worry about, it doesn't cause crashes.
What do you mean exactly by no tracking happens? If you follow the steps at http://www.portugueslab.com/stytra/userguide/7_offline.html which step fails for you? Could you please attach the outputs of conda list and conda info commands? We can set up a linux environment next week to check for any further issues.

Hello there, amazing job you did with the program!! I'm trying to use the offline tracking feature (tail) and I'm facing an error. The GUI loads ok and the video to track also but then no tracking happens and after a while the console shows :
(stytra) acer@swift:~$ /home/acer/anaconda3/envs/stytra/lib/python3.7/site-packages/numpy/lib/function_base.py:1520: RuntimeWarning: invalid value encountered in greater _nx.copyto(ddmod, pi, where=(ddmod == -pi) & (dd > 0)) /home/acer/anaconda3/envs/stytra/lib/python3.7/site-packages/numpy/lib/function_base.py:1522: RuntimeWarning: invalid value encountered in less _nx.copyto(ph_correct, 0, where=abs(dd) < discont)I'm on Ubuntu 16.04 or 19.04 (same error for both versions) and all conda packages up to date.
Thanks!
--EDIT-- Im getting a new error in one of my installations.
