Error when training with pretrained model

[At-Walid]

Hello,

I followed your tutorial but I'm getting the following error:

`ERROR:tensorflow:==================================
Object was never used (type <class 'tensorflow.python.framework.ops.Tensor'>):
<tf.Tensor 'init_ops/report_uninitialized_variables/boolean_mask/GatherV2:0' shape=(?,) dtype=string>
If you want to mark it as used call its "mark_used()" method.

Looks like the SyncReplicaOptimizer is no longer supported by tensorflow. DistributedStrategy can be used to replace the functionalities. I found that out here and the solve is described in further detail here.

Thank you for your response. I looked at the code, and I can't find where SyncReplicaOptimizer is used
