For an operation to have float operation statistics:
-* It must have `RegisterStatistics('flops')` defined in TensorFlow. tfprof
-use the definition to calculate float operations. Contributes are welcome.
-
-* It must have known "shape" information for RegisterStatistics('flops')
-to calculate the statistics. It is suggested to pass in `-run_meta_path` if
-shape is only known during runtime. tfprof can fill in the missing shape with
-the runtime shape information from RunMetadata.
-Hence, it is suggested to use `-account_displayed_op_only`
-option so that you know the statistics are only for the operations printed out.
-
-* If no RunMetadata provided, tfprof count float_ops of each graph node once,
-even if it is defined in tf.while_loop. This is because tfprof doesn't know
-how many times are run statically. If RunMetadata provided, tfprof calculate
-float_ops as float_ops * run_count.

# To profile float opertions in commandline, you need to pass --graph_path
