In the first.tex, import a package "first.sty". I separate the macro package "first.sty" from first.tex base on latex3's l3build file structure. So I focus on coding the macro in "first.sty".
The issue is that the "\second" do not recognize. Maybe need more syntax here. I am not sure which syntax it is. Please help me fix that.

I have included the right packages etc.:
\usepackage{tikz}
\usepackage{pgfplots}
\pgfplotsset{width=10cm,compat=1.9}
% We will externalize the figures
\usepgfplotslibrary{external}
\tikzexternalize
I have also tried running it with things such as:
--shell-escape main.tex
--enable-write18 main.tex
or adding
\tikzexternalize[shell escape=-shell-escape]
But this does not seem to work, everything does work correctly when I e.g. open it in Overleaf.

I tried to recreate this instance. It first asked for the missing iopart.cls documentclass. I could get that from a GitHub repository belonging to Tianjin University named "etgroup". You can simply find it by searching "iop latex template" in Github. After the second compilation, it asked for a class dependency named iopart10.clo(it's available in the same repository).
Finally, after the third compilation, I could get a PDF output(Please see the figure attached).
Solution: If you are using a local LaTeX IDE/Studio, I recommend updating the packages you are using. Sometimes there are conflicts between some packages but they usually resolve quickly by releasing an update and you might see that there was nothing wrong with your commands.
Alternatively, you may try using an online LaTeX editor. They always have the last version of the most common packages and are equipped with multiple LaTeX render engine types.
Hi I'm using Overleaf for my dissertation and this warning started popping up recently:
Citation 'objprogen' on page 1 undefined on input line 8.
This citation is already created as seen below in the 'sources.bib' file:
#article{objprogen,
author={Guo, Wenzhong and Lin, Renjie and Wang, Shiping and Xiong, Neal},
booktitle={2018 9th International Symposium on Parallel Architectures, Algorithms and
Programming (PAAP)},

year={2018},
volume={},
number={},
pages={235-242},
doi={10.1109/PAAP.2018.00046}}
This is my main.tex file:
\documentclass[a4paper]{article}
\usepackage{blindtext, graphicx}
\usepackage{csquotes}
\usepackage[hidelinks]{hyperref}
\usepackage{url}
\usepackage[style=authoryear-ibid,backend=biber]{biblatex}
\hyphenation{op-tical net-works semi-conduc-tor}
\bibliography{sources.bib}
\begin{document}

\input{includes/07-Appendix}
\end{document}
I had the same problem and solved it by adding \bibliographystyle{plain} (of course you could in principle use other styles). For me the structure of the tex file is the following
\documentclass[oneside, a4paper, onecolumn, 11pt]{article}
%%some packages%%
\begin{document}
%%% some stuff
\bibliographystyle{plain}
\bibliography{bibfile} %bibfile name without the .bib extension
\end{document}
So contrary to you the \bibliography is also inside the document environment.
When my Markdown file contains a horizontal rule --- or *** I receive an error regarding \Linethickness -> \Protect
I understand there have been issues with MiKTeX recently, however I am unsure whether they apply here.
I have been experiencing this issue since yesterday morning, when I was playing around trying to get the Lato font package to work with a set of Markdown files I need to convert to PDF. It had been working fine (asides from the font issue).
This could have happened when I updated MiKTeX, although at the time I hadn't realised that could be the case, as I was also playing with the templates, YAML, PS Script etc.
Since then I've been reading about the MiKTeX issue and I've tried further updates, updating package database, building formats, refreshing file name database and uninstalling and reinstalling. I have read the background in the comments section on GitHub but the suggestions there do not seem to have solved it for me, whereas they have for others.
This makes me question whether this is related, but I am relatively new to Tex, Markdown etc.
The original file was longer and more complex, but this Markdown
# Sample File
Test Test Test
---
Produces the same error
Error producing PDF.

<to be read again>
\protect

\relax
\#rule ...#tempdimb {#2}\setlength \#tempdimc {#3}
\advance \#tempdimc \#temp...
l.362 ...nter}\rule{0.5\linewidth}{\linethickness}
Removing the --- allows the pdf to generate in both the above example and my more complex markdown file, even with templates.
I am unsure if linethickness is within the graphics package, when I look at package information I can't see anything that obviously indicates it is.
I would simply remove the offending lines but they are used throughout the remainder of the markdown files and I would prefer to find a fix, with your help, if possible!
Please could you let me know if I'm barking up the wrong tree with this recent MiKTeX issue or not, and if not, where I might be going wrong.
Many Thanks in advance.

I ran this command
pandoc -s sample.md -o sample.tex

meanwhile, I tried this (as root in a latest RStudio Debian install):
~# sed 's,\\linethickness,0.5000000000pt,g' < pandoc/pandoc > /usr/lib/rstudio-server/bin/pandoc/pandoc
where the 1st pandoc/pandoc is a copy of the original from package. That keeps the same string length and valid number so that the binary won't break. That writes the hrule as:
\begin{center}\rule{0.5\linewidth}{0.5000000000pt}\end{center}
and MiKTeX seems fine with it (at least TeXworks compiles the pdf).
HTH

Is it possible to write LaTeX in jupyter? It seems that IPython.display.Latex supports only a subset of LaTeX equations. In particular I would like to use \tabular and others LaTeX commands (HTML is not an option).
You should have a look at the latex_envs extension in https://github.com/ipython-contrib/IPython-notebook-extensions (install from this repo, it is the most recent version -- follow the instructions in the README). Some documentation here https://rawgit.com/jfbercher/latex_envs/master/doc/latex_env_doc.html
I recently tried this in Jupyter Lab. Mark a cell as "raw". Then:
%%latex
\bf{This is a test} \\
It allows latex $\alpha=\beta$ and test:
\begin{equation}
\alpha = \beta
\end{equation}
% this is a latex comment
Then File -> Export Notebook as -> PDF
