Package unavailable MacOS ARM64

[momoai96]

Hey guys,

I followed your installation guide and set up a conda environment.
I'm currently working on macOS Big Sur 11.5.1 Arm 64 with Apple Silicon.

After setting up channels, I tried : "conda install ros-noetic-desktop", but received only an error:

"PackagesNotFoundError: The following packages are not available from current channels:

• ros-noetic-desktop"

What am I doing wrong?

[Tobias-Fischer]

Hi @momoai96, many thanks for your interest in RoboStack! Unfortunately ros-noetic-desktop is not yet available for Apple Silicon - please refer to this table for available packages. You can still run the "standard" osx64 packages via Rosetta though, including ros-noetic-desktop.

We are currently stuck with some cross-compilation issues - if you are interested, have a look here. @wolfv - do you have any suggestions how to get around the issue? Do we have an osx-arm64 machine for conda-forge that we could use to build packages natively?

[momoai96]

Thanks for your fast answering!
What are the steps to install Ros noetic with Rosetta?

[Tobias-Fischer]

Hi, please refer to this issue to create a conda environment that uses Intel packages. Let us know if it works :)

[momoai96]

Hey Guys,

sorry for my late answer, got some work to do with my master thesis.
I followed your installation steps and first it seemed to work.

After opening a terminal, activating my env and call RVIZ, I received :
" Could not contact ROS master at [http://localhost:11311], retrying..."

Any tips?

[momoai96]

Forget everything! :)
After calling Roscore in a different terminal it worked well!
Thank you Guys! You did amazing stuff!

[waasnipun]

@momoai96 Did it work? I am still getting the same error even after switching to intel. Any help?

Error -
PackagesNotFoundError: The following packages are not available from current channels:

• ros-noetic-desktop

[Tobias-Fischer]

Please also provide the command/steps that you used. It's very hard to debug the issue with just an error message.

[momoai96]

@waasnipun

yes, it worked really well!
No problems!

Just create a conda env based on rosetta to emulate osx-64.
Afterwards you can install ros noetic.
Run Roscore in a new terminal to work as usual!

[waasnipun]

First I ran this to emulate osx-64

CONDA_SUBDIR=osx-64 conda create -n robostackenv python=3.8
conda env config vars set CONDA_SUBDIR=osx-64
conda deactivate robostackenv
conda activate robostackenv
echo "CONDA_SUBDIR: $CONDA_SUBDIR"

Then ran

conda config --env --add channels conda-forge
conda config --env --add channels robostack
conda config --env --set channel_priority strict

conda install ros-noetic-desktop

This was the error

Collecting package metadata (current_repodata.json): done
Solving environment: failed with initial frozen solve. Retrying with flexible solve.

Current channels:

To search for alternate channels that may provide the conda package you're
looking for, navigate to

and use the search bar at the top of the page.

[Tobias-Fischer]

I think you need to call conda env config vars set CONDA_SUBDIR=osx-64 after conda activate robostackenv. At the moment, it is still looking for packages in the osx-arm64 subdirectory.

In worst case, you can prepend CONDA_SUBDIR=osx-64 to call conda/mamba calls (we really suggest using mamba instead of conda).

[waasnipun]

CONDA_SUBDIR=osx-64 mamba install ros-noetic-desktop worked. Thanks

[Tobias-Fischer]

Just an update: on ROS2 Galactic, we now have ros-galactic-desktop natively for the M1. If there is interest to get the same working on Noetic, I could point a volunteer to some relevant commits & patches to get the same working for Noetic.

[Tobias-Fischer]

We now have a significant chuck of packages. Note that RoboStack/ros-galactic#73 is still an issue.

Hi there.

I'm trying to install ROS Noetic on my mac M1 (12.2). So far no success, as it seems to always miss a package during the installation of the ros-noetic-desktop package.

• with python=3.9:

Encountered problems while solving:
  - package ros-noetic-desktop-1.5.0-py39heb88ffd_15 requires ros-noetic-viz, but none of the providers can be installed

• with python=3.8:

Encountered problems while solving:
  - package ros-noetic-desktop-1.5.0-py38hb43b470_13 requires ros-noetic-joint-state-publisher-gui, but none of the providers can be installed

The environment is correctly configured to use Rosetta as per the link mentioned above.

Any idea on how to solve this? Thanks!

[Tobias-Fischer]

Could you please specify the exact commands you are running so it's easier to reproduce the issue?

[sylarevan]

Yes sure.
Here are the exact commands I used, from the very beginning:

• First, installation of mambaforge through brew (I'm using fish shell):

brew install mambaforge
conda init fish

• Next, the environment configuration:

CONDA_SUBDIR=osx-64 conda create -n robostack_rosetta python=3.8
conda activate robostack_rosetta
conda env config vars set CONDA_SUBDIR=osx-64
conda deactivate
conda activate robostack_rosetta

Here CONDA_SUBDIR is correctly defined when re-activating the environment (echo $CONDA_SUBDIR gives osx-64).

• Finally, RoboStack itself:

conda config --env --add channels robostack-experimental
conda config --env --add channels robostack
conda config --env --set channel_priority strict
mamba install ros-noetic-desktop

Here is what is present in my environment:

And the exact output of mamba install ros-noetic-desktop with an environment defined for python 3.8:

Encountered problems while solving:
  - package ros-noetic-desktop-1.5.0-py38hb43b470_13 requires ros-noetic-joint-state-publisher-gui, but none of the providers can be installed

So it seems that the packages with the correct architecture (osx-64) are used.

Depending on the python version, the error is not the same. With python 3.9, ros-noetic-viz seems not available this time.

[Tobias-Fischer]

Packages are now available natively on osx-arm64. Simply mamba install ros-noetic-desktop (without the CONDA_SUBDIR stuff) should work. Let me know.

[sylarevan]

Hi @Tobias-Fischer. I've switched to the osx-64 architecture since the package ros-noetic-viz was missing when installing ros-noetic-desktop yesterday with an arm64 architecture. I can confirm this not the case anymore today!
Anyway, thanks!
