Hello, I am a first-time user of matplotlib.
When trying to run the plotmap.py example, the following traceback is generated:
>plotmap.py
Traceback (most recent call last):
File "C:\Documents and Settings\jim.vickroy\My Documents\Projects\High-latitudes D-region\plotmap.py", line 13, in <module>
topoin = load('etopo20data.gz')
File "C:\Python25\Lib\site-packages\matplotlib\mlab.py", line 1252, in load
fh = cbook.to_filehandle(fname)
File "C:\Python25\Lib\site-packages\matplotlib\cbook.py", line 236, in to_filehandle
fh = gzip.open(fname, flag)
File "C:\Python25\lib\gzip.py", line 49, in open
return GzipFile(filename, mode, compresslevel)
File "C:\Python25\lib\gzip.py", line 95, in __init__
fileobj = self.myfileobj = __builtin__.open(filename, mode or 'rb')
IOError: [Errno 2] No such file or directory: 'etopo20data.gz'
How do I obtain this file and where should it reside?
I have downloaded proj446_win32_bin.zip and unzipped it, but I do not see any such file.
I have also attempted to search this user-group archive for references to "etopo20data.gz" but repeatedly get an "Unable to connect to Search Server" error so I do not know what I'm doing incorrectly.
I have installed:
- matplotlib-0.91.2.win32-py2.5.exe
- basemap-0.9.9.1.win32-py2.5.exe
- httplib2-0.4.0.zip
for use with Python 2.5.1.
I apologize if this has been previously addressed.
Thanks,
