As I do not personally use Linux, I can't offer support for it, but if anyone has problems with it, report the Linux-related bugs here, and let's hope some other Linux users can help out submitting fixes for those problems.

hi i tryed to install the pallaidium addon from latest main branch and i get this error when trying to install dependencies:

[tin2tin]

Try a vanilla version of Blender instead of UPBGE (I have no idea what changes are made in this fork of Blender).

[vuaieo]

hi ok i installed official blender and addon again and i get same messege i think:

[tin2tin]

As you know, I'm not on Linux. Do you feel up for getting your hands dirty? (I can tell you how to disable the subprocess.call([pybin, "-m", "ensurepip"]) line - which is nice to have - but not necessary)

[vuaieo]

absolutely !!! how?

[tin2tin]

In Blender Preferences, check this and save Preferences in lower left corner - burger menu:

In the tabs, click the + and add a scripting workspace:

Right click on the Pallaidium generate button, and select Edit Source:

In the Text Editor select __init__.py:

This is the (messy) source code of Pallaidium.

[tin2tin]

Now highlight the ensure pip related lines and comment them (so they'll become disabled):

Then save the script: Alt+S (keep the mouse cursor in the Text Editor area when saving with shortcut)

Hit F3 and type reload scripts (not strips!!!):

When you hit Return, Pallaidium will be updated with this change you made. And hopefully the error will be gone.

[vuaieo]

hmm wow cool thanks for this tutorial i did it and now the error is shorter, here the error now:

[tin2tin]

Does this location have a file called python? /home/vuaieo/Desktop/UPBGE_29_8_2024/4.3/python/bin/ If not, where is it?

[vuaieo]

yes there was but this python file is called "python3.11"

[vuaieo]

ok super cool finaly with your help we figured it out how to fix it. the solution wassuper simple actually:

1. follow the guide from tinwotin by commenting or deleting the code lines from 705 to 712 in the file: /home/vuaieo/.config/upbge/4.3/scripts/addons/Pallaidium-main/init.py

2. and then go to your blender folder for this file "/home/YourUserName/BlenderOrUPBGE/4.2/python/bin/python3.11" and copy and paste this "python3.11" file in same folder and rename it to just "python" and after that go in blender and click on install dependencies in user pref... well it worked for me here is the video how to do:

https://github.com/user-attachments/assets/2ff92fa8-2d2c-4de7-9bd3-8be1fe6ba901

[tin2tin]

Thank you. As 1 was probably because of 2, it may not be necessary at all.

[jurassicjordan]

I followed the workaround above and successfully (or at least I didnt get any errors after/while installing deps) installed the addon. I went ahead to test just stable diffusion XL and got the following error

[tin2tin]

@jurassicjordan Did you remember to restart after installing the dependencies? What is your Linux distro?

Googling this part: 'torch.utils._pytree' has no attribute 'register_pytree_node seems to indicate the transformers python lib does not have the right modules. And you could either need a newer version or an older version.

Currently, is the Pallaidium transformers version specified, because it works on Windows(and maybe on some Linux versions?): transformers==4.43.0

What you could do is to install this add-on: https://github.com/amb/blender_pip

Then type in "transformers" and click uninstall. And then click Install and not if it is a newer version being installed. Then restart, and check if it is working now. If not, you can try earlier versions, by writing like this syntax: transformers==4.43.0 and hit Install.

Here you can see the version numbers: https://pypi.org/project/transformers/#history

If you find a version number working for you, let me know (I do not run Linux myself).

[jurassicjordan]

I did restart after dependencies where installed. I also tried to install that addon, but Blender complained that there was no manifest. I’ll try installing it manually by unzipping into the addons folder and see if I can install that version of transformers

[jurassicjordan]

okay, managed to get the pip addon installed, and successfully installed transformers 4.43.0 but I'm still getting a...Slightly? differnent but same error I think?? see at the end of the error it says something about an undefined symbol. didn't say that last time:

All of the dependencies will be/are installed in the path in the last line. And something is conflicting. The first ting to try is to click uninstall dependencies. When finished delete all folders with starting with ~ like ~orch. Then start Blender and Install Dependencies.

[jurassicjordan]

now when you say delete folders starting with ~, are you refering to folders within the site-packages folder? because I just uninstalled deps, but there doesnt seem to be folders there with a tilde

[tin2tin]

Yes, this folder: /home/jordancruz/Tools/Blender-Versions/stable/blender-4.2.0-stable.a51f293548ad/4.2/python/lib/python3.11/site-packages/

If you like, you can join the Pallaidium discord (invite on main page). There is a Linux user there, who's got Pallaidium up and running. Maybe he can help you, too. (I do not have Linux)

Here is the translated text:

I would like to share my experience of installing Pallaidium on an Archlinux system. Following the instructions on the official page, I performed the following steps:

• Install git (if your system already has git, you can skip this step)
• Download the add-on: https://github.com/tin2tin/text_to_video/archive/refs/heads/main.zip
• Run Blender
• In Blender, install the downloaded add-on

However, upon attempting to enable the Pallaidium plugin, I encountered an issue due to a dependency on the aud library, which is not available in my environment.

