Can't build openpilot (op build) on Ubuntu 24.04 ARM64

Hey everyone,

I've run into a snag while trying to build openpilot on Ubuntu 24.04 ARM64, and I wanted to share the issue and see if anyone has encountered something similar or has any insights. Basically, the op build command is failing, and it seems to be related to a dependency issue with the dearpygui package. Let's dive into the details so you guys can help me figure out this problem.

Describe the bug

I'm unable to build openpilot on Ubuntu 24.04 ARM64 (specifically, in an Ubuntu VM running on Apple Silicon macOS). When I run op build, I encounter the following error:

success: Upgraded uv from v0.8.13 to v0.9.8! https://github.com/astral-sh/uv/releases/tag/0.9.8
installing python packages...
error: Distribution `dearpygui==2.1.0 @ registry+https://pypi.org/simple` can't be installed because it doesn't have a source distribution or wheel for the current platform

hint: You're on Linux (`manylinux_2_39_aarch64`), but `dearpygui` (v2.1.0) only has wheels for the following platforms: `manylinux1_x86_64`, `macosx_10_6_x86_64`, `macosx_13_0_arm64`, `win_amd64`; consider adding "sys_platform == 'linux' and platform_machine == 'aarch64'" to `tool.uv.required-environments` to ensure uv resolves to a version with compatible wheels
 ↳ [✗] Dependencies installation failed!

This error suggests that the dearpygui package doesn't have pre-built wheels available for the aarch64 architecture on Linux. It seems like the installation process is trying to find a pre-compiled version of the package, but it can only find versions for x86_64, macosx, and win_amd64. This is a common issue when dealing with platform-specific Python packages. The error message also provides a hint about modifying the tool.uv.required-environments configuration to potentially resolve this, but I haven't had luck with that yet. Essentially, the package manager uv is unable to find a compatible version of dearpygui for the ARM64 architecture, causing the build process to fail. This incompatibility arises because dearpygui's pre-built wheels don't include support for the specific architecture and operating system combination I'm using. The error highlights the challenges of cross-platform compatibility and the importance of ensuring that all dependencies have appropriate builds for the target environment. This issue prevents me from proceeding with the openpilot build, hindering development and testing on the ARM64 platform. Resolving this dependency problem is crucial for enabling openpilot functionality on devices with ARM64 architecture, expanding its compatibility and potential user base. This will likely involve either finding a compatible version of the dearpygui package, building it from source, or exploring alternative solutions to meet the dependency requirements of openpilot on ARM64 systems. I am looking forward to suggestions from the community.

Possible Solutions and Troubleshooting Steps for Building Openpilot on Ubuntu 24.04 ARM64

Okay, so let's brainstorm some potential solutions and troubleshooting steps to tackle this build failure. Since the core issue seems to be the lack of a pre-built dearpygui wheel for the aarch64 architecture, we need to explore ways to either get a compatible wheel or build the package from source. Here are some ideas:

  1. Building from Source: The most direct approach is to try building dearpygui from source. This would involve downloading the source code and compiling it specifically for the ARM64 architecture. Here's a general outline of how you might do this:

    • Install build dependencies: You'll need to make sure you have the necessary tools to compile Python packages. This usually includes python3-dev, build-essential, and cmake.

      sudo apt update
sudo apt install python3-dev build-essential cmake

    • Download the source code: You can usually find the source code on PyPI or the project's GitHub repository. Download the version that matches the one causing the issue (in this case, 2.1.0).

    • Build and install: Navigate to the directory containing the source code and run the following commands:

      python3 -m pip install --no-binary :all: dearpygui==2.1.0

      The --no-binary :all: flag forces pip to build from source. Be patient, as this can take a while.

      Important: Building from source can sometimes be tricky, especially if the package has complex dependencies or requires specific system libraries. Read the dearpygui documentation for specific build instructions.

  2. Using a Conda Environment: Conda can sometimes resolve dependency issues more effectively than pip, especially when dealing with platform-specific packages. Create a Conda environment and try installing openpilot within it:

    • Install Conda: If you don't have Conda, install Miniconda (a minimal version of Anaconda).

    • Create an environment:

      conda create -n openpilot python=3.8  # Or whichever Python version openpilot requires
conda activate openpilot

    • Try building openpilot: After activating the environment, try running op build again. Conda might be able to find or build a compatible version of dearpygui.

