I followed the installation guide here:
I ran a test script like this:
import Adafruit_BME280
sensor = Adafruit_BME280.BME280(t_mode=Adafruit_BME280.BME280_OSAMPLE_8,
p_mode=Adafruit_BME280.BME280_OSAMPLE_8,
h_mode=Adafruit_BME280.BME280_OSAMPLE_8)
degrees = sensor.read_temperature()
pascals = sensor.read_pressure()
print (degrees)
print (pascals)
The output of that is:
25.034087635501418
99871.16464771295
However, when I try to get Weewx to read the data from the BME280, the
output of the syslog on a restart never gets past these lines:

In my weewx.conf, these added lines do not seem to work.

prep_services = weewx.engine.StdTimeSynch
data_services = ,
process_services = weewx.engine.StdConvert,
weewx.engine.StdCalibrate, weewx.engine.StdQC,
weewx.wxservices.StdWXCalculate, user.weather34.Weather34RealTime

weewx.restx.StdCWOP, weewx.restx.StdWOW, weewx.restx.StdAWEKAS
report_services = weewx.engine.StdPrint, weewx.engine.StdReport
# following line is the BME280 pressure sensor
data_services = user.bme280.bme
I have to comment out the BME section and the data_services line in the
Engine section in order to get Weewx to work properly again.
Any ideas on my problem?
