When processing L2 NO2 data from TROPOMI at harp, there is a problem importing the data. Have reinstalled harp, created a new conda environment, can’t get a solution. Looking forward to an answer

Please make sure you don’t have an empty directory named ‘harp’ on your python path.

You can check which locations to look for such an empty directory with:

```auto
import sys
print(sys.path)

```
