Description

• Details regarding the bug
  • Zero Padding not allowed by Convolve2_nn
• Did you build ArrayFire yourself or did you use the official installers
  • Official Installers
• Which backend is experiencing this issue? (CPU, CUDA, OpenCL)
  • all of them
• Do you have a workaround?
  • No
• Can the bug be reproduced reliably on your system?
  • Yes
• A clear and concise description of what you expected to happen.
  • My understanding was this was resolved in fix zero padding in convolve2NN arrayfire#2820
• Run your executable with AF_TRACE=all and AF_PRINT_ERRORS=1 environment
  variables set.
• Screenshot or terminal output of the results from above run

Reproducible Code and/or Steps

#[test]
    fn mnist__convolutional_neural_net__learns_mnist_fail() {
        let signal = randu::<f32>(dim4!(8, 8, 3, 1));

        let quadrant1 = Array::new(&vec![1f32, 0.0, 0.0, 0.0], dim4![2, 2, 1, 1]);

        let q1 = convolve2_nn(
            &signal,
            &quadrant1,
            dim4!(2, 2, 1, 1),
            dim4!(0, 0, 1, 1),
            dim4!(1, 1, 1, 1),
        );

        af_print!("q1", q1);
    }
