Bugs in FinRL-Tutorials

The bug is in [FinRL-Tutorial 1-Introduction Stock_NeurIPS2018_1_Data.ipynb
](https://github.com/AI4Finance-Foundation/FinRL-Tutorials/blob/master/1-Introduction/Stock_NeurIPS2018/Stock_NeurIPS2018_1_Data.ipynb)
## Environment
`python`: 3.7.16; `swig`: 4.2.1; `wrds`: 3.1.6; `pyportfolioopt`: 0.3.2

After I ran cell 1, cell 2 requires me to download more package including `yfinance`, `finrl`, `gymnasium`, `stable-baselines3[extra]`, `exchange-calendars`

After I pip install all those packages, I got this error:

```bash
