Tutorial 11 EPW files issues

[mvavrovic]

Hello! I'm trying to get this to run, but seem to have some kind of data format error. Is this a know problem / version / os issue?

Thanks!

Exception has occurred: ValueError
cannot assemble the datetimes: day is out of range for month, at position 59. You might want to try:
    - passing `format` if your strings have a consistent format;
    - passing `format='ISO8601'` if your strings are all ISO8601 but not necessarily in exactly the same format;
    - passing `format='mixed'`, and the format will be inferred for each element individually. You might want to use `dayfirst` alongside this.

The above exception was the direct cause of the following exception:

This tutorial worked with bifacial_radiance v0.4.2 but is broken in v0.4.3.... need to investigate this. (and need to include tutorial .py files in our test matrix prior to new releases in the future..)

Thanks for the quick fix! I figured it had to do with leap years, didn't expect a fix before I even report my findings :)
