This means that it should work as is for your example: dist, idx = tf.nn.top_k (inputs, 64, sorted=False) In general you can imagine the Tensorflow version to work like the Pytorch version with hardcoded dim=-1, i.e. the last dimension. However it looks like you actually want the k ...
Webtorch.argsort(input, dim=- 1, descending=False, stable=False) → Tensor. Returns the indices that sort a tensor along a given dimension in ascending order by value. This is the second value returned by torch.sort (). See its documentation for the exact semantics of this method. If stable is True then the sorting routine becomes stable ...
