I am trying to load a series of csv files as vectors in PyQGIS. I run this code to try to get the first one:

uri='file://D:/Saved Stuff/gulags/1.40.csv?delimiter=;&yField=y&xField=x'
layer = QgsVectorLayer(uri, '1.40', 'delimitedtext')
layer.isValid()
False

Obviously (?) it won't load when I run QgsMapLayerRegistry.instance().addMapLayer(layer). When I add the csv manually to a map it loads fine. Here is what that looks like

name;y;x;total

AMURSKII ZhELEZNODOROZhNYI ITL;51.375889;128.134147;84053

BELOMORO-BALTIISKII ITL;62.912774;34.456850;78918

BIRSKII ITL;48.999752;132.461997;11634

Can anyone help me with this?

  • What happens when you do this? uri='file://D:/Saved Stuff/gulags/1.40.csv?delimiter=%s&xField=%s&yField=%s' % (";","x","y"); – Thomas Oct 14 '15 at 17:06
  • Still gives me false. The modulo is just a standin – sfbernstein Oct 14 '15 at 17:22

Use the following as working example:

uri='file:///D:/Saved Stuff/gulags/1.40.csv?delimiter=;&yField=y&xField=x'
layer = QgsVectorLayer(uri, '1.40', 'delimitedtext')

The problem was with your URI :) (note the third slash)