That aud https://pypi.org/project/aud/ is:

Support for Python 3.8, 3.7, & 3.6

My Archlinux system has Python version 3.12, so perhaps aud is not necessary.

After some troubleshooting with guidance from ChatGPT and inspired by the post at https://github.com/tin2tin/Pallaidium/issues/105 from @vuaieo, I found a solution by commenting out the problematic line in the code.

Here's how:

• Navigate to the Pallaidium plugin directory:

  cd ~/.config/blender/4.2/extensions/user_default/pallaidium_generative_ai/

• Open the __init__.py file in a text editor and comment out the line importing aud:

  ...
  import os
  # import aud  # Adding a "#" before it makes it a comment, and the program will skip this line.
  import re
  ...

• Save the file and restart Blender. Now you should be able to enable the Pallaidium plugin without any issues.

But hold on, there are two more crucial steps regarding dependencies that need to be addressed after creating a virtual environment. This step is essential "to avoid disrupting the system's existing standard environment (at least that’s what ChatGPT says)."

• In the Generative AI add-on preferences, click the "Uninstall Dependencies" button (to clear out any incompatible libraries).

No response? According to the official instructions, you should restart Blender at this point.

Actually, a virtual environment should have been created before this step.

The so-called "virtual environment" refers to isolating another set of Python environments specifically for the Pallaidium plugin within a directory, separate from the system's standard environment.

Even if there was no response in the previous step, this next step is absolutely necessary, especially on an Arch Linux system where environmental requirements are very strict.

• In the Generative AI add-on preferences, click the "Install Dependencies" button. Without a virtual environment, you will encounter the following error:

  error: externally-managed-environment
  
  × This environment is externally managed
  ╰─> To install Python packages system-wide, try 'pacman -S python-xyz', where xyz is the package you are trying to install.
  
     If you wish to install a non-Arch-packaged Python package, create a virtual environment using 'python -m venv path/to/venv'. Then use path/to/venv/bin/python and path/to/venv/bin/pip.
  
  ...

In essence, it strongly suggests creating a virtual environment, which is an unavoidable prerequisite no matter how you look at it.

So, with the help of ChatGPT, I built a virtual environment (similar to what you need to do before installing ComfyUI), following these steps:

• Enter the Blender Plugin Directory:

  cd ~/.config/blender/4.2/extensions/user_default    # This is the directory where the "pallaidium_generative_ai" plugin resides ('~' represents 'home/your_user_name/'). Blender custom plugins are all located here, and we can also place the virtual environment directory for the Pallaidium plugin in this location.

• Build the Virtual Environment:

  python -m venv pall_venv    # This "pall_venv" is the name of the virtual environment built for the Pallaidium plugin; you can change it to any name you prefer.

• Activate the Virtual Environment:

  source ~/.config/blender/4.2/extensions/user_default/pall_venv/bin/activate

• Start Blender from the Terminal:

  blender

Next, you can proceed with the following step:

• In the Generative AI add-on preferences, click the "Install Dependencies" button.

In the virtual environment directory ~/.config/blender/4.2/extensions/user_default/pall_venv/, the program will automatically install the necessary dependencies, and you can see the entire installation process in the terminal window.

After seeing a message similar to "installation completed," make sure to activate the virtual environment from the terminal and then start Blender from the terminal. This ensures that the Pallaidium plugin runs smoothly in an environment that satisfies all dependencies.

• Activate the Virtual Environment:

  source ~/.config/blender/4.2/extensions/user_default/pall_venv/bin/activate

• Start Blender from the Terminal:

  blender

Now, you can open the add-on UI in the Sequencer > Sidebar > Generative AI within the Video Editing workspace.

Just a reminder:

Every time you want to use Pallaidium in Blender, make sure to activate the virtual environment from the terminal and then start Blender from the terminal. This will ensure that the Pallaidium plugin runs smoothly in an environment that meets all dependencies.

you can combine the two commands into one line using &&, which ensures that Blender will only start if the virtual environment is successfully activated. Here's how it looks:

source ~/.config/blender/4.2/extensions/user_default/pall_venv/bin/activate && blender

This way, you can activate the virtual environment and start Blender in a single command.

Hi there! I’m new to Arch Linux and only understand simple English. Plus, I barely know anything about Python programming. The steps above were all taught to me by ChatGPT, and some of them might have been done correctly just by chance. If you have any questions or run into issues, I won't be much help—feel free to reach out to AI for assistance! Looking forward to sharing experiences with you. 😊
