No static plots are saved due to some kaleido problem

Hello, I tried using NanoPlot this morning and it works perfectly. But when I try to reproduce my work this evening, it shows this error.

I'm running NanoPlot on a WSL with Ubuntu 20

Hi,

Is there a difference in internet connection/firewall between the morning and evening test? Regardless of the error, the HTML output should be created, but the (identical) PNGs would be missing.

I think what's different with the internet connection is the latency. Just now I try it once again and it shows a different error.

If you read this then NanoPlot 1.38.1 has crashed :-(
Please try updating NanoPlot and see if that helps...

If not, please report this issue at https://github.com/wdecoster/NanoPlot/issues
If you could include the log file that would be really helpful.
Thanks!

When this error comes up the HTML output is not created, it's just the log file in the output folder.

NanoPlot v1.39.0 has a --no_static option and should be available through pip now and through conda soon, in case you don't want the png images or have trouble generating them.

[awgymer]

I am having this issue too and I think it may be due to a firewall on the cluster where it runs (which I am unlikely to be able to change). Is there any recommended workaround or solution besides the --no-static option?

[drchriscole]

I'm having the same issue. I agree with @awgymer is another solution possible? Previous versions of NanoPlot don't seem to have this problem.

OK it seems my issue with NanoComp is stemming from the NanoPlotter / NanoPlot. It be great to export static plots for presentations. It's a bit of a faff to open the HTML plotly and export each time. https://github.com/wdecoster/nanocomp/issues/53#issue-1199060875
