Hi @djbhalodiya, thanks for the bug report! Just to be sure I understand, did the extension report a successful export attempt even though the exported PDF was empty? What did the notebook that you were exporting look like?

Even with the most simple of notebooks, e.g. helloworld, I'm also getting what looks like a successful PDF export but file size is 0 bytes.

Stable VSCode 1.48, latest Python extension, Windows 10 and Tex is installed.

frederickjjoubert · 2020-08-18T14:48:57Z

Hi all, I'm getting the same problem. I am trying to export my *.ipynb (Jupyter Notebook) but the PDF exported with 0(zero) file size.

There is no export errors from VSCode, it looks like it's exporting successfully.

Also VSCode 1.48, Microsoft Python Extension v2020.8.101144, Windows 10 Pro v19041.450.

dpizzino · 2020-08-19T16:55:52Z

Same issue. Exporting a *.ipynb to a PDF results in a 0 byte file that cannot be opened. No errors from VSCode.

VSCode 1.48, Microsoft Python Extension v2020.8.101144, Windows 10

tomyummmm · 2020-08-27T12:28:02Z

Same issue faced for both html and PDF export. Both output is 0 byte file.

VSCode 1.48.2, Microsoft Python Extension v2020.8.103604, Windows 10

nini074 · 2020-08-31T16:16:09Z

Experiencing the same problem: PDF export of notebook appears successful but the result is a 0 byte file that will not open.

VSCode 1.48.2, Microsoft Python Extension v2020.8.105045, Mac OS Catalina

rchiodo · 2020-08-31T17:17:48Z

Can somebody try this on the failing notebook? It should show why the PDF export is failing.

jupyter nbconvert file.ipynb --to pdf --output file.pdf

It looks like we only assume a failure (and show stderr) when the pdf is not created. If it's created with zero length we're likely masking the error.

Sorry for the trouble here. While we can't fix this issue as it's not in our codebase, we'll investigate providing more discoverable error information in an upcoming release. As a workaround, please consider exporting to html, then via Chrome or Edge (or probably other browsers) you can print the page to PDF.

It looks like we only assume a failure (and show stderr) when the pdf is not created. If it's created with zero length we're likely masking the error.

I ran the code in terminal and it works, the output of jupyter nbconvert pdf works as expected, like running the code in my cmd.

The problem here is the export function. It still outputs 0kb file.

edit: Also, VSC does not prompt for the user to install TeX, causing the error the other user faced above.
Is there a way to get terminal to show the verbose output of what it is doing? Like when i click on export to > pdf, i want to see whats it doing

AlexWithYou · 2020-09-08T01:37:52Z

I have same issue here. Even though HTML format works well, the pdf format failed

orion160 · 2020-09-08T04:20:05Z

It happens because to convert a jupyter notebook to pdf it needs pandadoc and latex installed in the system, so vs code should notify about the required dependencies.

tomyummmm · 2020-09-08T04:27:49Z

It happens because to convert a jupyter notebook to pdf it needs pandadoc and latex installed in the system, so vs code should notify about the required dependencies.

I do have both installed. Like i mentioned, VSCode DOES NOT notify when they arent installed. And the error of output to 0kb still occurs when using the export to function. When using nbconvert directly in terminal, it works as expected.

rchiodo · 2020-09-09T23:02:51Z

Note: We're not going to search for PDF dependencies. The fix here will simply be to list out the error when we get a zero byte PDF file.

Then you guys better update your documentation as well if you arent going to search and prompt the user to install TeX

JanHomann · 2020-09-11T23:32:21Z

Same here. Neither conversion to Python Script, HTML or PDF works. exporting to Python Script produces no code, and exporting to HTML and PDF returns empty files. The command jupyter nbconvert my_file.ipynb --to pdf --output file.pdf works and produces valid output.

rchiodo · 2020-09-11T23:44:23Z

If this command is working:

jupyter nbconvert my_file.ipynb --to pdf --output file.pdf

Then I would guess you're not using the same environment we're using.

