ValueError: invalid literal for int() with base 10

[dege13]

I keep hitting this error with several books. Any ideas what is wrong?

Using the command python main.py --tts edge

Running on Windows.

I also have these warnings before the processing happens, but some books do succeed so I don't think these warnings should actually matter.

I found an copyright free example epub that causes the error. Feel free to use this one to reproduce the issue, or if it is environmental, maybe you will not get the error. famouspaintings.zip Found another free sample epub which also demonstrates the issue: internallinks sample.zip

I managed to fix it. In the file: epub_to_audiobook/audiobook_generator/tts_providers/edge_tts_provider.py

I added a try except block around the int parser, and now it doesn't crash:

    def parse_text(self):
        if not "[pause:" in self.text:
            return [(0, self.text)]

        parts = self.text.split("[pause:")
        for part in parts:
            if "]" in part:
                pause_time, content = part.split("]", 1)
                try:
                    yield int(pause_time), content.strip()
                except ValueError:
                    yield 0, content.strip()

            else:
                content = part
                yield 0, content.strip()

Thank you @LarsHLunde, haven't got chance to test dege13's doc. However, it worked perfectly on my books, which are failing before the fix.

Hello, I ran into this problem with edge on Windows and MacOS, but it was not an issue when using docker. I did some investigating which may be interesting or useful, before finding this issue with your solution.

The docker uses python 3.11 so I thought that might be it, but forcing python 3.11 on MacOS still resulted in the same error.

The contents of edge_tts_provider.py is identical in the docker.

Here are the different modules, where docker is using the older version, so probably one of these is to blame.

The fix from @LarsHLunde works for me. I'm guessing it breaks when the text itself has a ] in it maybe? Something like this could be a fix? (not proper code just expressing the idea)

    match = re.search(r'\[pause: ([^\]]+)\]', self.text)
    if match:
        x_part = match.group(1)
        rest_of_string = s[match.end():]  
        # recursively apply this to rest_of_string 
    else:
        yield 0, s

Also I'm confused because the comment on the code says

    # This class uses edge_tts to generate text
    # but with pauses for example:- text: 'Hello
    # this is simple text. [pause: 2s] Paused 2s'

But that example would throw an error when it tries to do int('2s'). So maybe I am misunderstanding the code somewhere.

Just made a new release to address issues related with edge tts feature. https://github.com/p0n1/epub_to_audiobook/releases/tag/v0.6.0 It would be great if anyone in this issue to try it out and let me know if it's working.
