OSError: [E053] Could not read config.cfg from en_core_web_md-3.0.0a1/config.cfg

Hi,

I installed all the right versions of the specified dependencies but I get this error:

`OSError: [E053] Could not read config.cfg from en_core_web_md-3.0.0a1/config.cfg
`

A lower version of spaCy might resolve this error (see: https://github.com/explosion/spaCy/issues/7453). But this causes a new error:

`KeyError: "[E002] Can't find factory for 'tok2vec'. This usually happens when spaCy calls `nlp.create_pipe` with a component name that's not built in - for example, when constructing the pipeline from a model's meta.json. If you're using a custom component, you can write to `Language.factories['tok2vec']` or remove it from the model meta and add it via `nlp.add_pipe` instead."`

Can someone please help with this? Thanks!
