Getting non-deterministic results running EfficientnetB0/Efficinetnet-lite0 models on GPU (using tensorflow-gpu 2.2)

The following random seeds were set

SEED = 1
random.seed(SEED)
np.random.seed(SEED)
tf.random.set_seed(SEED)

The following Environmental Variables were set TRUE

os.environ['TF_CUDNN_DETERMINISTIC'] = TRUE
os.environ['TF_DETERMINISTIC_OPS'] = TRUE

What could possibly be the source of the issue?
