Multiple errors occur when building tensorboard from source.

[rgkannan676]

Hi All,

I am trying to build tensorboard from source(https://github.com/tensorflow/tensorboard.git) with steps as mentioned in https://github.com/tensorflow/tensorboard using bazel(bazel 3.7.2) in Windows 10. But I am facing multiple issues.

->bazel build tensorboard:tensorboard

"/logo/favicon.png': No such file or directory". To fix this issue, I removed the following entry causing the issue from tensorboard/tensorboard/webapp/BUILD file

genrule(
    name = "gen_index_polymer3.html",
    srcs = ["index_polymer3.uninlined.html"],
    outs = ["index_polymer3.inlined.html"],
    cmd = "$(execpath //tensorboard/logo:inline_favicon) $< >$@",
    tools = ["//tensorboard/logo:inline_favicon"],
)

After cleaning(>bazel clean --expunge) I ran the build again. This time new issue occurred.

Error suggests another missing file.
I tried using old versions of source code, but faced multiple issues including Circular dependencies. Please advise how to resolve the issues.

The second missing file input is because you remove the genrule gen_index_polymer3.html which generates the file index_polymer3.inlined.html needed as the source for tensorboard-webapp. Why you do not have that genrule executed correctly is what you want to look into.

1. Could you verify in your sourcecode, whether tensorboard/logo folder exists and what is the folder structure? (Is favicon.png there?)
   (https://github.com/tensorflow/tensorboard/tree/master/tensorboard/logo)

2. Could you try run that genrule
bazel build tensorboard/webapp:gen_index_polymer3.html
   and check if any error and if you have index_polymer3.uninlined.html generated?

To add to the above comment, building TensorBoard from sources in windows is not well supported. TensorBoard pip package is supported in Windows at our "best effort". Not all features work on Windows (e.g. rustboard data server) and we try to fix any raised issues case by case when something is broken and reported.

Close this issue. Feel free to reopen if you have more questions.

Hi,
Thank you for the response.

1)favicon.png is present in the folder tensorboard\tensorboard\logo

2)I tried to run the genrule as suggested. But got error the following error.

• I have one more doubt. I am trying to make some changes and deploy the tensorboard embedding projector. Can you please suggest if I can build and use only that functionality. I tried to run bazel run tensorboard/plugins/projector/vz_projector:standalone as suggested in https://github.com/tensorflow/tensorboard/tree/master/tensorboard/plugins/projector. But got the following error.

D:\tensorboard>bazel run tensorboard/plugins/projector/vz_projector:standalone

Please advise.

I tried building in Ubuntu(Ubuntu 18.04.5) using Windows Subsystem For Linux(WSL) . But received a similar error

Hi @japie1235813 @arghyaganguly . Can you please reopen the issue. Thanks

[japie1235813]

We can re-open the issue, but can't provide much further assistance here since the windows build for TensorBoard has never been officially supported (including WSL).
If you identify patches that would get things working, we're happy to review them.

Also, while I'm glad you're excited about the projector visualization, we also don't explicitly support the standalone mode - you're welcome to try to get it working but I would not suggest relying on it long term.

As for the error message you provided, there is a missing slash, it might be something to do with how Windows (or WSL) compose the filepath.
(It shows ...logo/inline_favicon.runfilesorg_tensorflow_tensorboard/tensorboard/logo/favicon.png but we expect something
...logo/inline_favicon.runfiles/org_tensorflow_tensorboard/tensorboard/logo/favicon.png
Again we will not look into the details.

Hi @japie1235813 ,

Thank you for looking into the issue. I was able to build successfully in Ubuntu 20.04.2.0.

Projector visualization is a very cool feature. I have an ER, will it be possible to allow the user to see their 3-Dimensional data without applying any dimensionality reduction techniques. This will allow the user to experiment with other techniques than the offered ones.

I will close the issue. Thank you for the support.

Yes, we have a longstanding feature request for this: #1192 (and also somewhat #1204)

I agree it would be useful, but we haven't had bandwidth to look into this area.
