Search help

Note: Searching from the top-level index page will search all documents. Searching from a specific document will search only that document.

Find an exact phrase: Wrap your search phrase in "" (double quotes) to only get results where the phrase is exactly matched. For example "PyTorch for the IPU" or "replicated tensor sharding"
Prefix query: Add an * (asterisk) at the end of any word to indicate a prefix query. This will return results containing all words with the specific prefix. For example tensor*

Fuzzy search: Use ~N (tilde followed by a number) at the end of any word for a fuzzy search. This will return results that are similar to the search word. N specifies the “edit distance” (fuzziness) of the match. For example Polibs~1
Words close to each other: ~N (tilde followed by a number) after a phrase (in quotes) returns results where the words are close to each other. N is the maximum number of positions allowed between matching words. For example "ipu version"~2
Logical operators. You can use the following logical operators in a search:
- + signifies AND operation
- | signifies OR operation
- - negates a single word or phrase (returns results without that word or phrase)
- () controls operator precedence

4. Setup

This chapter describes common setup steps that are needed to run applications in different ML frameworks.

4.1. Working with a Python virtual environment

It is good practice to work in a different Python virtual environment for each framework or even for each application. This section describes how you can create, activate and deactivate a Python virtual environment.

Create a Python virtual environment.

$ virtualenv -p python3 ~/graphcore/[venv_name]
where [venv_name] is the name of the virtual environment.

Activate the virtual environment so you can use it.

$ source ~/graphcore/[venv_name]/bin/activate
Now all subsequent installations will be local to that virtual environment.

Deactivate the virtual environment with:

$ deactivate

4.2. Running an application

You are now ready to run an application. Refer to the appropriate guide for the framework you are using:
