spacy 3.0.6 installation failure

[MisbahKhan789]

Hello,

I am trying to install spacy 3.0.6 but am receiving some errors during the installation. I have done this install numerous times in the past without any issues and am not sure what's causing the issue this time.

The code I am running is !pip install spacy==3.0.6

I am looking for a solution to this problem. The error that I am receiving is as follows:

The installation error appears to be caused by a change in the cython package that was introduced in v3.0.0. Could you try the following?

pip install Cython==0.29.36
pip install spacy==3.0.6 --no-build-isolation

That should prevent the cython package from being upgraded during the installation, thereby avoiding the compiler error.

In my case solved with the solution provided here: #13449 (comment)
The downgrade didn't do anything
