Issue using custom network (Converting tensor to float)

Sorry, this may be a basic question, but:

I trained a network that takes a standardized float tensor as input. When I try to run the network, I get

E/StyleTransfer: Error performing StyleTransfer: [enforce fail at tensor.h:507] IsType<T>(). Tensor type mismatch, caller expects elements to be float while tensor contains unsigned char Error from operator: 
    input: "0" output: "49" name: "" type: "PadImage" arg { name: "pads" ints: 3 ints: 3 ints: 3 ints: 3 } arg { name: "mode" s: "reflect" } device_option { device_type: 0 cuda_gpu_id: 0 }
    ** while accessing input: 0

As far as I can tell, this means that the tensor I'm passing into the network via Predictors::run is an unsigned char rather than float tensor. I was hoping to convert my tensor into a float tensor and standardize it in preprocessImage in native-lib.cpp, but I can't for the life of me figure out how to convert the input tensor into a float tensor. Anyone have any suggestions?

The app produces incorrect output image

Hi,

I was able to build and run the app but it seems the app produce incorrect output. I couldn't see the "night" effect on the output as shown in the sample image. Instead, the output image look just messed up. Any help here would be appreciated.

I wonder if we have to convert the format of the output_tensor? The input image_tensor is converted to format by preprocessImage() function before the input image is transformed. What is the format of the output image holding in <output_tensor>?

On the other hand, in the displayImage() function in StyleTransfer.javar, it try to create a bitmap from the ouput pixels as <Bitmap.Config.ARGB_8888> ==> it expects the output of transformImageWithCaffe2() in ARGB_8888.

Original Image:

Transformed Image with Night_b

Thanks,

How was the StyleTransfer model trained for Caffe2?

I found the model is different from what was proposed form the original StyleTransfer paper:
https://arxiv.org/abs/1508.06576

The original model has been implemented with Caffe:
https://github.com/fzliu/style-transfer

May I know how did you train these Caffe2 models? Did you transfer the learning of the original paper model to the new Caffe2 model here?

won't build

Tried to build on Windows and Ubuntu 18.04. Same linker errors in both cases:
