Prints Given Tensors Every N Local Steps, Every N Seconds, or at End

The tensors will be printed to the log, with INFO severity.

hook_logging_tensor(tensors, every_n_iter = NULL, every_n_secs = NULL,
  formatter = NULL, at_end = FALSE)

Arguments

tensors	A list that maps string-valued tags to tensors/tensor names.
every_n_iter	An integer value, indicating the values of `tensors` will be printed once every N local steps taken on the current worker.
every_n_secs	An integer or float value, indicating the values of `tensors` will be printed once every N seconds. Exactly one of `every_n_iter` and `every_n_secs` should be provided.
formatter	A function that takes `list(tag = tensor)` and returns a string. If `NULL` uses default printing all tensors.
at_end	A boolean value specifying whether to print the values of `tensors` at the end of the run.

Note that if at_end is TRUE, tensors should not include any tensor whose evaluation produces a side effect such as consuming additional inputs.
