Hello netcdf-experts,
currently i am working on a data analysis program which requires reading
different netcdf files (version 3 and 4).
To keep the installation requirements slim (the python script should run on
various machines) it would be desirable to use as few libraries as possible.
If the Scientific.IO.NetCDF library is used everything works fine.
With the netCDF4 python library (version 1.1.5), the following error occurs:
Traceback (most recent call last):
File "advection.py", line 157, in <module>
profile = wp_advect("wpl_20150602_002408.nc")
File "advection.py", line 143, in __init__
self.u_vel = self.f.variables["WP_U"][:]
File "netCDF4.pyx", line 3097, in netCDF4.Variable.__getitem__
(netCDF4.c:42713)
File "netCDF4.pyx", line 3118, in netCDF4.Variable._toma (netCDF4.c:43134)
ValueError: invalid literal for float(): 3.402823466e+38F
The relevant code snippet:
def __init__(self, filename):
""" """
self.filename = filename
#self.f = netCDF4.Dataset(filename, 'r', format='NETCDF4_CLASSIC')
self.f = NetCDF.NetCDFFile(filename, 'r')
self.time_list = self.f.variables["Timestamp"][:]
self.height = self.f.variables["WP_Height"][:]
self.u_vel = self.f.variables["WP_U"][:]
self.v_vel = self.f.variables["WP_V"][:]
Thank you for your help.
Kind regards
Martin Radenz
