Running into installation issues with Deeplabcut on Compute Canada can feel frustrating—especially when you’re eager to dive into your research. Deeplabcut 2.3.11 is widely used for video analysis in fields like neuroscience, biology, and biomechanics. Ensuring a smooth setup on HPC systems like Compute Canada is crucial for productive analysis and streamlined workflows.
Setting up Deeplabcut 2.3.11 on Compute Canada’s machines
Compute Canada clusters typically offer powerful hardware configurations, making them ideal for running computationally-intensive software like Deeplabcut. Before installation, it’s helpful to be familiar with the system specs you’re dealing with. Usually, Compute Canada runs Linux-based operating systems with pre-installed software modules.
When preparing your conda environment for Deeplabcut, attention to detail matters. Ideally, Deeplabcut 2.3.11 works seamlessly with Python versions 3.8-3.9, but issues arise with Python 3.10.16 installed via Conda. You’ll also need to pay close attention to your pip and conda versions—older versions might lead to compatibility issues during installation.
Error encountered during installation
If you’ve tried installing Deeplabcut via pip in your existing conda environment, you’ve probably spotted an error similar to this:
ImportError: libGL.so.1: cannot open shared object file: No such file or directory
This problem usually occurs due to OpenCV, a dependency Deeplabcut heavily relies on. The Compute Canada cluster environment doesn’t always include necessary graphical libraries by default, prompting missing shared library errors.
Many users initially try loading system modules to fix this by running commands such as:
module load opencv
Unfortunately, loading the module alone might not always solve the issue. This error often persists due to deeper compatibility issues between packages or incorrect paths set in conda.
Why is the Deeplabcut installation failing?
Two main culprits usually cause Deeplabcut installation headaches on Compute Canada clusters:
- Compatibility issues with Python version: Python versions above 3.9 can trigger compatibility problems with key Deeplabcut dependencies, notably TensorFlow and OpenCV. Version 3.10.16—the current default Conda Python—often leads to conflicts.
- Dependency conflicts: Packages installed by Conda might conflict with pip-installed packages, causing unexpected errors during runtime or installation.
Given these potential pitfalls, troubleshooting can be challenging but is usually straightforward if you know what to look for.
Quick troubleshooting steps to fix your Deeplabcut installation
To ensure Deeplabcut installs smoothly on Compute Canada, you should first verify your system meets the software’s specific requirements. Here are practical steps that help tackle the productively:
- Check Deeplabcut’s requirements: Confirm your conda environment aligns with official Deeplabcut requirements, including Python version and other packages like TensorFlow and OpenCV.
- Update Conda and pip first: Older package managers often cause subtle but costly errors.
conda update conda pip install --upgrade pip - Resolve libGL.so.1 error explicitly: To fix issues with OpenCV, installing the missing graphical package libraries directly can help:
conda install -c conda-forge opencv conda install -c conda-forge libglvnd-glxIf Conda packages don’t fix the error, consider installing needed Linux packages directly using:
module load StdEnv/2020 # basic standard Compute Canada environment module load gcc/9.3.0 opencv/4.5.2
These steps often resolve most basic installation issues encountered with Deeplabcut.
Alternative methods: Creating clean environments
If all troubleshooting attempts fail, it’s always safer and quicker to build a clean conda environment from scratch. Fresh environments ensure there aren’t leftover dependencies lurking around causing trouble.
Create a clean conda environment explicitly specifying Python version compatibility like Python 3.8 or 3.9:
conda create -n dlc_env python=3.8
conda activate dlc_env
pip install deeplabcut==2.3.11
Virtual environments (venv) may also offer easier package management. However, Conda usually handles package conflicts more robustly, especially for complex software stacks involving scientific computing packages.

Testing your new Deeplabcut installation
After installation, the first thing you’ll want is to verify everything runs smoothly. Deeplabcut comes with built-in commands helpful in quick diagnostics.
Run this simple command to ensure Deeplabcut was properly installed:
python -c "import deeplabcut; deeplabcut.__version__"
If everything runs fine without error messages, you’re set. You might also test some basic Deeplabcut functionalities on a provided sample dataset or your own quick project to guarantee functionality before diving deeper.
Fine-tuning Deeplabcut for your workflow
Deeplabcut isn’t just a vanilla model—you can fine-tune and customize it significantly for your specific task limitations and objectives. Adjusting hyperparameters, data augmentation methods, or even customizing neural network architectures allows you to maximize performance for your research questions.
Combining Deeplabcut with additional analysis tools like NumPy, OpenCV, or Pandas might also streamline your overall workflow. Integrating your Deeplabcut data into visualization platforms or downstream analysis tools can significantly enhance your research outcomes.
In short, taking the extra time upfront to properly configure, optimize, and integrate Deeplabcut saves tremendous effort later, ensuring your research runs efficiently and accurately.
Setting up Deeplabcut on Compute Canada isn’t always smooth sailing, but once resolved, it provides an excellent resource to support sophisticated, rigorous analyses.
