finetune/requirements.txt dependancy issues

[komaksym]

I was trying to run some finetuning, but was getting a few errors traced to dependancies in requirements.txt.
Some of these are:

1. ImportError: cannot import name 'BUFSIZE' from 'numpy' (/root/finetune/lib/python3.10/site-packages/numpy/__init__.py)
2. AttributeError: 'DeepSpeedCPUAdam' object has no attribute 'ds_opt_adam'
3. pydantic_core._pydantic_core.ValidationError: 1 validation error for DeepSpeedZeroConfig

I was able to figure these out by changing a few versions / specifications of some dependancies, I will open a PR soon
