. Consider either turning off auto-sharding or switching the auto_shard_policy to DATA to shard this dataset. You can do this by creating a new `tf.data.Options()` object then setting `options.experimental_distribute.auto_shard_policy = AutoShardPolicy.DATA` before applying the options object to the dataset via `dataset.with_options(options)`.

Hi,

Thanks for posting in Intel Communities.

Can you share the Intel DevCloud that you are using? Is it Intel DevCloud for oneAPI or FPGA or Edge?

Thank You.

Hi CLi37

we might need some time to further investigate this issue. please allow us some time to investigate it.

Thank you

Hi CLi37, 

Thank you for your patience and understanding, after further identifying the issue you face, it seems that you are trying to train some sample models on Intel® DevCloud for edge?

For your information, currently, the Intel® DevCloud for edge platform is not designed to train the model and its purpose is to simulate the OpenVINO inference engine on different hardware and generate the results for comparison. 

Regarding the issue you are facing, you can refer to this Stack Overflow discussion here

GeneratorDatasetOp:Dataset will not be optimized because the dataset does not implement the AsGraphD... 

Hope this information helps

Thank you
