How I solved "Expected tensor for argument #1 ‘indices’ to have scalar type Long" error

Today I was trying to train my 2 layer LSTM on some long documentry extract and kept geting this irritating error
Expected tensor for argument #1 ‘indices’ to have scalar type Long; but got CPUFloatTensor instead (while checking arguments for embedding)

After many google searches and stackoverflow crawling, I figured out that the error was caused by the following line of code

dataset = TensorDataset(torch.Tensor(features), torch.Tensor(target))

Changed it to
dataset = TensorDataset(torch.tensor(features), torch.tensor(target))

and it fixed the issue


  1. Thanks a lot for sharing
    Having good health is what most people out there wants but can not achieve. some people takes buy ibogaine online AND buy weed online to get it.

  2. medical care is what many people lack in the interior areas of the world. people face a lot of health issues everyday without solution. buy magic mushroom, Buy weed online, Buy heroin online
