Proper installation steps

@Rongjiehuang I got this repo to work, but i had to correct some things. Hope it helps someone else.

Before starting the install, you should sudo apt install gfortran libopenblas-base. These are required but not specified.
Change environment.yaml to remove duplicates in scipy and numpy, and remove version requirements on scipy and numba (old vresions cause conflicts with numpy).
If you already installed CUDA yourself, remove the one installed with environment.yaml with pip uninstall nvidia_cublas_cu11 (or whatever version you have).
In modules/GenerSpeech/config/generspeech.yaml, change emotion_encoder_path to checkpoints/Emotion_encoder.pt
Add the Generspeech dir root to your sys.path, either by moving GenerSpeech.py to the GenerSpeech dir or adding these lines at the top of GenerSpeech (otherwise Python can't find the imports)
```
import sys, os
sys.path.insert(0, os.path.join(os.path.dirname(__file__), '..'))
```
Run mfa thirdparty download
In utils.hparams.py, lines 29 and 32 should remove help='location of the data corpus' becuase it's misleading. Line 41 needs to include remove=False.
Preprocessing fails at data_gen_utils line 299 if there is a word missing from mfa_dict.txt, because the TextGrid will skip the phones of the missing word. Actually, some common words are not in the dictionary like "her" (HH_ER1) and "processing" (P_R_AA1_S_EH0_S_IH0_NG). You have add them to the dictionary yourself. The correct way is to run mfa validate and append to mfa_dict.txt first (see this script),
Also you may want to use praatio as the standard TextGrid parser.
