6 months ago When cudf is imported without a CUDA driver (as it is in non-GPU enabled Colab environments), the above warning occurs.
datashader has an optional dependency on cudf, and will import it if found.
Since cudf-cu12 is installed by default in Colab, we get this warning in Colab when importing datashader.
This can be verified by starting a fesh Colab notebook, pip installing datashader and then attempting to import.
I can also replicate this warning on my local machine (which is NVIDIA free) by pip installing cudf-cu12 and then importing datashader
Circa May 8 we started receiving the following warnings when importing Ecoscope within Colab.
