 URL(s) for debug targets(s).
 Supported URL formats are:
   - file:///foo/tfdbg_dump: Writes out Event content to file
     /foo/tfdbg_dump.  Assumes all directories can be created if they don't
     already exist.
   - grpc://localhost:11011: Sends an RPC request to an EventListener
     service running at localhost:11011 with the event.
   - memcbk:///event_key: Routes tensors to clients using the
     callback registered with the DebugCallbackRegistry for event_key.
 Each debug op listed in debug_ops will publish its output tensor (debug
 signal) to all URLs in debug_urls.
 N.B. Session::Run() supports concurrent invocations of the same inputs
 (feed keys), outputs and target nodes. If such concurrent invocations
 are to be debugged, the callers of Session::Run() must use distinct
 debug_urls to make sure that the streamed or dumped events do not overlap
 among the invocations.

 Name of the node to watch.
 Use "*" for wildcard. But note: currently, regex is not supported in
 general.

 Output slot to watch.
 The semantics of output_slot == -1 is that all outputs of the node
 will be watched (i.e., a wildcard).
 Other negative values of output_slot are invalid and will lead to
 errors currently.
 

 Do not error out if debug op creation fails (e.g., due to dtype
 incompatibility). Instead, just log the failure.
