spacy 2.3.9 does not provide the extra 'ray'

[danh8012]

When I run "pip install -U spacy[transformers,ray,lookups]", always gives that WARNING, and not found 'ray' packaged installed.
My commands:

python -m venv .my_env
.my_env\Scripts\activate
(.my_env) > pip install -U spacy[transformers,ray,lookups]

Results:

WARNING: spacy 2.3.9 does not provide the extra 'ray'
WARNING: spacy 2.3.9 does not provide the extra 'transformers'

How to fix it?

I have converted this to a discussion, since this is not a bug in spaCy. Note that spaCy 2 gets installed:

WARNING: spacy 2.3.9 does not provide the extra 'ray'
WARNING: spacy 2.3.9 does not provide the extra 'transformers'

spaCy ray and transformers are only supported in spaCy 3. Most likely you are using a very old Python version for which no spaCy 3 packages are available.

Try this without ray? (The spacy-ray package is very experimental / alpha / not ready for production use and now also quite out-of-date. You probably don't want to use it.)

But I saw that in here https://spacy.io/usage/training#parallel-training

Sorry that you have run into this! We will remove this section from the spaCy documentation.

Thanks for catching this! I remember that we'd removed this section last year, but it looks like it accidentally got restored in a website upgrade.
