This article introduces the "Torch7 installation and configuration tutorial under Ubuntu" related knowledge, in the actual case operation process, many people will encounter such a dilemma, then let the editor lead you to learn how to deal with these situations! I hope you can read it carefully and be able to achieve something!

Why choose Torch?

The goal of Torch is to build scientific algorithms with maximum flexibility and speed, and the process is very simple. Torch has an ecosystem of large community driver packages involving machine learning, computer vision, signal processing, parallel processing, image, video, audio and network, and is based on the Lua community.

At the core of Torch are popular neural networks and optimization libraries, which are easy to use and have the greatest flexibility in implementing complex neural network topologies. You can build any neural network graph and parallelize it effectively on CPUs and GPUs.

Before installation, make sure to install the git tool under your Ubuntu, open the terminal through Ctrl+Alt+T, enter git under the terminal, and add terminal output

Then your system does not have git installed. Type sudo apt install git under the terminal to install it, as shown in the following figure.

After confirming the successful installation of the git tool, you can begin to install Torch7!

Step one:

Get the dependency packages necessary to install LuaJIT (the interpreter for Lua written in C) and Torch. The code is as follows: git clone https://github.com/torch/distro.git ~ / torch-- recursive as shown in the following figure.

Step 2:

By default, the dependency package will be downloaded under the torch file under the current path, go to the torch folder, open and execute the command in install-deps (this command may take a long time, don't worry). The code is as follows:

Step 3:

Execute the install.sh file, as shown in the following figure.

Terminal prompt:

Do you want to automatically prepend the Torch install locationto PATH and LD_LIBRARY_PATH in your / home/guodongwei/.bashrc? (yes/no)

Enter: yes as shown in the figure above.

Step 4:

Manually add the path to the PATH variable:

And then

Step 5:

Check whether the installation is successful. Enter the th command in the terminal, if the following figure appears, it indicates that the installation is successful.

Now that Torch7 has been successfully installed, you can use it for your own machine learning tasks. The following will be a more detailed analysis of the introduction to Torch7de.

This is the end of the tutorial on the installation and configuration of Torch7 under Ubuntu. Thank you for reading. If you want to know more about the industry, you can follow the website, the editor will output more high-quality practical articles for you!
