 * For `MatMul` and `Gemm`, the matrix dimensions must be divisible by 2, or the output matrix must be of size (1, N). Matrix 
   multiplication only supports floats, not integers (this is a WebGPU/WGSL limitation).
 
+* The Slice operator can only be computed for axes of length one. (i.e., there must always be exactly one axis.)

 ### Shape inference
 
 WONNX needs to know the shape of input and output tensors for each operation in order to generate shader code for executing
