Error Encountered while using pybna python library "InvalidTextRepresentation: malformed array literal: "{6'0"}" DETAIL: Unexpected array element.'

Hi spencerrecneps@ I was using the python pybna 1.0.2 library to calculate the stress for Portland, Oregon. I have overwritten the boundary shape file, the library successfully read the boundary shape file, imported census blocks, and received census jobs data using the below line of codes.

City Boundary is available here: https://gis-pdx.opendata.arcgis.com/datasets/1559e31273654eb9858397861f1fdefa/explore?location=45.629289%2C-122.551444%2C10.44

''' i = pybna.Importer(config="config.yaml") i.import_boundary('city_of_portland_boundary.shp', overwrite=True) i.import_census_blocks(fips=41, overwrite=True) i.import_census_jobs("received.neighborhood_census_block_jobs",state="OR", overwrite=True) '''

After the above lines of code, when I was trying to import osm network using the below line of code, I encountered the error- ''' i.import_osm_network() i.import_osm_destinations() '''

I am using the first time of this library. Any help to solve this issue is greatly appreciated!

Hi @mintu07ruet, sorry this took a while to respond. This may been fixed from updates in https://github.com/tooledesign/pybna/pull/83. Can you verify and let me know if it still persists.
