lazyhaotao commented 2 years ago

Dear Developers， Thanks for your contributions. In rlbench_gym.py, when I tyied to generate two gym environments as follows: env1 = gym.make('reach_target-state-v0', render_mode='human') env2 = gym.make('reach_target-state-v0', render_mode='human') there have been some errors: qt.qpa.xcb: QXcbConnection: XCB error: 145 (Unknown), sequence: 177, resource id: 0, major code: 139 (Unknown), minor code: 20 Attribute Qt::AA_UseDesktopOpenGL must be set before QCoreApplication is created. WARNING: QApplication was not created in the main() thread. (process:18254): GLib-CRITICAL **: 16:19:58.776: g_main_context_push_thread_default: assertion 'acquired_context' failed We successfully make env1, but then the code stays at env2 all the time. Do you know how to resolve this problem? Thanks again.

Yes, but they need to be in separate processes. Please see here: https://github.com/stepjam/PyRep#running-multiple-pyrep-instances

Hi, Stephen, I tried to make two gym environments and saw your provided example, but it's a bit difficult for me to implement, could you show me more details about making two gym environments?