  3. Checking for Alternative Wheels: Sometimes, there are unofficial or experimental wheels available for different architectures. You can try searching for dearpygui wheels specifically for aarch64 on Linux. However, be cautious when using unofficial packages, and make sure they come from a trusted source.

  4. Modifying tool.uv.required-environments: The error message suggests modifying this configuration. This file likely controls how uv resolves dependencies. You could try adding a condition that specifies a different version of dearpygui or a different installation method for aarch64 Linux. However, without more information about this file and how uv works, this approach might require some experimentation.

  5. Docker Container: Using a Docker container with a pre-configured environment can often bypass dependency issues. Check if there's a Dockerfile available for building openpilot on ARM64 or if you can create one yourself. This would involve setting up an Ubuntu 24.04 ARM64 base image and installing all the necessary dependencies within the container.

  6. Virtual Environment with Specific Python Version: Ensure you are using a Python version that is compatible with dearpygui. Sometimes, newer Python versions might have compatibility issues with older packages. Create a virtual environment with a specific Python version (e.g., Python 3.8 or 3.9) and try installing the dependencies again.

    python3 -m venv .venv
source .venv/bin/activate
pip install --upgrade pip
pip install -r requirements.txt # Or however you install openpilot dependencies

  7. System Package Dependencies: Make sure that all the system-level dependencies required by dearpygui are installed. This might include specific graphics libraries or other system packages that are not automatically installed by pip or conda. Consult the dearpygui documentation for a list of system dependencies.

  8. Contacting the openpilot Community: Reach out to the openpilot community for help. They might have encountered this issue before and have a solution. Provide them with detailed information about your setup (OS version, openpilot version, error messages) so they can assist you effectively. Check the openpilot GitHub issues, forums, or Discord channels for relevant discussions.

  9. Reporting the Issue to dearpygui: If you've exhausted all other options, consider reporting the issue to the dearpygui developers. They might be able to provide a fix or suggest a workaround.

Important Considerations:

  • Compatibility: Always check the compatibility of the dearpygui version with the specific version of openpilot you're trying to build.
  • Documentation: Refer to the official documentation for both openpilot and dearpygui for detailed installation instructions and troubleshooting tips.
  • Logs: Examine the build logs carefully for any additional error messages or warnings that might provide clues about the cause of the failure.

I hope these suggestions help! Let me know if you've tried any of these steps or if you have any other ideas. I am very happy to work together on this problem.

Updating pip and setuptools

It's a good practice to ensure that your pip and setuptools are up to date. Outdated versions can sometimes cause unexpected issues during package installation. Here’s how you can update them:

python3 -m pip install --upgrade pip setuptools

This command updates pip and setuptools to their latest versions, which can resolve compatibility issues with newer packages or build tools. Keeping these tools updated ensures you're using the most recent features and bug fixes, which can improve the reliability of package installations.

Creating a Virtual Environment

Using a virtual environment is crucial for managing dependencies in Python projects. It creates an isolated environment for your project, preventing conflicts with other projects or system-wide packages. Here’s how to create and activate a virtual environment:

python3 -m venv .venv
source .venv/bin/activate

These commands create a new virtual environment in the .venv directory and activate it. Once activated, any packages you install will be contained within this environment, keeping your project's dependencies separate and organized. This practice ensures that your project's dependencies don't interfere with other projects on your system.

Checking System Dependencies

Sometimes, Python packages rely on system-level libraries. Missing or outdated system dependencies can cause installation failures. Make sure that all the necessary system dependencies are installed on your Ubuntu system. You can check the package's documentation or online resources to identify the required system dependencies and install them using apt:

sudo apt update
sudo apt install <system-dependency>

Replace <system-dependency> with the actual name of the system library you need to install. Ensuring that all system dependencies are in place can resolve installation issues caused by missing or outdated libraries.

Conclusion

Building openpilot on Ubuntu 24.04 ARM64 can be challenging due to dependency issues, particularly with packages like dearpygui. By following the troubleshooting steps outlined above, such as building from source, using Conda environments, and ensuring system dependencies are met, you can increase your chances of successfully building openpilot on your system. Additionally, keeping your tools like pip and setuptools updated and utilizing virtual environments can help prevent dependency conflicts and maintain a clean development environment. Remember to consult the official documentation for openpilot and its dependencies for specific instructions and compatibility information. Good luck, and happy building!
