New issue 899: my_plugins.py file tries to find fields on initialization and fails if not found

Devin Silvia:

my_plugins.py used to be able to contain user-defined fields that would only actually be created if specifically requested.  Now, it would appear that yt tries to load all of the fields in my_plugins.py upon initialization.  Since some fields only can be defined if certain fields are in the data, this does not seem like the desirable behavior, as you would need a my_plugins.py file that is unique to the dataset that you're analyzing.
