Hi guys, When I run python test_sim.py, I get the following error:

Traceback (most recent call last): File "test_sim.py", line 2, in <module> from sim_env import SimEnv File "/home/hc/dextairity/sim_env.py", line 7, in <module> import pyflex ImportError: /home/hc/dextairity/PyFlex/bindings/build/pyflex.cpython-36m-x86_64-linux-gnu.so: undefined symbol: cudaSetupArgument

Can anyone help me??

I got the same issue. I'm running the program on Ubuntu 20.04

I'm thinking maybe CUDA is not installed

I have figured out where the error was. I forgot to replace the anaconda3 directory when starting the Nvidia docker container at

nvidia-docker run \
	-v $FLINGBOT_PATH:/workspace/flingbot\
	-v /path/to/your/anaconda3:/path/to/your/anaconda3\
	--gpus all --shm-size=64gb  -d -e DISPLAY=$DISPLAY -e QT_X11_NO_MITSHM=1 -it flingbot

I am also having this issue.

@canhe173 Running the docker container attached instead of detached (removed the -d tag in the docker run command) worked for me. Make sure to stay in the flingbot conda environment by using conda activate flingbot again after starting the docker container. Then exit the docker container using exit before evaluating or training.

Have you run through the author's training code yet
