[Qgis-user] contour plugin and dependencies

[Michael.Dodd]

Have tried removing qgis (the full package) and installing via osgeo4w making sure all the correct bits were there.  it appears there are some bugs as when i was deleting the full package i saw the correct parts such as numpy etc being deleted even though the plugin said they were not present.

anyway first attempt via osgeo4w the contour plugin complained that matplotlib was missing, infact it was not missing but i reinstalled it again anyway.  this time contour plugin said everything was present and correct.  unfortunately it still failed to work giving a python error saying it could not parse the data.  as far as i can see there is nothing wrong with the data, it is a simple small datafile that other parts of the program deal with ok.

Hi Michael

It is very likely that it is due to missing dependencies.  The contour plugin relies on python numpy and matplotlib modules. I'm pretty sure these can be installed from osgeo4w, though its been a while since I've done so (I'm working on linux).  I've no idea why the osgeo4w installer did not work - possibly a local firewall or web proxy issue?

Thanks for noting that the error message is not clear.  If you think it is not numpy or matplob missing (which I guess will show as an import error) could you let me know please?

Thanks
Chris

I am using qgis 2.8.1 and contour 1.3 on win8.1 64bit but plugin comes up with a python error and does not produce any contours.

I assume the error is due to missing dependencies although it does not say this.  If it is due to missing python dependencies then how do you load these, is it via osgeo4w installer?  when i tried to download osgeo4w installer it did not seem to be available (web link never connected).
