 * 安装 [ffmpeg](https://ffmpeg.org/download.html#get-packages)。
 * 运行`pip install -r requirements.txt` 来安装剩余的必要包。
+> 这里的环境建议使用 `Repo Tag 0.0.1` `Pytorch1.9.0 with Torchvision0.10.0 and cudatoolkit10.2` `requirements.txt` `webrtcvad-wheels` 因为 `requiremants.txt` 是在几个月前导出的，所以不适配新版本

+>
+  >  如需使用M1芯片训练，因`demo_toolbox.py`依赖的`PyQt5`不支持M1，则应按需修改代码，或者尝试使用`web.py`。
+
+* 安装`PyQt5`，参考[这个链接](https://stackoverflow.com/a/68038451/20455983)
+  * 用Rosetta打开Terminal，参考[这个链接](https://dev.to/courier/tips-and-tricks-to-setup-your-apple-m1-for-development-547g)

+  > 这里两个文件直接`pip install`的时候找不到wheel，尝试从c里build时找不到`Python.h`报错
+  * 安装`pyworld`
+    * `brew install python` 通过brew安装python时会自动安装`Python.h`
+    * `export CPLUS_INCLUDE_PATH=/opt/homebrew/Frameworks/Python.framework/Headers` 对于M1，brew安装`Python.h`到上述路径。把路径添加到环境变量里

+```
+#### 2.1.2 数据批量解压
+```shell
+# 该指令为解压当前目录下的所有压缩文件 
+
+for gz in *.gz; do tar -zxvf $gz; done
+```
+### 2.2 encoder模型训练
+#### 2.2.1 数据预处理：
+需要先在`pre.py `头部加入：
+```python
+import torch
+torch.multiprocessing.set_start_method('spawn', force=True)
+```
+使用以下指令对数据预处理：
+```shell
+python pre.py <datasets_root> \
+           -d <datasets_name> 
+```
+其中`<datasets_root>`为原数据集路径，`<datasets_name>` 为数据集名称。
+
+支持 `librispeech_other`，`voxceleb1`，`aidatatang_200zh`，使用逗号分割处理多数据集。
+
+### 2.2.2 encoder模型训练：
+超参数文件路径：`models/encoder/hparams.py`
+```shell
+python encoder_train.py <name> \
+                        <datasets_root>/SV2TTS/encoder
+```
+其中 `<name>` 是训练产生文件的名称，可自行修改。
+
+其中 `<datasets_root>` 是经过 `Step 2.1.1` 处理过后的数据集路径。
+#### 2.2.3 开启encoder模型训练数据可视化（可选）
+```shell
+visdom
+```
+
+### 2.3 synthesizer模型训练
+#### 2.3.1 数据预处理：
+```shell
+python pre.py    <datasets_root> \
+              -d <datasets_name> \
+              -o <datasets_path> \
+              -n <number>
+```
+`<datasets_root>` 为原数据集路径，当你的`aidatatang_200zh`路径为`/data/aidatatang_200zh/corpus/train`时，`<datasets_root>` 为 `/data/`。
+ 
+`<datasets_name>` 为数据集名称。
+ 
+`<datasets_path>` 为数据集处理后的保存路径。
+
+`<number>` 为数据集处理时进程数，根据CPU情况调整大小。
+
+#### 2.3.2 新增数据预处理：
+```shell
+python pre.py    <datasets_root> \
+              -d <datasets_name> \
+              -o <datasets_path> \
+              -n <number> \
+              -s
+```
+当新增数据集时，应加 `-s` 选择数据拼接，不加则为覆盖。
+#### 2.3.3 synthesizer模型训练：
+超参数文件路径：`models/synthesizer/hparams.py`，需将`MockingBird/control/cli/synthesizer_train.py`移成`MockingBird/synthesizer_train.py`结构。
+```shell
+python synthesizer_train.py <name> <datasets_path> \
+                                -m <out_dir>
+```
+其中 `<name>` 是训练产生文件的名称，可自行修改。
+
+其中 `<datasets_path>` 是经过 `Step 2.2.1` 处理过后的数据集路径。
+
+其中 `<out_dir> `为训练时所有数据的保存路径。
+
+### 2.4 vocoder模型训练
+vocoder模型对生成效果影响不大，已预置3款。
+#### 2.4.1 数据预处理
+```shell
+python vocoder_preprocess.py <datasets_root> \
+                          -m <synthesizer_model_path>
+```
+
+其中`<datasets_root>`为你数据集路径。
+
+其中 `<synthesizer_model_path>`为synthesizer模型地址。
+
+#### 2.4.2 wavernn声码器训练:
+```
+python vocoder_train.py <name> <datasets_root>
+```
+#### 2.4.3 hifigan声码器训练:
+```
+python vocoder_train.py <name> <datasets_root> hifigan
+```
+#### 2.4.4 fregan声码器训练:
+```
+python vocoder_train.py <name> <datasets_root> \
+                        --config config.json fregan
+```
+将GAN声码器的训练切换为多GPU模式：修改`GAN`文件夹下`.json`文件中的`num_gpus`参数。

-* Major upgrade on GUI/Client and unifying web and toolbox
-[X] Init framework `./mkgui` and [tech design](https://vaj2fgg8yn.feishu.cn/docs/doccnvotLWylBub8VJIjKzoEaee)
-[X] Add demo part of Voice Cloning and Conversion
-[X] Add preprocessing and training for Voice Conversion
-[ ] Add preprocessing and training for Encoder/Synthesizer/Vocoder
-* Major upgrade on model backend based on ESPnet2(not yet started)

 ## Quick Start
 
 ### 1. Install Requirements
+#### 1.1 General Setup
 > Follow the original repo to test if you got all environment ready.
 **Python 3.7 or higher ** is needed to run the toolbox.
 
