Error Loading Pre-trained Weights: Size Mismatch in DPTDepthModel when trying to run for first time.

[pablobiedma]

Hello everyone,
I am new to MiDaS and I am trying to get it to run for the first time.
I followed the instructions and added the downloaded weights to the weight folder.
Then I added 10 random images to the input folder.
After I run execution the following command: python run.py --model_type dpt_swin2_tiny_256 --input input --output output (also with model and weights for dpt_beit_large_512 and dpt_swin2_large_384) I get the following error message:

Essentially, I am encountering a size mismatch error when trying to load pre-trained weights into the DPTDepthModel. Despite ensuring that the model type and the pre-trained weights should be compatible, the error persists.

Do you know what my mistake is?
Any help is appreciated

Same problem here

@weijielyu I have managed to circumvent this issue by computing Depth of Field directly using this script, feel free to take a look: https://github.com/pablobiedma/DoF-with-MiDaSv3.1

Got it, thank you!

Your code does not load the model trained by MiDaSv3.1, but MiDaS v2.1

If the version of timm is too high, it will cause this problem. I replaced timm 0.9.7 with version 0.6.12 adapted to the project, and the problem disappeared

This solved the issue for me

For easy inference see #259

Works nice!

Thank you! I solved it through this way
