1.cmap_up.0:0:DECONVOLUTION:GPU:kernel weights has count 2097152 but 4194304 was expected

[Raven19888]

I ran into the following problem when converting densenet121_baseline_att_256x256_B_epoch_160.pth and also resnet18_baseline_att_224x224_A_epoch_249.pth into a trt model, which appears to be due to a mismatch between the model weight and the model definition. Does anyone know how to fix it?

Hi. I meet the same problem when converting resnet18_baseline_att_224x224_A_epoch_249.pth to a trt model. The error is "[TRT] [E] Error Code: 3: 1.cmap_up.0:0:DECONVOLUTION:GPU: kernel weights has count 2097152 but 4194304 was expected". Have you fixed it?

Hi everyone,

I'm experiencing this exact same issue when trying to convert my model to TensorRT (TRT), even though I'm following the steps outlined in the live_demo.ipynb notebook.

The specific error I'm consistently getting is:

[07/22/2025-13:05:33] [TRT] [E] 3: 1.cmap_up.0:0:DECONVOLUTION:GPU:kernel weights has count 2097152 but 4194304 was expected
[07/22/2025-13:05:33] [TRT] [E] 4: 1.cmap_up.0:0:DECONVOLUTION:GPU: count of 2097152 weights in kernel, but kernel dimensions (4,4) with 512 input channels, 512 output channels and 1 groups were specified. Expected Weights count is 512 * 4*4 * 512 / 1 = 4194304

This problem is currently preventing me from moving forward with model optimization and deployment.

Has anyone found a reliable solution or even a workaround for this "kernel weights count mismatch" error? Any insights or suggestions would be greatly appreciated.

Thanks in advance!
