QuickStart example for pruning is not working properly !!

[hamdy-cryptic]

Describe the bug: QuickStart Example provides Error at model SpeedUp. AttributeError: 'NoneType' object has no attribute 'startswith'. I tried running the pruning example quick start code and all worked fine until the section of model speedup.

Environment:

• NNI version: 3
• Training service (local|remote|pai|aml|etc):
• Python version: 3.10
• PyTorch version: 2.2
• Cpu or cuda version: CPU

Reproduce the problem

• Code|Example: from nni.compression.speedup import ModelSpeedup

ModelSpeedup(model, torch.rand(3, 1, 28, 28).to(device), masks).speedup_model()

• How to reproduce: AttributeError Traceback (most recent call last) in <cell line: 7>() 5 from nni.compression.speedup import ModelSpeedup 6 ----> 7 ModelSpeedup(model, torch.rand(3, 1, 28, 28).to(device), masks).speedup_model()

using pytorch version 2.1. it works for me

[yating-zh]

!pip install torch torchvision==0.16.0 torchaudio==2.1.0 pytorch-cuda==12.1 Downgrade the Python version to 2.1.0; it works.
