joddiy opened a new issue #634: cannot do matmul for high-dim tensors URL: https://github.com/apache/singa/issues/634 Hi, @dcslin , we ccannot do matmul for high-dim tensors: The error is: > F0324 05:47:19.174587 15611 tensor.cc:1413] Check failed: A.shape().size() == 2u (4 vs. 2) please use this test case: ```python3 x1 = np.random.randn(1, 12, 256, 64).astype(np.float32) x2 = np.random.randn(1, 12, 64, 256).astype(np.float32) x1 = tensor.from_numpy(x1) x1.to_device(gpu_dev) x2 = tensor.from_numpy(x2) x2.to_device(gpu_dev) y = autograd.Matmul()(x1, x2) print(tensor.to_numpy(y[0])) ```
