TypeError: 'type' object is not subscriptable

[zakinp]

An error called "TypeError: 'type' object is not subscriptable" occurs when using 'train_network.py' to finetune model.

The whole message is:

It seems to be related to the 'networks.lora' module. How to fix this ? Btw, the '--network_module' cannot be set as 'None', otherwise an another error will appear:

The error seems to be related to type hints feature of Python.

->list[LoRAModule]:

This notation seems to be supported from Python 3.9. This repo is tested on Python 3.10, but you seem to use Python 3.8. Please update Python to 3.10.x.

If it is difficult, please remove ->list[LoRAModule]. However, another error might occur, so I recommend to use Python 3.10.

thanks, I'll try it later.

I found that this error is caused by python version, which should be updated to 3.10.x. This issue can be closed.
