I am Trying to implement the LaMa: Resolution-robust Large Mask Inpainting with Fourier Convolutions model on MNN, this runs properly on CPU backend but when selected METAL backend the output consists of all zeros. The original model is in pytorch so I used the ONNX implementation of it via this export notebook, both fp16 and fp32 versions of the model give 0 output on METAL

MNN Convert Command used:

./MNNConvert -f ONNX --modelFile lama_fp32.onnx --MNNModel lamafp16.mnn --fp16 --bizCode MNN --debug

Converted from a different machine(Linux)

GPU(Metal) Output:

Code Snippet

P.s any other model runs fine on GPU(Metal), the problem is with this one

Any Help Would be Appreciated :)
