Rencontrant le même problème, a-t-il été résolu ?

No, personally I've had this problem of renderings not being displayed on subgraphs since the 3.50, 3.51 updates.

Same issue here. I just updated the front end, which I had hesitated on for a while. I'm not entirely sure which version I was on previously unfortunately. But same thing. I tend to rely on TAESD preview in the ksampler to decide if I want to continue the pass, but it no longer shows anything. Tried "auto" and the other options to see if that made any difference. It did not.

I solved it by uninstalling Video Helper Suite (VHS) and then going back in and reinstalling it.

This seemed to do the trick. Thanks. For whatever reason the update wasn't working.

Got this problem again.

For some reason now it appends some "light" into the path: Warning: TAESD previews enabled, but could not find models/vae_approx/lighttaew2_1

while my taew2_1.safetensors and taew2_1.pth both are located in just models/vae_approx

anyone here got this problem again?

I had to add the following flag starting comfyui: --preview-method taesd And it worked
