I got this error when I had try to install and load cityjson in qgis 3.10 ltr

Couldn't load plugin 'CityJSON-loader' due to an error when calling its classFactory() method

ValueError: could not convert string to float: '6378137.0.'

Hi Navid,

This is a really weird issue. It doesn't seem to be affected by any specific data. Sounds like there is something wrong with the pyproj package in QGIS.

Nevertheless, in those cases one of the main suspect if the regional settings of your operating system. May I ask if that's on Linux, Windows or macOS and what are your regional settings (e.g.: is the decimal point a dot or a comma)?

Hi, I didn't understand what is your question? Regional setting, you mean my local setting, I did not change any regional setting in qgis, but I think it would be comma, however I should check again my setting
