Plots example (Plots.ipyenb) fails on mybinder
aokomoriuta opened this issue ยท 9 comments
https://mybinder.org/v2/gh/robert-dodier/maxima-jupyter/master doesn't show the result plots.
Restarting the kernel says FILE-DOES-NOT-EXIST: The file #P"/tmp/maxplot.svg" does not exist: No such file or directory.
The problem seems about write-permission on /tmp? But set_plot_option([svg_file, "./maxplot.svg"]); causes same error.
How can I fix it?
Thanks for your message. What does build_info(); report?
Try changing contour_plot in the notebook to the suggested plot2d([contour, ...], ...) and evaluate that. Does that succeed?
build_info();
says:
build_info( 5.45.1 , 2021-12-11 13:09:55 , x86\_64-unknown-linux-gnu , SBCL , 2.1.11 , /home/jovyan/.maxima , /tmp , /home/jovyan/.maxima/binary/5\_45\_1/sbcl/2\_1\_11 ,๐๐๐ฅ๐ฌ๐,๐๐๐ฅ๐ฌ๐)
The error occurs for all plots but not only contour_plot. For example:
plot2d (sin(x), [x, -%pi, %pi])$

You can try and debug with https://mybinder.org/v2/gh/robert-dodier/maxima-jupyter/master (same as the link on the top of this issue)
BTW, I got the error only on the binder service. My maxima-jupyter on my local machine works well and shows the plot result.
Thanks for the additional information. It looks like the problem is the /tmp directory since all plot functions are affected.
Is it possible that /tmp doesn't exist in the Binder environment? I don't know how to resolve that. @yitzchak do you have any ideas what to do about that?
What is a folder which is certain to exist in Binder? Maybe plot2d will succeed if you tell it to put outputs there.
I found the comment I wrote in the first is correct. It is not a problem about write-permission (file path to write), but about that Gnuplot is not installed on the binder.
After setting maxima_tempdir,
maxima_tempdir:"/home/jovyan/maxima-jupyter/examples";
set_plot_option([svg_file, "maxplot.svg"]);
plot2d (sin(x), [x, -%pi, %pi])$
maxout49.gnuplot is output on the current directory (maxima-jupyter/examples), but the SVG file maxplot.svg is not.
On the terminal launcher, I found
$ gnuplot
sh: gnuplot: command not found
Do you forget to install Gnuplot on the Dockerfile or somewhere the binder would need?
Additionally, I can confirm the correctness of the hypothesis if I can know how to check the output of gnuplot command from maxima.
I've pushed commit 588548 to modify Dockerfile to install gnuplot. Thanks for the reminder!
Now when I try to launch JupyterLab via mybinder.org, it successfully launches (installing gnuplot along the way as shown by the log messages), and I can start a Maxima notebook session, and some example operations (build_info, makelist, integrate, etc) succeed. But when I try plot2d(sin(x), [x, 0, 10]); it returns false and displays nothing.
Not sure how to figure out what is going on there. I think the notebook can display out-of-band messages generated by Maxima, so the absence of error messages makes me think there aren't any.
I just tested with Plots.ipynb and it seems to work in Binder.
Thanks for checking, Tarn. I find now that when I try the examples in Plots.ipynb that they work for me too; I think the key is to set the svg_file option. I'm going to go ahead and close this ticket as fixed by commit 588548.
Thanks for fixing it. Now I can execute Plots.ipyenb successfully with 588548e !
