crash when using pytorch #243

Closed superggb closed 3 years ago

superggb commented 3 years ago

Hello: I'm doing reinforcement experiment based on the example env script env_example . However when I created the environment and used reset() method then went to some pytorch codes , it crashed with some error as below:


/home/ggb/CoppeliaSim_Edu_V4_1_0_Ubuntu16_04/libcoppeliaSim.so.1(_Z11_segHandleri+0x28)[0x7fd1be15d0b8]

Something I want to mention is that I use conda environment and installed pytorch,tensorflow,baselines before. Before this error there is another error which told me the qt path is in the cv2 not in CoppeliaSim may because some imported library. I solved this by code below to change qt_path: '/home/ggb/miniconda3/envs/vrep/lib/python3.6/site-packages/cv2/qt/plugins' to:

os.environ['QT_QPA_PLATFORM_PLUGIN_PATH'] = /home/ggb/CoppeliaSim_Edu_V4_1_0_Ubuntu16_04

I don't know if this change will affect pytorch. I think maybe there are some conflicts such as threads between pyrep agent and my RL code. But I can't figure it out. So what's the problem?

BTW I used RL code modified from some gym envs, any differences should I notice?
