ModuleNotFoundError: No module named 'isaaclab' via Binary Installation

[JLCucumber]

Hi all,

I followed this link trying to install my Isaac Lab. I'm sure I followed every step listed in the document, but when I try to test Isaac Lab in my conda environment. I got No module named 'isaaclab'. I have tried to search for this issue but none of them are exactly the same. #703 is the most similar one to my case, the only difference is that I only run ./isaac_lab.sh --install outside of the conda env:

$ git clone [email protected]:isaac-sim/IsaacLab.git
$ cd IsaacLab
$ ln -s path_to_isaac_sim _isaac_sim
$ ./isaaclab.sh --conda
[INFO] Using default conda environment name: env_isaaclab
[INFO] Creating conda environment named 'env_isaaclab'...
...
# $ ./isaaclab.sh --install <<< this is how I did the installation
$ conda activate env_isaaclab
$ ./isaaclab.sh --install  <<< this is where #703 did the installation

The exact command I used is here

# Option 1: Using the isaaclab.sh executable
# note: this works for both the bundled python and the virtual environment
./isaaclab.sh -p scripts/tutorials/00_sim/create_empty.py

# Option 2: Using python in your virtual environment
python scripts/tutorials/00_sim/create_empty.py

My system:

• Ubuntu 22.04
• RTX 4080
• Isaac Sim 4.5 & Isaac Lab 2.1.0

Any help or advice means a lot to me. Thanks!

Immediately solved after I re-run the ./isaaclab.sh --install inside the conda env. But will that be causing any problem if I did the ./isaaclab.sh --install twice (inside conda env and outside of it)?

running ./isaaclab.sh --install outside the conda env will not install the isaaclab modules to the conda python. it will need to be run inside the conda env.
