TypeError: metaclass conflict

[lineojcd]

hi, followed the instruction tightly, I have successfully installed habitat-sim(v0.2.0), habitat-lab(v0.2.0) and rosxhabitat. python3.6, gym version is 0.26.2

habitat-sim(v0.2.0) is installed from conda

Then I ran this command, and got the error below: (rosxhab) arcs@ARCS:~/catkin_ws/src/ros_x_habitat$ python src/scripts/eval_and_vis_habitat.py --input-type rgbd --model-path data/checkpoints/v2/gibson-rgbd-best.pth --task-config configs/setting_2_configs/pointnav_rgb-mp3d.yaml --episode-id -1 --seed-file-path seeds/2_seeds.csv --log-dir log-dir --make-maps --map-dir map-dir --make-plots --plot-dir plot-dir

Can you help me out?

@lineojcd I'm also having the same problem, have you been to find a solution?

[ericchen321]

Hello @PhilipAmadasun, thanks for reaching out! I suspect the error was caused by package versioning, since Habitat's requirements.txt's generally specify min version's but not max verion's, and I guess as time passes by old API calls no longer work.

I've updated requirements.txt and Step 1-5 of the instruction. Could you reinstall those packages + Habitat Lab + Sim and see if things work? Also note that I don't have the machine with a working conda env next to me so I'm not entirely sure if those dependencies would work out. But if you still get the same error I would suggest tweaking the version of tb-nightly because I guess that's the package that breaks.

@lineojcd It's been a while since you asked but in case if you're still working on this feel free to give it a shot. Sorry about the late reply.

@ericchen321 @lineojcd I got mine to work by downgrading my absl_py library to I think 0.80 or something like that. And I uninstalled pytorch and installed a version of pytorch that was compiled to run in CUDA11.3 run time, although I suspect other versions of CUDA would work too: pip install torch --extra-index-url https://download.pytorch.org/whl/cu113

[ericchen321]

Thanks for suggesting this. I've updated instructions to suggest users install CUDA-compiled torch if they have an NVIDIA card.
