file import problem

[Mhdx20]

Hello,
I am trying to import my files which are in .gpkg format.
rpg15 = gpd.read_file(path_rpg15)
rpg16 = gpd.read_file(path_rpg16)
rpg17 = gpd.read_file(path_rpg17)
rpg18 = gpd.read_file(path_rpg18)
rpg19 = gpd.read_file(path_rpg19)

But I always get an error message like this:

CPLE_OpenFailedError Traceback (most recent call last)
File fiona_shim.pyx:83, in fiona._shim.gdal_open_vector()

File fiona_err.pyx:291, in fiona._err.exc_wrap_pointer()

CPLE_OpenFailedError: rpg_15.gpkg: No such file or directory

During handling of the above exception, another exception occurred:

DriverError: rpg_15.gpkg: No such file or directory

It seems to me that the fiona package is installed. Can you help me please?

DriverError: rpg_15.gpkg: No such file or directory

It looks as if the file you want to open does not exist. You can check if a file exists with os.path.exists(path_rpg15).

@rbuffat
Yes the file exists in my directory, but I don't understand why it can't find it

[rbuffat]

@Mhdx20 If you use a relative path and your current working directory is not the directory with the data files, the file will not be found. You could either use absolute paths or ensure that your current working directory corresponds to the directory with the data files.

@rbuffat Thank you very much, it was indeed related to a directory problem, it's fixed.

I have an error on my screen. I want to create a single geometry column with the following lines of code:
rpg15_19.loc[rpg15_19.geometry_x != None, 'geom'] = rpg15_19['geometry_x']
rpg15_19.loc[rpg15_19.geometry_y != None, 'geom'] = rpg15_19['geometry_y']
rpg15_19.loc[rpg15_19.geometry != None, 'geom'] = rpg15_19['geometry']

I get an error message like this:
KeyError Traceback (most recent call last)
