Sometimes it makes sense to execute two or more commands in parallel. A group
|
||||
of commands executed at once is known as a multiprocessing group; a multiprocessing group
|
||||
is defined by indenting the commands it contains. You are responsible for making sure that no
|
||||
of commands executed in parallel is defined using the `parallel` keyword mapping to
|
||||
the commands specified as a list. You are responsible for making sure that no
|
||||
deadlocks, race conditions or other issues can arise from the parallel execution.

|
|||
| `env` | A dictionary of variables, mapped to the names of environment variables that will be read in when running the project. For example, `${env.name}` will use the value of the environment variable defined as `name`. |
|
||||
| `directories` | An optional list of [directories](#project-files) that should be created in the project for assets, training outputs, metrics etc. spaCy will make sure that these directories always exist. |
|
||||
| `assets` | A list of assets that can be fetched with the [`project assets`](/api/cli#project-assets) command. `url` defines a URL or local path, `dest` is the destination file relative to the project directory, and an optional `checksum` ensures that an error is raised if the file's checksum doesn't match. Instead of `url`, you can also provide a `git` block with the keys `repo`, `branch` and `path`, to download from a Git repo. |
|
||||
| `workflows` | A dictionary of workflow names, mapped to a list of command names, to execute in order. Nested lists represent groups of commands to execute concurrently. Workflows can be run with the [`project run`](/api/cli#project-run) command. |
|
||||
| `workflows` | A dictionary of workflow names, mapped to a list of command names, to execute in order. The `parallel` keyword mapping to a list of command names specifies parallel execution. Workflows can be run with the [`project run`](/api/cli#project-run) command. |
|
||||
| `commands` | A list of named commands. A command can define an optional help message (shown in the CLI when the user adds `--help`) and the `script`, a list of commands to run. The `deps` and `outputs` let you define the created file the command depends on and produces, respectively. This lets spaCy determine whether a command needs to be re-run because its dependencies or outputs changed. Commands can be run as part of a workflow, or separately with the [`project run`](/api/cli#project-run) command. |
|
||||
| `spacy_version` | Optional spaCy version range like `>=3.0.0,<3.1.0` that the project is compatible with. If it's loaded with an incompatible version, an error is raised when the project is loaded. |
