Atom S3 - Intermittent Driver(?) Errors w/ MLX90614 Sensor in NCIR

[wmatkins]

WTH, works sometimes when editing - then it doesn't. See error messages below.
Am I wrong in interpreting this as not UIFlow errors but incompatibility with the NCIR Unit?

Intermittent random "<stdin>" line numbers, but consistent driver/mlx90614.py errors.
Any ideas about what is going on or how to resolve? Thanks.

Traceback (most recent call last):
