This error occurs when only the ComfyUI-Manager is installed

Make sure up to date. ComfyUI.
I have confirmed that the issue does not occur in my current updated environment.

[traugdor]

I am using the latest version:

ComfyUI master* $ git status
On branch master
Your branch is up to date with 'origin/master'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)

        AddPromptToImage.ps1
        comfyui.log
        comfyui.prev.log
        comfyui.prev2.log
        config.json
        pysssss-workflows/
        qmSmartNodesConfig.json
        run.bat
        run.ps1

nothing added to commit but untracked files present (use "git add" to track)

I also updated the ComfyUI-Manager as well and got the same issue.

TypeError: Cannot handle this data type: (1, 1, 3), <f4

I am using a Radeon 6600XT, I don't know if that makes any difference...

Execute pip freeze.
What is displayed?

You should check this issue thread.

Execute pip freeze. What is displayed?

Since you asked, but looking at that other thread I see it's no longer relevant, but do you still need this information?

No, that's not necessary. You can just keep checking until a solution is posted in that thread.

[traugdor]

A solution was posted, and I have a pending PR on the main ComfyUI repo for it.
