What happened?

There's an issue with the installation of scanpy in Colab when working without GPUs, only using the CPU, which is my intention to avoid consuming computational units. This doesn't allow me to import scanpy; I get the following error:

---

ImportError Traceback (most recent call last)
/usr/local/lib/python3.10/dist-packages/cupy/init.py in
16 try:
---> 17 from cupy import _core # NOQA
18 except ImportError as exc:

10 frames
ImportError: libcuda.so.1: cannot open shared object file: No such file or directory

The above exception was the direct cause of the following exception:

ImportError Traceback (most recent call last)

17 from cupy import _core # NOQA

ImportError:

Failed to import CuPy.

If you installed CuPy via wheels (cupy-cudaXXX or cupy-rocm-X-X), make sure that the package matches with the version of CUDA or ROCm installed.

On Linux, you may need to set LD_LIBRARY_PATH environment variable depending on how you installed CUDA/ROCm.
On Windows, try setting CUDA_PATH environment variable.

Check the Installation Guide for details:
https://docs.cupy.dev/en/latest/install.html

Original error:
ImportError: libcuda.so.1: cannot open shared object file: No such file or directory

NOTE: If your import is failing due to a missing package, you can
manually install dependencies using either !pip or !apt.
