Error with Python3.10

[paubanon]

I'm trying to convert a manga to read it with my Kindle Oasis but it keeps popping the same error. I've tried converting to cbz, change images format, pdf, ... And always get the same error, so I guess there must be something with the images (although I can see them perfectly on the computer.

One of workers crashed. Cause: 'float' object cannot be interpreted as an integer
Traceback:

I'm getting the exact same error on Fedora 36 with pillow 9.2.0.

Pillow >= 8.4.0

Duplicate of #406

I was getting the same error, even with Pillow and Slugify installed:

$ pip3 freeze | grep -i -E "(pillow|slugify)"
Pillow==9.2.0
python-slugify==2.0.1

However I was using the Flatpak version. Now, I cloned the repo and ran it on terminal, everything works as expected.

$ python3 kcc.py

I'm using Linux Mint 21. Hope this helps.

I'm also using KCC 5.5.2-6 Flatpak version but still got error with python-3.10. I read your solution but unable to know how to use.
Hope you could explain more in detail. I really would like to make KCC work in Linux Mint 20.3.
Thanks a lot!

Hi @hhtien1408,

Sure, here are the steps that I've done:

1. First, I removed the flatpack version from my computer.
2. Next, I downloaded this repo by running

$ git clone https://github.com/ciromattia/kcc.git

3. Then I installed the necessary packages. You can do it by running the following command. The requirements.txt file is inside this repository, you will see it when you clone the repo.

$ pip3 install -r requirements.txt

4. This should install the packages mentioned in Work-around to "RuntimeError... 'float' object cannot be interpreted as an integer during execution" for kcc-c2e.py powershell/CLI #406. You can check the version by running

$ pip3 freeze

If the packages are in the wrong version, you can try to upgrade them by running

$ pip3 install --upgrade name_of_the_package

5. Now, it should be all done. You can go to the folder of this repo and run

$ python3 kcc.py

If everything goes well, you now should be able to use it. However, if you are still seeing the same error, you can try to change the code mentioned in #406. Go to line 258 of kcc/kindlecomicconverter/image.py file and change it with the following line:

self.image = ImageOps.autocontrast(Image.eval(self.image, lambda a: int(255 * (a / 255.) ** gamma)))

I didn't have to do this modification, just installed the right packages was enough. But maybe you could try it aswell. Hope this helps!

Hi @hhtien1408,

Unfortunately, I can't help you with that, I didn't test it on Windows or macOS, only Linux. I think it's possible to use an Ubuntu docker image and install kcc inside of it, but I won't be able to help you with that.

Hi @hhtien1408,

I didn't try to fix the package myself, instead, I cloned this repo and run it manually. I'm not sure if it's possible to fix the packager or not.

@hiagofranco I managed to make it working under Linux Mint 20.3 with your guide and some extra steps by myself to make life easier.

If you would like to try KCC v5.5.3-beta-darodi.6
$ wget https://github.com/darodi/kcc/archive/refs/tags/v5.5.3-beta-darodi.6.zip
$ unzip v5.5.3-beta-darodi.6.zip
Rename folder 'kcc-5.5.3-beta-darodi.6' into 'kcc' for convenience.

Download and copy kindlegen into '/usr/local/bin' and grant execute permissions for MOBI conversion.
$ wget https://archive.org/download/kindlegen_linux_2_6_i386_v2_9/kindlegen_linux_2.6_i386_v2_9.tar.gz
$ unzip kindlegen_linux_2.6_i386_v2_9.tar.gz
$ sudo cp -R '/home/h2t/Desktop/kindlegen' '/usr/local/bin'
$ sudo chmod +rwx '/usr/local/bin/kindlegen'

Create destop file in '/home/h2t/.local/share/applications' with codes:

#!/usr/bin/env xdg-open

[Desktop Entry]
Type=Application
Name=Kindle Comic Converter
Icon=kcc
Exec=python3 '/home/h2t/kcc/kcc.py'
Terminal=false
StartupWMClass=kcc
Name[en_US]=Kindle Comic Converter

Copy icon file into '/home/h2t/.local/share/icons'

$ sudo cp -R '/home/h2t/Desktop/kcc.png' '/home/h2t/.local/share/icons'

It worked flawlessly with KEPUB conversion for my Kobo Aura One and MOBI for KPW3 from CBZ (with full metadata and TOC using ComicInfo.xml method).

Your help is highly appreciated!

@hiagofranco @hhtien1408 Thank you very much! It works perfectly now :D

I can't reproduce on the flatpak version.
