make_pdf.py cannot find riemann.tex

Hi, when I try to generate a PDF, it runs almost until the end but I get the error below,

...

! I can't find file `riemann'.

If I'm not mistaken the code is supposed to create a riemann.tex but it is also trying to read it before it creates it? Is there a bootstrap riemann.tex file that I need?

Apart from this error, I am able to run the notebooks on their own without any problems (except, partially, the claw code, it generates the graph but doesn't animate)

Thanks,

Sorry, I think the software requirements for making this work are not well documented and now even I don't recall everything that is required. But I think you need to install Inkscape:

FileNotFoundError: [Errno 2] No such file or directory: 'inkscape': 'inkscape'

nbconvert uses inkscape to do some image conversion (svg to pdf).

[maojrs]

Indeed, it seems you are running into an error when running fix_latex_file.py, which assumes riemann.tex has already been created, but riemann.tex is not being created in the first place. I think nbconvert might have an inkscape dependency, so I agree with @ketch , to try to install inkscape.

If you elaborate more on not being able to run the claw code in the notebooks, maybe we can help also with that.

@ketch @maojrs Thanks for your answers, I install inkspace that error went away.

Now I have a different one, it says can't find riemann.tplx this file exists under build_pdf but it is not picked up for some reason. I copied it one level up, still same problem.

We didn't document the pdf build process very well in part because we didn't intend for users to build the pdf -- if you want the hard copy you should really buy the SIAM book (or perhaps access the ebook through your library), since they kindly gave us permission to share the notebooks and html files free of charge, but not the pdf.

Also it was quite a complicated procedure to get things fixed up to the format they needed for typesetting, and many of the changes we made were done by hand and/or ended up on a private branch. It was also rather fragile in terms of some of the underlying software changing, so I'm not sure we could reproduce the pdf file ourselves at this point. Sorry!

[burakbayramli]

Dr. Leveque, thanks for the response. I managed to generate .tex from Jupyter UI for every ipynb, ran pdlatex on them and collated the PDFs. For different type of output I printed to PDF on notebooks themselves; this will work fine. Thanks for making such a great book available.

[rjleveque]

Yes, that's a good way to get a pdf out of the notebooks, glad to hear it gave something useful.
