UserWarning: Converting sparse IndexedSlices to a dense Tensor of unknown shape. #11

Closed fengjunhui closed 6 years ago

fengjunhui commented 6 years ago

There is a UserWarning problem when I run python ./chem_tensorflow_sparse.py. This is the detail : UserWarning: Converting sparse IndexedSlices to a dense Tensor of unknown shape. This may consume a large amount of memory. "Converting sparse IndexedSlices to a dense Tensor of unknown shape. "

This is spurious warning, caused by the application of a tf.nn.embedding_lookup operation on a non-Variable object (namely, node_states_per_layer[-1]). While this /can/ lead to massive performance degradation, it does not do so in this case, and so the warning can be safely ignored.
