Creating and Activating a Virtual Environment

1. Create a Virtual Environment:
   Open your terminal and execute the following command to create a virtual environment. Replace myenv with your preferred environment name.

   python3 -m venv ~/myenv
   

2. Activate the Virtual Environment:
   Activate the created virtual environment using the command below. The activation command differs based on the operating system:

   • On macOS or Linux:

     source ~/myenv/bin/activate
     

   Once activated, your terminal prompt will change to indicate that you are in a virtual environment.

   python3 -m venv ~/myenv
   source ~/myenv/bin/activate
   (myenv) ➜ pip3 install torch
   

3. Deactivate the Virtual Environment:

   • On macOS or Linux:

     deactivate
     

4. Installing PyTorch

With the virtual environment activated, you can install PyTorch using pip:

(myenv) ➜  ~ pip3 install torch

This command will download and install PyTorch and its dependencies into your virtual environment.

5. Verifying the Installation

After the installation is complete, you can verify the installation of PyTorch by executing:

(myenv) python -c "import torch; print(torch.__version__)"

If the installation was successful, this command will print the installed version of PyTorch.

6. Locate the Installed Packages

To find out where Python packages are installed, use the site module:

(myenv) ➜  python3 -m site

This command will list several directories, including where the global site-packages are located.

7. Find the Location of a Specific Package

To find out where a specific package is installed, use pip show:

(myenv) ➜ ~ pip3 show [package-name]

(myenv) ➜  ~ pip3 show torch
