errors in README.MD

[NotAlwaysTrue]

pip commands are actually don't work with Python 3.7, while Python 3.10 complete it without any error.

"Edit "model_dir"(line 152) in utils.py" should be replaced by "Edit "model_dir"(line 156) in utils.py" because it no longer correct.

Strongly advised to emphasize the importance to modify "config.json" because someone may NOT aware while reading README.MD because only 3 lines mentioned that.
