### 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.

* Install [PyTorch](https://pytorch.org/get-started/locally/).
> 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)

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 f
