Another example:
This one fails. Removing the header fixes the issue. Interestingly, the behavior changes depending on whether or not you are using a debugger.

OK, so this is a limitation of what we can ask of pandas.
A workaround:
data_sources:
# Initial setup
initial_tech_capacity_params:
source: data_sources/initial_capacity_techs_kw.csv
rows: [nodes, techs, parameters]
columns: [values]
drop: values
I can only reproduce this issue with your second example. The first one loads just fine.

Odd, that's the one I saw as most problematic. I'll give an update if I can reproduce it...
For the second: I would like to propose that this type of "dropping" should be the standard, to ensure the files given to the model are "stand alone". Otherwise, you'd need to always consult two files. This way, you have good data practices "baked in".
What do you think?
It's impossible to make it standard as we have to know whether the top row is data or not. As soon as you say it isn't data (columns: [...]) then it becomes an index / column and you wouldn't want that data deleted automatically if you actually wanted it to be part of you model. So the only way to handle it consistently is to force the user to be explicit or to tell them that there must always be a header and that if they miss it then their top row of data may be silently(?) lost...

Hmmm, that is true... The only way to make it possible would be to force one type of table (i.e. rows only), which would make the input very inflexible).
Plan: enforce a header to always exist in a CSV, even if it is just one row. We will set header=0
as the bare minimum internally.
What happened?
Loading a file with multiple rows and multiple columns adds fake indexes sometimes.
See the file:
Loaded via:
In this case, a fake index called
techs
will be added.Which operating systems have you used?
