Hi, I try to use transforms3d python library in ROS2 Foxy (https://matthew-brett.github.io/trans...) for system test.

I put the dependency into package.xml:

<test_depend>python-transforms3d-pip</test_depend>

and included it into python written system test:

from transforms3d.quaternions import qmult, qinverse, quat2axangle

rosdep can install this dependency easily, but I faced an error if I try to use it with rosbuildfarm :(

10:10:21    - transforms3d
10:10:21  Traceback (most recent call last):
10:10:21    File "/usr/lib/python3/dist-packages/apt/cache.py", line 299, in __getitem__
10:10:21      rawpkg = self._cache[key]
10:10:21  KeyError: 'transforms3d'

It looks to me, that ros_buildfarm does not support installing libraries via pip?Is it ok? Or how to integrate this into ros buildfarm properly?

I'm going to close this as a duplicate of (at least) #q380279 and #q358667. There are a few more Q&As which discuss this topic.

For the specific dependency you mention, you may want to take a look at index.ros.org/p/tf_transformations, which I believe @David Lu released as he had a similar problem (in #q380279).

Thanks, you are right. I tried to find the answer in index.ros.org/p/tf_transformations, but I ended up using scipy.Rotation library instead, as there is no problem with this.

I was not able to find the answer quickly :/
