See the guide: TensorFlow Debugger > Functions for adding debug watches
Add debug tensor watches, blacklisting nodes and op types.
This is similar to watch_graph()
, but the node names and op types are blacklisted, instead of whitelisted.
N.B.: 1. Under certain circumstances, the Tensor
may not get actually watched (e.g., if the node of the Tensor
is constant-folded during runtime). 2. For debugging purposes, the parallel_iteration
attribute of all tf.while_loop
s in the graph are set to 1 to prevent any node from being executed multiple times concurrently. This change does not affect subsequent non-debugged runs of the same tf.while_loop
s.
Args:
-
run_options
: An instance ofconfig_pb2.RunOptions
to be modified. -
graph
: An instance ofops.Graph
. -
debug_ops
: (str
orlist
ofstr
) name(s) of the debug op(s) to use. See the documentation ofwatch_graph
for more details. -
debug_urls
: URL(s) to send debug values to, e.g.,file:///tmp/tfdbg_dump_1
,grpc://localhost:12345
. -
node_name_regex_blacklist
: Regular-expression blacklist for node_name. This should be a string, e.g.,"(weight_[0-9]+|bias_.*)"
. -
op_type_regex_blacklist
: Regular-expression blacklist for the op type of nodes, e.g.,"(Variable|Add)"
. If both node_name_regex_blacklist and op_type_regex_blacklist are set, the two filtering operations will occur in a logicalOR
relation. In other words, a node will be excluded if it hits either of the two blacklists; a node will be included if and only if it hits neither of the blacklists. -
tensor_dtype_regex_blacklist
: Regular-experssion blacklist for Tensor data type, e.g.,"^int.*"
. This blacklist operates in logicalOR
relations to the two whitelists above. -
tolerate_debug_op_creation_failures
: (bool
) whether debug op creation failures (e.g., due to dtype incompatibility) are to be tolerated by not throwing exceptions. -
global_step
: (int
) Optional global_step count for this debug tensor watch.
