Hi, thanks for posting this. We were fairly certain we had decent Python support on Raspberry Pi via piwheels.org and that normally you should only need to do the last step. We checked the most recent build report and saw that the build failed for 3.4. Are you using 3.4?

These steps seem correct as a fallback, but ideally if just pip-installing the SDK is not working then there's a problem that we should address.

Edit: I've been informed that 3.4 no longer has LTS and supporting it is unlikely.

I tried to use with Python 2.7. When I use Python3.7 install works good.

Here is my Raspberry Pi 4 details.

aha, piwheels.org does not supply python 2.7 wheels:

Wheels are provided for Raspbian Jessie (Python 3.4), Raspbian Stretch (Python 3.5) and Raspbian Buster (Python 3.7)

that explains why it's necessary to compile for 2.7 but not 3.7.
