When I tried to import the package (import refinitiv.dataplatform as rdp), I kept telling that data classes could not be found. I reinstalled refinitiv-dataplatform several times and still got the same result.
It has not yet progressed to the verification step. The first step is to import the development package, there is a problem, please see the screenshot.
Dataclasses (https://docs.python.org/3/library/dataclasses.html) were introduced in Python 3.7.
The PyPi page for RDP states that it requires Python > 3.6 refinitiv-dataplatform · PyPI
The log above shows that you are using v3.6.4
Please upgrade your python version e.g. to v3.8 or v3.9
