Nbconvert failed index.tex.j2

[LeTrongDat]

I followed the instructions in this documentation: https://nbconvert.readthedocs.io/_/downloads/en/5.2.1/pdf/. But when I use jupyter nbconvert --to pdf Mynotebook.ipynb I get the error

[boileaum]

Template names have been renamed since nbconvert 6.0: .tplx extension has been replaced by .tex.j2. Your installation seems inconsistant.

You may try to upgrade your nbconvert version to >= 6.0, for example using:

pip install -U nbconvert

I tried the pip install -U nbconvert but it didn't work. I'm getting a similar error File "C:\ProgramData\Anaconda3\lib\site-packages\jinja2\loaders.py", line 497, in load raise TemplateNotFound(name) jinja2.exceptions.TemplateNotFound: index.tex.j2

[LeTrongDat]

This is nbconvert version on my laptop. But it still doesn't work.

[boileaum]

Did you test this in a virtual environment? May be some versions of jupyter packages and nbconvert are not compatible in your current installation.

These bash commands:

• exclude default JUPYTER_CONFIG_DIR to prevent from loading personal settings
• convert notebook to html

Works well on my Mac.

Same here

In the meantime, my workaround was installing MikTex (since I'm on Windows) and then installing jupyter in a virtual environment and exporting a latex file from jupyter notebooks.

Then I ran the following command from powershell:

xelatex 'Put your file name here'

Here's another alternative, it seems basically the same as converting to html and then using the print-> save as pdf feature: https://towardsdatascience.com/jupyter-notebook-to-pdf-in-a-few-lines-3c48d68a7a63

You can also export as markdown and then convert it following this page's instructions: https://gist.github.com/justincbagley/ec0a6334cc86e854715e459349ab1446

Same issue with nbconvert

Python 3.9.1, pip 21.01.1

Is it normal that when I launch ''pip install nbconvert'' there is nothing in the ''templates'' directory?

[MSeal]

Is this with a conda environment, a virtual environment, or system python? It seems like templates are not getting installed alongside the library through some installation path.

Is it normal that when I launch ''pip install nbconvert'' there is nothing in the ''templates'' directory?

No it should have templates present in your environment's share/jupyter/nbconvert/templates/ directory. I just tried a fresh 3.9 venv and didn't hit any issues installing nbconvert with pip.

[carobizbiz]

No it should have templates present in your environment's share/jupyter/nbconvert/templates/ directory. I just tried a fresh 3.9 venv and didn't hit any issues installing nbconvert with pip.

I found the templates eventually in my ''C:/users/.../AppData/Roaming/Python/share/jupyter/nbconvert''. The nbconvert log never specified this path in its degub.

Copy pasting the templates in ''C:/users/.../AppData/Roaming/jupyter/nbconvert'' solved the issue for me.

I don't understand why the Roaming/Python/jupyter folder is not found when I launch nbconvert, and vice versa why this Roaming/jupyter folder exists.

I tried this approach to download pdf via latex but I'm getting the error below:

nbconvert failed: PDF creating failed, captured latex output:
Failed to run "xelatex notebook.tex -quiet" command:

has anyone had the same issue? I think it's relate to latex itself. Since I could download the zip and run it and compile it on overleaf.

Python 3.9 from MS Store

jupyter core : 4.7.1 jupyter-notebook : 6.3.0 qtconsole : 5.0.3 ipython : 7.22.0 ipykernel : 5.5.3 jupyter client : 6.1.12 jupyter lab : 3.0.14 nbconvert : 6.0.7 ipywidgets : 7.6.3 nbformat : 5.1.3 traitlets : 5.0.5

[nleroy917]

Still having this issue too. Fresh install's inside a virtual environment do not help. I must specify nbconvert==5.6.1 in requirements.txt file to get it to function.

[wang-yiwei]

For the linux user:

I am inspired by the method proposed by carobizbiz, there must be some missing template files in the directory where the command jupyter nbconvert --to xxx --template xxx tries to get access. If we can find the directory contains the template files and copy-paste them into the target directory, the problem should be solved.

❯ python --version
Python 3.10.8
❯ jupyter --version
Selected Jupyter core packages...
IPython          : 8.4.0
ipykernel        : 6.15.2
ipywidgets       : 8.0.2
jupyter_client   : 7.3.5
jupyter_core     : 4.11.1
jupyter_server   : 1.18.1
jupyterlab       : 3.4.8
nbclient         : 0.6.7
nbconvert        : 7.0.0
nbformat         : 5.4.0
notebook         : 6.4.12
qtconsole        : 5.3.2
traitlets        : 5.3.0

I used a virtual environment with the last proper functioning version nbconvert == 5.6.1 and did some experimental tricks and finally found out the location of these files in the non-virtual python environment: /lib/share/jupyter/nbconvert/templates/latex, which should be a generic path for linux systems.

The target folder for the command line should be /lib/YOUT_PYTHON_VERSION/site-packages/nbconvert/templates (e.g. the path on my machine is: /lib/python3.10/site-packages/nbconvert/templates. Correct me if yours is different). Then COPY + PASTE all the template files from the first path into this (almost) empty one with GUI or Terminal.

Then your command line jupyter nbconvert --to xxx --template xxx shoud work now, at least on my machine, it went as well as nbconvert <= 5.6.1

[j-bowhay]

Same issue here

[geeshta]

I'm having the same issue. I tried using both a virtual environment (with Poetry) and a system-wide installation.

In the virtual environment, I see the templates in .venv/share/jupyter/nbconvert/templates In the system-wide installation I see them in /usr/share/jupyter/nbconvert/templates

However none of these work and I'm getting the same error as others. I tried copying them to /usr/lib/python3/dist-packages/nbconvert/templates and to /usr/local/lib/python3.10/dist-packages/nbconvert/templates

I also the in the virtual environment to .venv/lib/python3.10/dist-packages/nbconvert/templates and running the command with a venv shell but no matter what I try I always get the error TemplateNotFound(name) jinja2.exceptions.TemplateNotFound: index.tex.j2
