16.12.2018 · That's because in PyTorch>=0.5, the index of 0-dim tensor is invalid. The master branch is designed for PyTorch 0.4.1, loss_val.data[0] works well. Try to change

Torchserve need to return a list of inference results (check here). In your case you are returning a torch.Tensor so it's invalid.

torch.ByteTensor. /. 1. Sometimes referred to as binary16: uses 1 sign, 5 exponent, and 10 significand bits. Useful when precision is important at the expense of range. 2. Sometimes referred to as Brain Floating Point: uses 1 sign, 8 exponent, and 7 significand bits. Useful when range is important, since it has the same number of exponent bits ...

比如，torch.FloatTensor.abs_()会在原地计算绝对值，并返回改变后的tensor，而tensor.FloatTensor.abs()将会在一个新的tensor中计算结果。 class torch.Tensor class torch.Tensor(*sizes) class torch.Tensor(size) class torch.Tensor(sequence) class torch.Tensor(ndarray) class torch.Tensor(tensor) class torch.Tensor(storage)

Dec 16, 2018 · That's because in PyTorch>=0.5, the index of 0-dim tensor is invalid. The master branch is designed for PyTorch 0.4.1, loss_val.data [0] works well. Try to change total_loss += loss_val. data [ 0 ] loss_values = [ v. data [ 0] for v in losses] to total_loss += loss_val. data loss_values = [ v. data for v in losses] might fix the problem.

for feature in features: print("feature.shape = {}".format(feature.shape)) Output: feature.shape = torch.Size([4, 2048, 2, 4]) feature.shape = torch.

04.12.2018 · So cpu_tensor.to(device) or torch.Tensor([1., 2.], device='cuda') will actually return a tensor of type torch.cuda.FloatTensor. In which scenario is torch.cuda.Tensor() necessary? When you want to use GPU acceleration (which is much faster in most cases) for your program, you need to use torch.cuda.Tensor , but you have to make sure that ALL tensors you are using are CUDA …

A tensor can be constructed from a Python list or sequence using the torch.tensor () constructor: torch.tensor () always copies data. If you have a Tensor data and just want to change its requires_grad flag, use requires_grad_ () or detach () to avoid a copy.

torch.tensor() expects a sequence or array_like to create a tensor whereas torch.Tensor() class can create a tensor with just shape ...
