As mentioned in a similar thread :
Serverless environments such as App Engine, Cloud Functions and Cloud Run, run in a sandbox, similar to gVisor. This sandbox protects the system from
malicious calls and blocks some low level instruction. This one to get the CPU capabilities should be discarded.
I got the same when I ran Tensorflow Serving on Cloud Run.
This error has been discussed in the answer:
The warning is just telling you that OpenBLAS, which is a dependency of Pandas, is not able to determine some settings of Cloud Function environments,
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.
For more information, you can refer to a well explained answer on the similar issue.
