TensorFlow on the cluster
Introduction
This page is intended to help you access or setup TensorFlow on the FASRC Cluster.
GPU support
At time of writing the latest release stable of TensorFlow is 1.12. Tensorflow 1.12 requires the runtime cuda 9.0 and the cudnn version >= 7.2. Also, at the time of writing the latest version available as wheel with pip is for python3.6. Support for Python 3.7 was not yet added. The current CUDA runtime for GPU-enabled nodes on the cluster is 10.0. So TF 1.12 should work on all GPU nodes. Please refer to our documentation on how to submit run GPU jobs on the cluster. The two recommended solutions for setting up TensorFlow are to install the latest version in a python conda environment inside your user folder, or run Tensorflow as singularity container.
Install in a conda environment
At time of writing the latest release of TensorFlow is 1.12 , and it requires the runtime cuda 9.0 and the cudnn version 7.2 or newer . You can install your own TF following these simple steps. #1. load Anaconda, cuda and cudnn
>$ module load Anaconda3/5.0.1-fasrc01
>$ module load cuda/9.0-fasrc02 cudnn/7.4.1.5_cuda9.0-fasrc01 #2. create a new environment with the latest python3 and some dependencies needed by TensorFlow >$ conda create -n tf1.12_cuda9 python=3.6 numpy six wheel #3. activate the conda environment>$ source activate tf1.12_cuda9 #4. use pip to install tensorflow(tf1.12_cuda9)>$ pip install --upgrade tensorflow-gpu==1.12 Please note that while you can run the installation on the login nodes, you will not be able to use the software on the login nodes as there is no GPU on the login servers. Also, please remember that when you want to use your tensorflow installation, you need to execute step 1. ( load the modules ) and 3. ( activate your environment ).
Running Tensorflow as a singularity container
Alternatively, you can run TensorFlow as a singularity container. >$ singularity exec --nv docker://tensorflow/tensorflow:latest-gpu python myCNN.py
CPU version
Install in a conda environment
At time of writing the latest release of TensorFlow is 1.10.0, You can install your own version following these simple steps. #1. load Anaconda, cuda and cudnn
>$ module load Anaconda3/5.0.1-fasrc01 #2. create a new environment with the latest python3 and some dependencies needed by TensorFlow >$ conda create -n tf1.12 python=3.6 numpy six wheel #3. activate the conda environment>$ source activate tf1.12 #4. use pip to install tensorflow(tf1.10)>$ pip install --upgrade tensorflow==1.12
If you would like to work with the CPU version of Tensorflow, you should also consider trying to use the version provided by Intel . Please note that this version is only working on Intel hardware, so you will be able to run on partitions “shared”, “test” or any other Intel based priority partition your lab might have access to. Please note that the code will not run in the “general” partition or on the login nodes, as those servers feature AMD processors. At time of writing the latest version of TensorFlow released as wheel by Intel is 1.9.0. However versions more recent than 1.6 seem to have conflicts with versions of the c/c++ library we currently have installed by default on the cluster. You can setup version 1.6 in a conda environment, following the steps below, or you can use versions more recent than that as a singularity container.
Install in a conda environment
#1. load Anaconda
>$ module load Anaconda3/5.0.1-fasrc01 #2. create a new environment with the latest python3 and some dependencies needed by TensorFlow from the Intel channel>$conda create -n tf1.6_intel -c intel python=3.6 pip numpy #3. activate the conda environment>$ source activate tf1.6_intel #4. use pip to install tensorflow(tf1.6_intel)>$pip install --no-cache-dir https://anaconda.org/intel/tensorflow/1.6.0/download/tensorflow-1.6.0-cp36-cp36m-linux_x86_64.whl
Running Tensorflow as a singularity container
Alternatively, you can run TensorFlow as a singularity container. >$ singularity exec docker://tensorflow/tensorflow:latest python myCNN.py Or, if you want to use the Intel version >$ singularity exec docker://intelaipg/intel-optimized-tensorflow:latest-py3 python myCNN.py … Discussion on optimization considerations coming soon…
