Cannot seem to query time series containers with the new GridDB Python Client?-CodePudding

Querying collection containers works fine, but querying any sort of time series container -- even just a simple select * -- causes a Segmentation Fault.

Here is what my Dockerfile looks like:

Here is the output of gdb when running the griddb sample code sample2.py

If I query the collection containers, no seg fault. Any ideas?

CodePudding user response：

Lookin at the docker file, the issue maybe because both Python 3.6 and Python 3.10 are installed. Python 3.6 is used for building but Python 3.10 is used instead for running the sample, as follows:

You install Python 3.10 : build python from source code. Then you install pandas with Python 3.10.
You install Python 3.6 : by using yum. You do not install pandas with Python 3.6.
You install Python Client : system use python 3.6 to build Python Client
You run sample2.py with Python 3.10.
