[web2py] ImportError: No module named ...
Hi, I am facing a problem on Windows installation of web2py. When trying to run applications I get the following error: ImportError: No module named ... ... replaced by a model I have used in the import statement in default.py All the modules I have used are installed and thety can be imported when called from the python console or with any ordinary python application by 'python foo.py' type of a call. It seems web2py does not understand the paths the same way as my python installation. Any ideas how this could be fixed? Many thanks. -- You received this message because you are subscribed to the Google Groups "web2py-users" group. To post to this group, send email to web...@googlegroups.com.

[web2py] Re: ImportError: No module named ...
Thanks for the reply - I think a typo in my original message might
have
given a wrong impression of the problem I am facing.
Instead of '... replaced by a model I have used in the import
statement'
it should have said '... replaced by a MODULE I have used...', for
example:
import numpy
But then when trying too run the application in web2py I get an error:
ImportError: No module named numpy
I should also add that the same applications work fine on web2py in my
Ubuntu 9.10 box.
I tried to add
numpy = local_import('numpy') to the beginning of the default.py to no
avail (if I understood your advice correctly).

[web2py] Re: ImportError: No module named ...
Thanks - I did not realise the binary vs source thing. When changing
from Windows binary to the source everything works as expected. Great!
Many thanks for you help.

[web2py] read a blob to numpy array
I need to read a csv file consisting of one row, split its contents to
values and then do some calculations with these values and store
results of these calculations in a database that already has some
fields filled and a record id. I would like the users to be offered a
file open dialog for choosing the file. I am thinking of saving the
csv file to a blob field with (Field('csvfile','upload') but I am
uncertain how can I read the contents of the blob and convert it to a
numpy array for calculations.
Can the blob be treated as a file stream?
In addition, my simple attempts to try to retrieve the contents of the
blob (opening the file saved) appear to result in an error that the
file is not found when I try to reference it by the 'csvfile' name
saved. Appadmin shows a 'file' link that offers to download the file -
but I have not been able to solve how this works.
Any suggestions? Or alternative solutions to solve the problem?
Many thanks, Kari

[web2py] Re: read a blob to numpy array
I apparently solved this. I needed to add "uploads/" between the
request.folder and the filename I got from the blob object when
concatenating the path since the files are stored in the "uploads"
folder. I missed this in my first attempts.
