Introduction

In the world of software development, compatibility issues can be a significant roadblock to progress. When working with complex tools like Whisperx and Ctranslate2, ensuring that they are compatible with your operating system and hardware can be a daunting task. In this article, we will delve into the challenges of getting Whisperx running on Ubuntu 24.04 using an NVIDIA T4 bare metal server, and explore the solutions that can help overcome these issues.

The Challenge: Whisperx and Ctranslate2 on Ubuntu 24.04

As a developer, you may have encountered the frustration of trying to get a specific software package to work on your system. In this case, the goal was to get Whisperx running on Ubuntu 24.04 using an NVIDIA T4 bare metal server. The server was not virtualized, which meant that the hardware was directly accessible to the operating system. However, despite the direct access, the installation of Whisperx using pipx resulted in errors.

Error Messages and Their Implications

The error messages that appeared during the installation process were indicative of a deeper issue. The message Could not load library libcudnn_ops_infer.so.8. Error: libcudnn_ops_infer.so.8: cannot open shared object file: No such file or directory suggested that there was a problem with the CUDA library. This library is a crucial component of the NVIDIA drivers, and its absence or incorrect version can cause a range of issues.

The Solution: Pinning Whisperx and Ctranslate2

After spending several days trying to resolve the issue, the solution was finally found. It involved pinning Whisperx and Ctranslate2 to specific versions that were known to work together. The versions that were used were:

  • Ctranslate2: 4.4.0
  • Whisperx: 3.3.2

These versions were installed using Python 3.12.3, and the specific packages that were used were:

  • ct2-fairseq-converter
  • ct2-marian-converter
  • ct2-openai-gpt2-converter
  • ct2-opennmt-py-converter
  • ct2-opennmt-tf-converter
  • ct2-opus-mt-converter
  • ct2-transformers-converter

Why Pinning is Important

Pinning software packages to specific versions can be a crucial step in ensuring compatibility. When different packages are installed, they may have dependencies on specific versions of other packages. If these dependencies are not met, the installation process can fail, or the software may not function as expected.

Benefits of Pinning

Pinning software packages has several benefits, including:

  • Improved compatibility: By pinning packages to specific versions, you can ensure that they are compatible with each other and with your operating system.
  • Reduced errors: Pinning packages can help reduce errors that occur during the installation process.
  • Increased reliability: Pinning packages can help increase the reliability of your software by ensuring that it is running with the correct versions of its dependencies.

Conclusion

In conclusion, getting Whisperx running on Ubuntu 24.04 using an NVIDIA T4 bare metal server required a combination of troubleshooting and pinning specific versions of the software packages. By pinning Whisperx and Ctranslate2 to versions 3.3.2 and 4.4.0, respectively, the installation process was successful, and the software was able to function as expected. This experience highlights the importance of pinning software packages to specific versions in order to ensure compatibility and reduce errors.

Recommendations

Based on this experience, the following recommendations can be made:

  • Always check the documentation: Before installing software packages, always check the documentation to ensure that you have the correct versions and dependencies.
  • Pin packages to specific versions: Pinning packages to specific versions can help ensure compatibility and reduce errors.
  • Test software thoroughly: Thoroughly test software after installation to ensure that it is functioning as expected.

Future Directions

In the future, it would be beneficial to explore other solutions for ensuring compatibility, such as using containerization or virtualization. Additionally, further research into the specific dependencies and requirements of Whisperx and Ctranslate2 could help identify potential issues and provide more effective solutions.
