Compiling TensorFlow v2.13.0 from source:
This is in conjunction with https://www.tensorflow.org/install/source but fills the gaps!

Install Bazel 5.3.0

Install the cuda toolkit v11.8 and get rid of any other cuda toolkits. Otherwise TF will find them and create chaos.
apt install cuda-toolkit-11-8

Install cudnn 8.7 (TF recommends 8.6 but 8.7 also works well):
apt-get install libcudnn8-dev=8.7.0.84-1+cuda11.8 libcudnn8=8.7.0.84-1+cuda11.8

In the main Application schedule the Worker as a one-off task and then re-schedule the task again:

    final OneTimeWorkRequest recWorkRequest =
            new OneTimeWorkRequest.Builder(RecWorker.class)
                    .build();
                    
                WorkManager
                        .getInstance(getApplicationContext())
                        .enqueueUniqueWork(RecWorker.TAG, ExistingWorkPolicy.REPLACE,recWorkRequest);
