ValueError: ExperimentConfig: type of experiment_name (None) is not typing.Optional[str]

[hayatejp]

Describe the issue:
Hello,Following the document and guide of NNI in a new computer, I tried to start the HPO Quickstart with Pytorch Document Link,I followed the steps and then at the step of "experiment.run(8080)",it occured the error"ValueErr

or: ExperimentConfig: type of experiment_name (None) is not typing.Optional[str]"
The full error output is as followed:

I have tried it in varites of running envrionment but the error occured as well.So I am not sure that there is some essential step that not mentioned in the doc , or some issues of NNI.

I also tried the method with nnictl Document Link,When I used the demand " nnictl create --config config.yml --port 8080"(Both for my config files and the nni example config),it could occur the error that :

Even I tried the other trial project or the command "nnictl hello",these also happened.But the command like "nnictl --version" runs normally.

Environment:

• NNI version:2.10（I also tried the old Version such as 2.7,2.9）
• Training service (local|remote|pai|aml|etc):Local
• Client OS:Windows 10（native mode and WSL2 of Ubuntu）
• Server OS (for remote mode only):None
• Python version:3.9(I also tried in 3.7,which also occured)
• PyTorch/TensorFlow version:1.13
• Is conda/virtualenv/venv used?:Yes,Conda
• Is running in Docker?:No

Configuration:

• Experiment config (remember to remove secrets!):
  from nni.experiment import Experiment
  experiment = Experiment('local')

search_space = {
#'features': {'_type': 'choice', '_value': [128, 256, 512, 1024]},
'lr': {'_type': 'loguniform', '_value': [1e-4, 1e-3]},
#'momentum': {'_type': 'uniform', '_value': [0, 1]},
'num_epochs': {'_type': 'choice', '_value': [3, 4, 5]},
'eps': {'_type': 'uniform', '_value': [1e-8, 1e-7]},

}

experiment.config.trial_command = 'python model.py'
experiment.config.trial_code_directory = '.'
experiment.config.tuner.name = 'TPE'
experiment.config.tuner.class_args['optimize_mode'] = 'maximize'
experiment.config.max_trial_number = 10
experiment.config.trial_concurrency = 2
max_experiment_duration = '1h'
experiment.run(8080)

• Search space:Mentioned above

Log message:

• nnimanager.log:
• dispatcher.log:
• nnictl stdout and stderr:

How to reproduce it?:
Following the two Documents mentions above in the new computer, then these would be reproduced.

Hello, pip install "typeguard<3" may solve this problem.
Reference: #5457

Thank you beta1scat,It works

I met this error, too. Why does this happen?

Hello,you can try "pip install typeguard==2.13"
