Update Intro YouTube Building Models tutorial — Softmax dim, super() style

[svekars]

Description

The Building Models with PyTorch tutorial has a deprecated nn.Softmax() call and uses outdated Python 2-style super() syntax.

Changes needed

Deprecated APIs

• nn.Softmax() → nn.Softmax(dim=1): Calling Softmax() without dim raises a UserWarning: "Implicit dimension choice for softmax has been deprecated." Specify the appropriate dimension explicitly.

Outdated patterns

• Python 2-style super() → super().__init__(): Update 3 classes:
  • super(TinyModel, self).__init__() → super().__init__()
  • super(LeNet, self).__init__() → super().__init__()
  • super(LSTMTagger, self).__init__() → super().__init__()

Files

• beginner_source/introyt/modelsyt_tutorial.py
