Nbconvert: Config option `template_path` not recognized by `NotebookExporter`.

[joelostblom]

When I run jupyter nbconvert --to notebook test.ipynb, the following warning appears:

[NbConvertApp] WARNING | Config option `template_path` not recognized by `NotebookExporter`.

The notebook is still exported fine, but it would be nice to silence the warning if possible. It does not occur with any of the other export formats I tested (python, markdown, pdf, slides, html).

I don't think I have set template_path manually anywhere, grepping ~/.jupyter/ only shows a single commented out occurrence in jupyter_notebook_config.py (so not same as https://github.com/jupyter/nbconvert/issues/895):

150:# c.NotebookApp.extra_template_paths = []

I think this is already fixed in ~master~ 6.0.0a1 and possibly the 6.0.0a0 alpha release.

Thank you! I can confirm that the warning is gone on 6.0.0a1.

Issue still 6.0.7.

I met the same problem. I install nbconvert 6.0.7, but when I run jupyter-notebook and open a new notebook in the browser, there will be such kind of error in the terminal:

[W 23:12:49.294 NotebookApp] Config option `template_path` not recognized by `LenvsHTMLExporter`.  Did you mean one of: `extra_template_paths, template_name, template_paths`?
[W 23:12:49.322 NotebookApp] Config option `template_path` not recognized by `LenvsTocHTMLExporter`.  Did you mean one of: `extra_template_paths, template_name, template_paths`?

Then I reinstall nbconvert of version 5.6.1, then everything is OK!

conda install -c anaconda nbconvert=5.6.1
