Complete Guide to Using VoiceCraft 🔧

1. Installation Steps 🚀

To install VoiceCraft, the first step is to clone the code repository. Let’s take a look at the specific steps! 👩‍💻

1.1 Clone the Code Repository 🌐

First, let’s clone the VoiceCraft code repository from GitHub. Simply input the following command:

git clone git@github.com:jasonppy/VoiceCraft.git
cd VoiceCraft

• git clone: This Git command will copy the contents of the remote repository to your local machine, allowing you to play and develop in your own environment.
• cd VoiceCraft: Change to the cloned VoiceCraft project folder, so we can proceed with further operations from here!

1.2 Ensure Docker and NVIDIA Container Toolkit are Installed 🐋

Before proceeding, make sure your system has Docker and the NVIDIA Container Toolkit installed. VoiceCraft relies on Docker for managing its environment and dependencies! 📦

1.3 Build the Docker Image ⚙️

Next, we will create the Docker image by executing the following command:

docker build --tag "voicecraft" .

• docker build: This command creates a new Docker image based on the instructions in the Dockerfile.
• --tag "voicecraft": This gives the created image a catchy name (matching the project name) for later use.

1.4 Launch the Jupyter Container 🖥️

Now, we’ll start the Jupyter environment for further operations:

./start-jupyter.sh  # Linux
start-jupyter.bat   # Windows

• ./start-jupyter.sh or start-jupyter.bat: These scripts are used to start the Jupyter Notebook server on Linux and Windows, respectively, providing a user-friendly interface for viewing and interactive coding.

1.5 Access Through the URL in Logs 🌍

After starting the Jupyter server, we need to get the access link by checking the container’s logs:

docker logs jupyter

• docker logs jupyter: This command displays the logs of the Docker container named jupyter, usually listing a URL, which you can open in your browser to access Jupyter Notebook!

1.6 Optional: Access Container Shell 🐚

If you wish to delve deeper into operations, you can enter the container’s shell for access:

docker exec -it jupyter /bin/bash

• docker exec -it: This command allows you to execute new commands inside a running container.
• /bin/bash: Command to start a Bash shell in the command line, enabling direct interaction within the container.

1.7 Check GPU Availability 💻

Confirm the availability of the GPU within the Docker container by using the following command:

nvidia-smi

• nvidia-smi: This command displays the status of your NVIDIA GPU, ensuring that the drivers and CUDA are installed correctly for deep learning and other high-computation tasks!

1.8 Open inference_tts.ipynb 📄

Finally, open the inference_tts.ipynb file in your browser, and start experiencing the powerful capabilities of VoiceCraft! In this notebook, you’ll try out various audio generation tasks and enjoy its convenience and strength! 🎤

2. Detailed Code Explanation 📚

The following example code demonstrates how to create and train a basic linear regression model:

import numpy as np
import tensorflow as tf
import matplotlib.pyplot as plt

# Generate example data
x = np.random.rand(100).astype(np.float32)  # Generate 100 random numbers as input features
y = 2 * x + 1 + np.random.normal(0, 0.1, x.shape)  # Generate output with added random noise

# Linear model
model = tf.keras.Sequential([tf.keras.layers.Dense(1)])  # Build a simple linear model with a single output layer

# Compile model
model.compile(optimizer='sgd', loss='mean_squared_error')  # Use stochastic gradient descent optimizer and mean squared error as the loss function

# Train model
model.fit(x, y, epochs=100)  # Train the model for 100 epochs

# Predictions
y_pred = model.predict(x)  # Use the trained model to make predictions

# Visualize results
plt.scatter(x, y, color='blue')  # Plot the true output y values
plt.plot(x, y_pred, color='red')  # Plot the predicted outputs
plt.show()  # Display the graph

In this code example, we utilize several popular Python libraries to train a linear regression model:

• import: Import necessary libraries, including numpy (for efficient numerical computation), tensorflow (for machine learning and deep learning), and matplotlib (for graph plotting and data visualization).
• np.random.rand(100): Generate 100 random numbers between 0 and 1 to serve as our input features.
• np.random.normal(0, 0.1, x.shape): Add Gaussian noise with a mean of 0 and a standard deviation of 0.1 to the output values to make the data more realistic.
• tf.keras.Sequential(...): Create a sequential model, extremely simple, containing only one linear layer as output.
• model.compile(...): Compile the model, specifying the optimizer and loss function—using stochastic gradient descent for optimization and mean squared error for performance assessment!
• model.fit(...): Start training on data, enabling the model to learn how to predict the output from the input.
• model.predict(...): Use the trained model to make predictions, yielding the output.
• plt.scatter(...) and plt.plot(...): Draw the true data (in blue) and predicted results (in red), helping us visualize the model’s performance!

Give these features a try and embark on your VoiceCraft journey! 👏🎊