@@ -36,9 +31,76 @@
 > If you get an `ERROR: Could not find a version that satisfies the requirement torch==1.9.0+cu102 (from versions: 0.1.2, 0.1.2.post1, 0.1.2.post2 )` This error is probably due to a low version of python, try using 3.9 and it will install successfully
 * Install [ffmpeg](https://ffmpeg.org/download.html#get-packages).
 * Run `pip install -r requirements.txt` to install the remaining necessary packages.
+> The recommended environment here is `Repo Tag 0.0.1` `Pytorch1.9.0 with Torchvision0.10.0 and cudatoolkit10.2` `requirements.txt` `webrtcvad-wheels` because `requirements. txt` was exported a few months ago, so it doesn't work with newer versions
 * Install webrtcvad `pip install webrtcvad-wheels`(If you need)
-> Note that we are using the pretrained encoder/vocoder but synthesizer since the original model is incompatible with the Chinese symbols. It means the demo_cli is not working at this moment.
+
+or
+- install dependencies with `conda` or `mamba`
+
+  ```conda env create -n env_name -f env.yml```
+
+  ```mamba env create -n env_name -f env.yml```
+
+  will create a virtual environment where necessary dependencies are installed. Switch to the new environment by `conda activate env_name` and enjoy it.
+  > env.yml only includes the necessary dependencies to run the project，temporarily without monotonic-align. You can check the official website to install the GPU version of pytorch.
+
+#### 1.2 Setup with a M1 Mac
+> The following steps are a workaround to directly use the original `demo_toolbox.py`without the changing of codes.
+>
+  >  Since the major issue comes with the PyQt5 packages used in `demo_toolbox.py` not compatible with M1 chips, were one to attempt on training models with the M1 chip, either that person can forgo `demo_toolbox.py`, or one can try the `web.py` in the project.
+
+##### 1.2.1 Install `PyQt5`, with [ref](https://stackoverflow.com/a/68038451/20455983) here.
+  * Create and open a Rosetta Terminal, with [ref](https://dev.to/courier/tips-and-tricks-to-setup-your-apple-m1-for-development-547g) here.
+  * Use system Python to create a virtual environment for the project
+    ```
+    /usr/bin/python3 -m venv /PathToMockingBird/venv
+    source /PathToMockingBird/venv/bin/activate
+    ```
+  * Upgrade pip and install `PyQt5`
+    ```
+    pip install --upgrade pip
+    pip install pyqt5
+    ```
+##### 1.2.2 Install `pyworld` and `ctc-segmentation`
+
+> Both packages seem to be unique to this project and are not seen in the original [Real-Time Voice Cloning](https://github.com/CorentinJ/Real-Time-Voice-Cloning) project. When installing with `pip install`, both packages lack wheels so the program tries to directly compile from c code and could not find `Python.h`.
+
+  * Install `pyworld`
+      * `brew install python` `Python.h` can come with Python installed by brew
+      * `export CPLUS_INCLUDE_PATH=/opt/homebrew/Frameworks/Python.framework/Headers` The filepath of brew-installed `Python.h` is unique to M1 MacOS and listed above. One needs to manually add the path to the environment variables.
+      * `pip install pyworld` that should do.
+
+
+  * Install`ctc-segmentation`
+    > Same method does not apply to `ctc-segmentation`, and one needs to compile it from the source code on [github](https://github.com/lumaku/ctc-segmentation).
+    * `git clone https://github.com/lumaku/ctc-segmentation.git`
+    * `cd ctc-segmentation`
+    * `source /PathToMockingBird/venv/bin/activate` If the virtual environment hasn't been deployed, activate it.
+    * `cythonize -3 ctc_segmentation/ctc_segmentation_dyn.pyx`
+    * `/usr/bin/arch -x86_64 python setup.py build` Build with x86 architecture.
+    * `/usr/bin/arch -x86_64 python setup.py install --optimize=1 --skip-build`Install with x86 architecture.
+
+##### 1.2.3 Other dependencies
+  * `/usr/bin/arch -x86_64 pip install torch torchvision torchaudio` Pip installing `PyTorch` as an example, articulate that it's installed with x86 architecture
+  * `pip install ffmpeg`  Install ffmpeg
+  * `pip install -r requirements.txt` Install other requirements.
+
+##### 1.2.4 Run the Inference Time (with Toolbox)
+  > To run the project on x86 architecture. [ref](https://youtrack.jetbrains.com/issue/PY-46290/Allow-running-Python-under-Rosetta-2-in-PyCharm-for-Apple-Silicon).
+  * `vim /PathToMockingBird/venv/bin/pythonM1` Create an executable file `pythonM1` to condition python interpreter at `/PathToMockingBird/venv/bin`.
+  * Write in the following content:
+    ```
+    #!/usr/bin/env zsh
+    mydir=${0:a:h}
+    /usr/bin/arch -x86_64 $mydir/python "$@"
+    ```
+  * `chmod +x pythonM1` Set the file as executable.
+  * If using PyCharm IDE, configure project interpreter to `pythonM1`([steps here](https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#add-existing-interpreter)), if using command line python, run `/PathToMockingBird/venv/bin/pythonM1 demo_toolbox.py`
+

 ### 2. Prepare your models
+> Note that we are using the pretrained encoder/vocoder but not synthesizer, since the original model is incompatible with the Chinese symbols. It means the demo_cli is not working at this moment, so additional synthesizer models are required.
