I believe this is due to the recent release of Cython 3.0.0, which the package you’re installing apparently isn’t ready for ![]()
Try the following:
$ echo "Cython<3" > cython_constraint.txt
$ PIP_CONSTRAINT=cython_constraint.txt pip install "ai-core-sdk[aicore-content]"
Note that you need to set the constraint file via the environment variable so that it propagates to the build env.
