I get the warning
OpenBLAS WARNING - could not determine the L2 cache size on this system, assuming 256k
in the logs of the "LOGS" tab of the Cloud Function.
There is already a Q/A on this on Stack Overflow at AppEngine warning - OpenBLAS WARNING - could not determine the L2 cache size on this system, but it is not asked for a Google Cloud Function, only for the Google App Engine.
I wonder how I can get rid of this warning in a Google Cloud Function and whether I should care at all?
- It is just a warning anyway and the quite heavy Cloud Function (with a lot of calculations + saving 50 MB csv, 700 MB needed RAM, 1 GB allocated, 540s timeout time) runs through anyway. Doing nothing can be an accepted answer.
- Perhaps I can find the L2 cache size somewhere in the settings, which system is meant here?
The warning is just telling you that OpenBLAS which is a dependency of Pandas is not able to determine some settings of Cloud Function environment, most likely due to Cloud Function runs on virtualized environments. I suggest that you just ignore the warning as it is not an issue in Cloud Function.
