Running Tensorflow with Conda

Beware that these builds use CUDA and will not work on login nodes, which does not have CUDA installed as there are no GPUs.

Tensorflow (master build)

Given A100 and CUDA 11 are very new, we have a build of the master branch of Tensorflow which includes better performance and support for these architectures.

Users can find the latest builds via the module avail conda command, which will list available builds such as conda/2021-06-26 which is a module that was built on 2021-06-26. Use module show conda/2021-06-26 or module help conda/2021-06-26 to get high level info on which versions of the key packages and libraries that this particular module contains.

This version can be used by:

module load conda/2021-06-26  # loads conda into your environment, sets up appropriate CUDA libraries
conda activate # activates conda with python
This will setup a conda environment with the "from scratch" build of TensorFlow.

This package will also include builds of PyTorch and Horovod tagged releases.

Installing Packages

Using pip install --user

With the conda environment setup, one can install common Python modules using pip install --users <module-name> which will install packages in $HOME/.local/lib/pythonX.Y/site-packages.

Using Conda Environments

If you need more flexibility, you can clone the conda environment into a custom path, which would then allow for root-like installations via conda install <module> or pip install <module>.

  1. Setup the conda environment you want to use as instructed above.

  2. Create/edit your $HOME/.condarc file to include this these lines, replacing <project-name> with your project name. By default, Conda will your $HOME/.conda/* area for caching files.

Note: Since home directories are limited to 100GB, this fills up quickly. This addition tells Conda to use your project space for cache storage instead.

   - /lus/theta-fs0/projects/<project-name>/conda/pkgs 
   - /lus/theta-fs0/projects/<project-name>/conda/envs
3. Clone the environment into a local path to which you have write access.
conda create --clone $CONDA_PREFIX -p <path/to/env>
4. Activate that environment.
conda activate <path/to/env>

One should then be able to install modules natively.