Your best bet to reproduce the problem with the command line is to:

Run the 'Python : Create Terminal` command (this should start the same environment)
Then run jupyter nbconvert file.ipynb --to pdf --output file.pdf

Under the covers, our 'Export to pdf' is running that exact command.

JanHomann · 2020-09-12T00:02:36Z

Even when i do that, it still works.

If you install this build: https://github.com/microsoft/vscode-python/suites/1180411345/artifacts/17273285 it should at least show you the error we're getting.

If you install this build: https://github.com/microsoft/vscode-python/suites/1180411345/artifacts/17273285 it should at least show you the error we're getting.

I don't know how to install this and if installing this will screw up even more or change my configurations.

rchiodo · 2020-09-12T00:15:35Z

That's a vsix file. You can install it through the extensions tab by clicking on the three dots and picking 'Install from VSIX'. It's how VS code packages extensions.

It's an internal build so it could be buggy with other things but it won't change any config settings.

Once you're done trying it, you can uninstall it and reinstall the general release of the python extension again through the extensions tab.

JanHomann · 2020-09-12T00:22:30Z

Okay. Exporting as Python Script gives no error and the output is empty. Exporting to HTML or PDF now gives an error

Export failed. Export failed. Please check the 'Python' output panel for further details.

(yes, it writes export failed twice) and i can see something in the python console. Which is a lot of stuff, but essentially boils down to:

It looks like it is using the wrong environment.

It sounds like an environment issue if it works with the terminal. Does the terminal use that .venv too?

It's definitely the wrong environment. The terminal uses a different environment.

rchiodo · 2020-09-12T00:28:53Z

Ah okay. Looks like there's a bug with picking the interpreter to use. It's this code here:

    protected async getExecutionService(source: Uri): Promise<IPythonExecutionService | undefined> {
        const interpreter = await this.jupyterService.getSelectedInterpreter(); <-- This should be something different.
        if (!interpreter) {
            return;
        }
        return this.pythonExecutionFactory.createActivatedEnvironment({
            resource: source,
            interpreter,
            allowEnvironmentFetchExceptions: false,
            bypassCondaExecution: true
        });
    }

Thanks for trying that out. We should be able to fix this for more people now.

rchiodo · 2020-09-12T00:30:46Z

If it works with the terminal (like it does for @JanHomann ) you might be able to work around this by running 'Python : Select interpreter to start Jupyter' and picking the python interpreter you're using for your notebook.

That line of code I marked as incorrect is using the 'jupyter interpreter' when it should be using the matching interpreter.

JanHomann · 2020-09-12T00:31:14Z

I can confirm that when i pick that particular environment then

jupyter nbconvert heatmap_unequal_spacing.ipynb --to pdf --output file2.pdf

gives exactly the same Traceback.
Also, this is an environment that's just a dump. I don't even know why it switches to that one.

The above solved my issues, im able to output to pdf now. But the normal python extension will still masks certain errors, like having images in the notebook and export to a 0kb PDF file.

Expected:
Exporting to PDF should fail, and show the below error (taken from the output of your dev version of python extension), and not export to a 0kb PDF file. This is a nbconvert issue as far as i can tell. Any help would be appreciated.

Also, it seems that when using the export to pdf function in VSCode, it uses the temporary path of the file, which causes issues if there is markdown which contains images/paths like ![iris](image/iris.png) as the images cannot be accessed. Is it possible to point directly to the actual location of the file so it can find the images for output?

To avoid installing xelatex (TeX) you might want to try exporting to HTML and using your browsers "Print to PDF" feature.

Below is the path file used when running in terminal directly and outputs the pdf with images fine.

Anyone got this to work?

IanMatthewHuff · 2020-09-28T20:58:04Z

Validated. At least for the basic concept that we should not be masking the error when the export fails.

WenukaB · 2020-11-12T19:48:04Z

I have same issue here. Even though HTML format works well, the pdf format failed

I'm facing the same problem

rchiodo · 2020-11-12T20:08:33Z

@WenukaB your jupyter output tab should show you what the failure is. Generally for export to PDF you have to install extra software.

See this:
