torch.FloatTensor(train_label).view(-1)

This line of code converts the train_label list into a one-dimensional tensor using the PyTorch library. The view() function is used to reshape the tensor into a one-dimensional shape. The parameter "-1" in the view function specifies that PyTorch should automatically calculate the size of the resulting tensor dimension based on the other dimensions and the total number of elements in the original tensor.
For example, if the original train_label tensor had a shape of (100, 1), the view(-1) function would reshape it into a tensor with a shape of (100).
Overall, this line of code is useful for converting a list of labels into a tensor that can be used for training a machine learning model using PyTorch.
