Python 3.6 is unable to find Python's smbus module

(1/3) > >>

gatorback:
smbus is required for a relayboard and is a hurdle to overcome before trying the suggestion to create an python extension.


From the python console smbus is not found with (sudo) Python3.6 and returns:
 

--- Code: --->>>import smbus
ModuleNotFoundError: No module named 'smbus'
--- End code ---

python 2.7 on the other hand loads smbus.

>>> import smbus
>>>

Why is Python 3.6 not successful finding smbus and what will remedy the issue?  What diagnostics can be performed to determine root-cause?

Juanito:
Is it smbus2?

gatorback:
Good question!  How can one determine version of the smbus extension?

Does a version3 of py-smbus exist?

Juanito:
if you look at:
http://tinycorelinux.net/7.x/armv6/tcz/py-smbus.tcz.info
http://tinycorelinux.net/7.x/armv6/tcz/py-smbus.tcz.list

..you can see the details.

What I meant was that the python package available from pip for python3.6 might be called smbus2

To compile it I guess you need:
