* In some cases the RuntimeError object (tf_error in cli_shared.py) doesn't have
the op or its name available. Handle that situation properly.
* Previously, we used client graphs in the debugger CLI whenever it's available. This
has caused issues in which the device names
(e.g., "/device:GPU:0" vs "/job:localhost/replica:0/task:0/device:CPU:0").
This CL fixes that by favoring the runtime graph on the disk over the client graph.
The former has the actual device names.
Use the latter only if the former isn't available for some reason (e.g.,
writing graph to the disk failed.)
PiperOrigin-RevId: 200128582
Accompanying changes:
* In list_profile / lp output, let the time unit be consistent across all ops, so that the results are easier to read.
* Add the --time_unit option flag to list_profile / lp.
* Add start time to the lp output table; allow sorting by start time.

The bug was related to getting a string representation of feed_dict keys when the keys are str/unicode (in cli_shared.py: get_run_short_description()). Unit tests added.
Another hitchhiking change:
Add command mouse-click shortcut to help output on TensorFlow runtime errors (in cli_shared.py: get_error_intro())

This is the first pass at adding mouse support to tfdbg CLI. It focuses on the analyzer part of the CLI. All these changes are backward compatible, in the sense that all keyboard commands continue to work as before.
* The list_tensors (lt) command now has hyperlink-like clickable text in its output, which users can use to navigate to the tensor value display with only one click.
* The outputs from all analyzer commands (lt, pt, ni, li, lo) have a main menu displayed near the top, right below the title bar. The menu contain items such as list_tensors, node_info, print_tensor, which get enabled and disabled properly depending on the context.
Also in this CL:
* Let users print tensors using the node name (instead of the tensor name), if the node has generated only one dump from one output slot.
Change: 142605017
This check-in implements the following commands (and aliases) in the stepper CLI:
* cont (ct, c)
* step (st, s)
* list_sorted_nodes (lt)
* print_tensor (pt)
* inject_value (inject, override)
To activate the stepper CLI, enter command "step" or "s" at the run-start CLI.
Not implemented yet:
* Documentation in g3doc/how_tos/debugger will be submitted in a later CL.
* Commands for inspecting node information and graph structure in the stepper CLI, including ni, li and lo.

1. Make the BaseDebugWrapperSession class capable of working as a context manager, as the non-debug Session. Also let the wrapper class support the close() method.
2. Handle the case in which a fetch is an object without the "name" attribute, e.g., a SparseTensor.
Change: 141308246
Before this CL, there are two CLIs launched for each Session.run() call: the run-start CLI and the run-end one. They have different sets of commands, which is potentially confusing. This CL consolidates the two.
* The run-start CLI is launched only before the first Session.run() call.
* In subsequent Session.run() calls, only the run-end CLI is shown. At this CL, the same "run" command as in the run-start CLI works.
* Added the "-t" option flag to the "run" command to allow running through a number of Session.run() calls without pausing at the CLI.
* Adde the "run_info" (shorthand: "ri") command to allow inspection of the run fetches and feeds.
* Added more unit test coverage for the LocalCLIDebugWrapperSession class.
* Made corresponding doc updates.
* Added "tfdbg" logo to the "splash screen" of the CLI.
Change: 141221720
1. Refactor the code in local_cli_wrapper.py for generating introductory messages about the run() call and the TF runtime error to functions in a new python file: cli/cli_shared.py
2. Make the introductory message-generating functions capable of handling nested lists, tuples, dicts and namedtuples as the fetches of run() calls.
3. Use bold font attribute to highlight suggested commands in the introductory messages.
4. Minor tweaks to the title bar color.
5. Minor doc fixes in examples/README.md.
6. Add new font attribute "blink" to curses_ui.py and let the error title message use that attribute.
