The size of tensor a (288) must match the size of tensor b (192) at non-singleton dimension 3

[roblaughter]

I'm getting the following intermittently after a few runs. Adjusting the settings in the Automatic CFG node lets it run a few more times, and then we come back to this, which makes me feel like it's a caching thing.

Ideas on how to troubleshoot?

Error occurred when executing SamplerCustom:

The size of tensor a (288) must match the size of tensor b (192) at non-singleton dimension 3

Here's my implementation.

[Extraltodeus]

Well for starters the warp drive and the other one are made to be used independently. I should make this more clear. Sorry.
Then it seems to relates to the size of the conditioning so the apparent randomness of the error relates to the size of your prompts. As for now I'm not sure what causes it.

When you get the error, can you try to see which other node is incompatible? My best guess would be the token downsampling node.

[roblaughter]

The prompt size doesn't seem to matter. It's happened with like 10 token prompts, and with huge concatenated conditionings.

It's hard to pinpoint an incompatible node because 1.) it works most of the time, and 2.) any change in the model pipeline fixes it, even if it's just incrementing some value in any one of the nodes between the model load and the sampler.

[roblaughter]

Removing the warp drive node seems to have resolved the problem for now.
