problem in exp_manager

[freshpearYoon]

While following tutorial "Voice_Activity_Detection.ipynb", I confronted errors in
"exp_dir = exp_manager(trainer, config.get("exp_manager",None))"

I've changed nothing on the tutorial, and I am getting errrors.

WHen I first run the cell , I get
"---------------------------------------------------------------------------
FileNotFoundError Traceback (most recent call last)
Cell In[164], line 1
----> 1 exp_dir = exp_manager(trainer, config.get("exp_manager",None))

File ~/.conda/envs/nemo/lib/python3.10/site-packages/nemo/utils/exp_manager.py:510, in exp_manager(trainer, cfg)
507 _file.write(" ".join(sys.argv))
509 # Try to get git hash
--> 510 git_repo, git_hash = get_git_hash()
511 if git_repo:
512 with open(log_dir / 'git-info.log', 'w', encoding='utf-8') as _file:

-> 1863 raise child_exception_type(errno_num, err_msg, err_filename)
1864 raise child_exception_type(err_msg)

FileNotFoundError: [Errno 2] No such file or directory: 'git'"

and when I rerun the cell, I get
'LoggerMisconfigurationError: The pytorch lightning trainer that was passed to exp_manager contained a logger, and either create_tensorboard_logger: True or create_wandb_logger: False or create_mlflow_logger: Falseor create_dllogger_logger: False was set to True. These can only be used if trainer does not already have a logger. You can disable lighning's trainer from creating a logger by passing logger=False to its constructor'

I am using conda environment, which is recommended in README(python 3.10.12, cuda 11.8 etc)
