Flip a Tensor

Description

Hi, thanks for contributions.

How can i flip a tensor like torch.flip? There is no implementation of flip function in Playtorch docs

Another solution i thought is to make a new tensor and assign reversed values using for loop such as the tensor[::, ::-1] . However, i got a result Cannot assign to property ~ My code and the corresponding error are as follows.

CODE: e.g., (.js file)

  let tempTensor = torch.zeros(1);
  console.log('temp value', tempTensor.data());
  console.log('temp shape', tempTensor.shape);
  tempTensor[0].data = 5; //or tempTensor[0]
  console.log('result', tempTensor.data());

ERROR: e.g.,

 LOG  temp value [0]
 LOG  temp shape [1]
 WARN  Possible Unhandled Promise Rejection (id: 10):
Error: Exception in HostObject::set for prop 'data': TypeError: Cannot assign to property 'data' on HostObject with default setter

How can i solve this problem? Many thanks for your help :)

@raedle, Thank you so much 😄 My app gets a fliped image, so i have to flip image before our models infer this image. In detail, my app will use tensor.permute ([2,1,0]) and flip, because it receives images rotated 90 degrees. I will report back if I have any questions or if this problem is solved.

Fantastic to hear, @nh9k! I’ll close the issue, then
