These packages and their dependencies form a nice but rather complicated example of Horovod allows for easy and flexible distributed parallelization of Keras/Tensorflow. Keras is an add-on to the framework that attempts to make it more user friendly. Tensorflow is a widely used deep learning framework. Parallel machine learning environment with Tensorflow, Keras and Horovod Note that in order to use GPU with Tensorflow, you need to request a GPU. In the OpenOnDemand Jupyter Lab app launch window, put the following in the Environment.Python -c "from import device_lib print(device_lib.list_local_devices())" This pip installed Tensorflow also includes Keras. Tensorflow builds in pip repositories, and the conda repositories don't have all the Note that we are using pip, not conda, since Google provides its Load the CUDA and CUDNN modules, and the newly installed Miniconda module (named a).Writing (December 2021), Tensorflow 2.5 requires CUDA 11.2 and CUDNN 8.1. Once the Miniconda3 and its module are installed, look at the Tensorflow installation requirements to note the CUDA and CUDNN versions that the latest Tensorflow requires. Since Tensorflow performs the best on the GPUs, we will be installing the GPU version. Jupyter Lab allows to run Jupyter notebooks, e.g. Examples Interactive machine learning environment with Tensorflow, Keras and Jupyter Lab cp a a), and in the new module file, specify the path where this particular miniconda is ForĮach independent miniconda installation, modify the miniconda module name (e.g. To use different miniconda installations instead of using virtual environments. The Lmod modules and Open Ondemand Jupyter notebooks. Furthermore, it is more complicated to wrap the VEs into Modules, their versions and dependencies, we occasionally see conflicts that are hard While the virtual environments provide convenient way to install different Python We recommend $HOME/software/pkg/miniconda3 for easy integration into user defined environment modules. It to the directory where you want to install it. Miniconda installation and usage Miniconda installationĭownload the Miniconda installer using the wget command and run the installer, pointing It can be either installed as a standalone or Intel Distribution for Python is provided by Intel with performance similar to Anaconda. For this reason it is not our top choice. GB as installed, which is a sizeable amount given our default 50 GB home directory Manager system, conda, and includes many commonly used Python modules. Intel MKL for fast and threaded numerical calculations. Selectivity makes it our choice for user space installation.Īnaconda is the most popular Python distribution. Packages need to be installed manually (described below). This makes the base installation rather small, at 0.3 GB. Miniconda is a minimal Anaconda distribution, which ships with base Python and the conda package manager. Is offered in a form of a Docker container, which can be imported and loaded in our HPC environment using Singularity. In those cases, we recommend to research if the particular stack Python library stack is difficult to install, mostly when there are conflicts betweenĭependent libraries. However, please, be aware that there are some corner cases when Anaconda/Miniconda Peformance improvements and are comparable or better to hand tuned Python builds.įor these reasons we are deprecating centrally maintained Python distributions and Space Python distributions, and specifically Anaconda/Miniconda, are actively incorporating On specific versions of modules which may be incompatible with others. Maintained Python distributions up to date. The Python ecosystem is growing rapidly and it has become difficult to keep centrally Why are we moving away from a central Python installation?
