ERROR: Failed to build 'flatdict' when getting requirements to build wheel

[EverNorif]

Could you reinstall according to this detailed installation guide and see at which step the issue occurs?

[dcastelberg]

Not the issue author, but I ran into the same problem. To reproduce, follow the installation guide as found on https://lightwheelai.github.io/leisaac/docs/getting_started/installation/#install-from-source

When running ./isaaclab.sh --install, the wheel for flatdict==4.0.1 fails to build with the following error message:

ERROR: Failed to build 'flatdict' when getting requirements to build wheel

The flatdict version is pinned to 4.0.1 in dependencies/IsaacLab/source/isaaclab/setup.py, and setting it to 4.0.0 resolves the issue.

So this is an issue in IsaacLab (or, more precisely, in flatdict) and there exists a workaround (isaac-sim/IsaacLab#4577).

IsaacLab has implemented this change a while ago (isaac-sim/IsaacLab@73930be), so unless there are compatibility issues between leisaac and the current IsaacLab version, updating the IsaacLab dependency provided by this repository should resolve the issue.

[EverNorif]

@dcastelberg Thank you for your feedback.

[EverNorif]

leisaac does not depend on the latest version of Isaac Lab, so the corresponding commit is not included. To resolve the installation issue with Isaac Lab, please temporarily pin the version of flatdict.

[Priyabhunia]

how to update the version , I am following the first package installation setup and seems like there is no way to update the version in issac lab . can someone clear something out fast what is the steps

[EverNorif]

@Priyabhunia You can refer to the script below.

cd dependencies/IsaacLab
sed -i 's/flatdict==4.0.1/flatdict==4.0.0/' source/isaaclab/setup.py
bash isaaclab.sh --install
git checkout -- source/isaaclab/setup.py
