Failure generating a pdf of the documentations using make latexpdf

### Describe the bug

Hi sklearn team and fans,

I am trying to generate a pdf of the documentations to be able to read/use sklearn documentations offline. On multiple systems ranging from Macos (ARM or AMD processors) to Ubuntu, I am facing this issue and I am unable to troubleshoot it further:

```
Configuration error:
There is a programmable error in your configuration file:

make: *** [latexpdf] Error 2
```
First, are we able to utilize the `make latexpdf` to automate the generation of a pdf for the entire documentation? If no, just indicate so. If yes, then, how would you recommend I resolve ot troubkeshoot this issue further? As you can see, the error trace poitns to multiple files in sklearn and I thought I can bring this issue up.

Thanks and best regards

### Steps/Code to Reproduce

```
pip install sphinx sphinx-gallery numpydoc matplotlib Pillow pandas scikit-image joblib
cd doc
pip install --editable ..
make latexpdf
```


### Expected Results

Update:
following the snippet above enabled `make latexpdf `to conclude successfully.

Here is the tail of the output:

I navigated through _build/latex but can not see any pdf file. Please let me know if there is anything that I am missing on.
