Request for a requirements.txt file

[itazap]

Bug description

This library depends on specific versions of certain packages, and it would really help streamline the installation process by contributing a requirements.txt file to outline the necessary dependent packages. Thanks!

Expected behavior

users can then run pip install -r requirements.txt

Code

this file can simply be created with:
pip freeze > requirements.txt

Thank you for raising this. While requirements.txt files are still a thing, in this project we rather specify dependencies in pyproject.toml:

upkie/pyproject.toml

Lines 30 to 37 in 96d2fde

	dependencies = [
	"gymnasium >= 0.29.1",
	"loop-rate-limiters >= 1.0.0",
	"msgpack >= 1.0.2",
	"numpy >= 1.24.3",
	"scipy >= 1.10.0",
	"upkie_description >= 2.1.0",
	]

If your use case is to install the project from source, you can run from the repository:

pip install .

This will automatically fetch all dependencies from PyPI with proper versions, and install any local changes you may have from source.

Thank you @stephane-caron ! I was having conflicts with the dependencies for ppo_balancer, but a fresh restart helped. On that note, does https://github.com/upkie/ppo_balancer require dependencies like xcode? Unable to get the make train to work without errors. Thanks again for your response!

Update: unable to get passed this error:

ERROR: /private/var/tmp/_bazel_itazaporozhets/498dbf992c37892e7013f5ba2c923d0f/external/local_config_cc/BUILD:48:19: in cc_toolchain_suite rule @local_config_cc//:toolchain: cc_toolchain_suite '@local_config_cc//:toolchain' does not contain a toolchain for cpu 'darwin_x86_74'

was wondering if there is a cpp-related or intel-related dependency ? I was able to run make test_policy but not make train. Thanks.

Hmm the string "darwin_x86_74" should be "darwin_x86_64" (standing for 64 bits). I don't find the incorrect string in the repositories, so it is possible you have some local changes. You can search for that string in your local files and correct it if found, or maybe start afresh from a clean git clone of the repositories?

For info, the string "darwin_x86_64" appears in the .bazelrc file of the upkie repository.

Acutally yes the error was with "64", that's my mistake, I clipped the error when copy-pasting and manually retyping the error
