Python REPL中与shell的python -m及spacy下载命令等效的命令是什么？

Hey there! Let's tackle your two questions one by one:

Absolutely! The python -m command lets you execute a module as a standalone script, and in the REPL, you can replicate this behavior using Python's built-in runpy module. Here's how it works:

• First, import the runpy module: import runpy
• Use runpy.run_module() with your target module name, and set run_name='__main__' to match the execution context that python -m uses.

For example, if you'd normally run python -m json.tool in your shell, in the REPL you'd do:

import runpy
runpy.run_module('json.tool', run_name='__main__')

This runs the json.tool module exactly like the shell command does.

You have two clean options here:

Option 1: Use runpy (mirroring the python -m approach) #

You can pass the download and model name arguments directly via the args parameter:

import runpy
runpy.run_module('spacy', run_name='__main__', args=['download', 'en_core_web_sm'])

Option 2: Call spaCy's CLI function directly #

SpaCy exposes its CLI commands as reusable Python functions in the spacy.cli module. This is often more readable than using runpy:

import spacy.cli
spacy.cli.download('en_core_web_sm')

Just a quick note: Make sure your REPL session has the right permissions to download and install the model (you might need a virtual environment or elevated privileges if installing system-wide).
