On a positive note, multiple GPUs are working.
I have updated the code as follows to resolve the error:
Code block 1
import os
import time
#!pip install -q -U tensorflow-gpu
import tensorflow as tf
from tensorflow.compat.v1 import ConfigProto
from tensorflow.compat.v1 import InteractiveSession
config = ConfigProto()
config.gpu_options.allow_growth = True
config.log_device_placement = True
sess = tf.Session(config=config)
os.environ['TF_FORCE_GPU_ALLOW_GROWTH'] = 'true'
import numpy as np
and all syntax with tf.contrib.distribute.MirroredStrategy(num_gpus=NUM_GPUS) are replaced with tf.contrib.distribute.MirroredStrategy(num_gpus=NUM_GPUS,cross_device_ops=tf.distribute.HierarchicalCopyAllReduce())
I have also updated the batch size to see if this resolves it, however none of the updates work.
