The method of using filter with read_gds

[bsslv]

Hello. I want to use the filter parameter of read_gds.

Is this code correct? read_gds(infile_str, filter={(1, 0), (2, 0)})
I tested this code, but a specific cell only made polygons of layer 1,
BUT I know this cell has polygons of layer 2 and also this data type is "0" I checked.

How can I fix the code?
Or, When this code is correct, what else could be the problem ?

I already tested “read_gds(infile_str, filter=list({(1, 0), (2, 0)}))”

THANKS

(Misread your question). The first call is correct read_gds(infile_str, filter={(1, 0), (2, 0)}). Can you share an example with the problem so that I can investigate?
