Tensorboard: SVG Export Problem

[k-zen]

When exporting/downloading a TensorBoard graph in SVG I get the following incomplete file. If it's any help, the data in the graph I'm trying to export corresponds to scalar values generated using TensorBoardX.

Info:

• TensorBoard 1.12.2
• TensorFlow 1.12.0
• macOS 10.14.3
• Python 3.6.6
• Chrome 72.0.3626.109

Can you include a screenshot of the chart as you see it in TensorBoard, and if possible the event files that you're loading that data from?

@stephanwlee any ideas?

Repasting the contents of your SVG file for ease of reference, with newlines inserted between tags for readability:

[wchargin]

It is interesting that in both your example and [this comment on

1446][1], the file is clipped at the first instance of url(, even

though these prefixes have different lengths: 5525 bytes in this issue,
4481 bytes for that one.

Both on macOS, though the other poster is on Safari.

Can you include a screenshot of the chart as you see it in TensorBoard, and if possible the event files that you're loading that data from?

Sure!

I got the same problem if the tensorboard is launched from remote host, the svg file seems incomplete. It works fine when i start it from my mac. Didn't know why.

Looking at the code a little bit, I think that the issue prior to #1601
was that the exported SVG string can include a hash, which is likely
treated as a fragment specifier in the URL, thus truncating the path:
https://github.com/tensorflow/tensorboard/blob/23b6bcdeb9f17f1c5531ed8007d79173d5176afd/tensorboard/components/vz_line_chart2/line-chart-exporter.ts#L69-L70

This explains why the OP in this thread and the [original reporter]
observed an SVG that stopped exactly at clip-path="url(, despite that
the truncation is otherwise unrelated (e.g., at different offsets). This
also explains why #1601 presumably fixes the problem (that pull request
does not have a description or test plan, so it’s hard for me to infer
the full context, but I assume that @stephanwlee was able to reproduce
the problem and confirm that it was fixed after that commit).

I don’t have @Flowerfan’s SVG file, but the “AttValue: ' expected”
message sounds consistent with this hypothesis.

The fix in #1601 did not make it into 1.12.2, which also explains why OP
sees the problem. @k-zen could you try upgrading to 1.13.1 and checking
whether the problem recurs? (Please note that tensorboard>=1.13.0
strictly requires tensorflow>=1.13.0 as well.)

I’ll update the comment in the code make it clearer why the base64
encoding is necessary.

[wchargin]

Simple repro: https://gist.github.com/wchargin/f644d584ddafb19d003d46084c0f80e5

See #1971.

[wchargin]

Ah, @nfelt points out that Firefox’s interpretation is the correct
one; this was a bug in Chrome until Chrome 72. Opening such a truncated
SVG in Chrome 72 gives me exactly the AttError message that @Flowerfan
reports.

[Flowerfan]

TF 1.3 solves the problem. It works fine in Chrome 72. Just tested. Thanks, @wchargin.

[wchargin]

Glad to hear it; thanks for confirming!

[k-zen]

I can confirm. It is solved in TF/TB 1.13.1 when exporting from Chrome 72.0.3626.109. Thanks @wchargin!

[wchargin]

Great; thanks!
