Error: Could not save view.

[jjerry-k]

Hi, I'm Jerry.

When I view my metrics on my project page, I got an error message like "Error: Could not save view." on the web page.

Can you tell me about the situation that can cause this error?

Is it about db connection?

Hi @jjerry-k, thanks for reporting this! Would you mind sharing with me a link to the page where this issue is raising? Also, have you tried other browsers, clearing cache/cookies and incognito window to see if the same error appears?

Hi @jjerry-k, I wanted to follow up here! If this issue is still appearing, would you mind sharing with me a link to the Workspace and try other browsers, clearing up cache/cookies and incognito window?

Hi @luisbergua, Sorry, about the late reply. I tried several ways that using another browser and clearing cache/cookies. But, didn't repair. So, I want to get about wandb local web page's log. Could you explain where the log saved

[luisbergua]

Hi @jjerry-k, thanks for your answer! So this error could happen if the view exceeds a certain size threshold, could you explain me what's the size of the metrics? Also, are you running this by using wandb local? And could you send me a sudo code of how are you logging your metrics?

[jjerry-k]

Hi @luisbergua, thank you for your reply! I'm running wand by using docker! First, I'm logging 2029 items for each run with 40 epochs.

metrics = {
... 2029 items
}
wandb.log(metrics)

While looking at the log files, I got this message in mysql.log file.

2022-12-29T01:02:58.101968Z 22452 [Note] Aborted connection 22452 to db: 'wandb_local' user: 'wandb_local' host: '127.0.0.1' (Got an error reading communication packets)

Did mysql's max_allowed_packet option change when 0.9.40 to 0.9.49 was released?

[jjerry-k]

I solved this issue.

There was no max_allowed_packet option in the mysql configuration file.

Hi @jjerry-k, thanks a lot for sharing this! You can check the changes in the different releases here, I cannot see any changes regarding max_allowed_packet. Let me know if I can help you in any other way!
