Step 1: Create a Server Instance on Shape.Host

Before installing PyTorch, you’ll need a server to host your environment. Here’s how to set up a server instance on Shape.Host:

Log in to Shape.Host: Go to the Shape.Host website and log in to your account. Navigate to the Cloud VPS section.

Create a New Instance: Click on “Create” and choose the server type that fits your needs.

Pick a Data Center: Select a data center location close to your audience for better performance.

Choose a Plan: Pick a hosting plan that matches your project’s requirements and budget.

Set the OS: Choose Debian 12 as your operating system.

Launch the Server: Review your settings and click “Create Instance” Your server will be ready in a few minutes.

In Dashboard you will find your Instance IP.

---

Step 2: Connect to Your Server

Once your server is ready, you’ll need to connect to it using SSH. Here’s how:

• Linux/macOS: Open your terminal and type:

  ssh root@your_server_ip

Replace your_server_ip with your server’s IP address.

• Windows: Use an SSH client like PuTTY. Enter your server’s IP address, specify the port (usually 22), and click “Open.” Log in with your username and password.

---

Step 3: Update Your System

Before installing any software, it’s important to update your system to ensure all software is up to date. Run the following command:

apt update

---

Step 4: Install Python and Pip

PyTorch requires Python and Pip (Python’s package manager). Install them using the following commands:

apt install python3 -y
apt install python3-pip -y

---

Step 5: Install Virtualenv

To avoid conflicts between Python packages, we’ll use virtualenv to create an isolated environment for your PyTorch project. Install virtualenv with:

apt install virtualenv -y

---

Step 6: Create a Virtual Environment

Now, let’s create a virtual environment for your project. Run the following commands:

virtualenv my_project_env

This will create a folder named my_project_env containing the virtual environment.

---

Step 7: Activate the Virtual Environment

To start using the virtual environment, activate it with:

source my_project_env/bin/activate

You’ll notice that your terminal prompt changes, indicating that the virtual environment is active.

---

Step 8: Install PyTorch

With the virtual environment activated, you can now install PyTorch. Run the following command:

pip3 install torch torchvision torchaudio

This will install PyTorch along with its additional libraries, torchvision (for computer vision tasks) and torchaudio (for audio processing).

---

Step 9: Verify the Installation

To make sure PyTorch is installed correctly, open the Python interpreter:

python

Then, type the following commands in the Python shell:

import torch
print(torch.__version__)

If PyTorch is installed correctly, it will display the version number (e.g., 2.0.1). Exit the Python shell by typing:

exit()

---

Step 10: Deactivate the Virtual Environment

When you’re done working with PyTorch, you can deactivate the virtual environment by running:

deactivate

This will return you to the system’s default Python environment.
