preprocess_data error in TechnologyFromStorage

[HauHe]

When applying the preprocess_data script on this step0.txt model file I get the following error:
Traceback (most recent call last): File "preprocess_data.py", line 324, in <module> main(data_format, data_infile, data_outfile) File "preprocess_data.py", line 229, in main if value > 0.0: TypeError: '>' not supported between instances of 'str' and 'float'
It seems to be related to parameter TechnologyFromStorage.
