This isn't really a question since this might be the expected behavior, but since I spent a good chunk of time pinpointing the problem, figured I'd share.
I was playing around with SEDFs and had some issues plotting a SEDF that had NaT datetime values. The error it gave was
- AttributeError: Can only use .str accessor with string values, which use np.object_ dtype in pandas
This seems to only be an issue if all the values in a datetime column are NaT. I won't go into details why, but there was a datetime column that didn't have a single valid datetime value, all values were null/NaT.
So, the following line of code was causing the error
sdf<SPAN class="punctuation token">.</SPAN>spatial<SPAN class="punctuation token">.</SPAN>plot<SPAN class="punctuation token">(</SPAN>map_widget<SPAN class="operator token">=</SPAN>m1<SPAN class="punctuation token">)</SPAN><SPAN class="line-numbers-rows"><SPAN></SPAN></SPAN>
