How to submit a job that uses TensorFlow

With this tutorial you will be able to submit a job that uses TensorFlow to the batch cluster.

The following steps allow the user to execute a Python script that uses TensorFlow and other Python libraries.

Copy the project folder to the cluster

[user@fedora ~]$ scp -r -J user@fw03 /home/user/my_project/ user@cirrus01

Access the cluster

[mcastro@fedora ~]$ ssh mcastro@cirrus01

Clone the reference repository

[user@cirrus01]$ git clone https://gitlab.com/lip-computing/computing/tf_run_job.git

Submit the job with the Python script inside project folder. In this example, the datasets are in my_datasets subfolder.

[user@cirrus01]$ cd my_project 
[user@cirrus01 my_project]$ sbatch ~/tf_run_job/run_job --input my_python_script.py --file my_datasets/dataset1.csv my_datasets/dataset2.csv

Once the job is completed the console log with the program messages will be written to a folder in the user's home directory.

[user@cirrus01 my_project]$ cat slurm-124811.out
