[sage-support] Problem of memory
Hello, I'm a beginner in python and sage. I'm trying to solve a system of ODE by the newton method with python by sage. But i have a problem of memory with Lisp or Maxima when the hessian matrix is calculated. The process doesn't use the whole 12 giga RAM memory of my 64bits linux system and crash with this message error: Maxima ERROR: kill(sage297)$(%i2196) kill(sage290)$batchload(/.sage//temp/14907// interface//tmp14907-827495505);1+140260649; sage-displaysage-displaysage-displayGC Warning: Out of Memory! Returning NIL! Maxima encountered a Lisp error: Memory limit reached. Please jump to an outer point or quit program. Automatically continuing. To reenable the Lisp debugger set *debugger-hook* to nil. sage-display (%o2199) sage: Exiting SAGE (CPU time 1m15.04s, Wall time 5m48.08s). Exiting spawned Maxima process. I have installed sage for linux 64bits system. Someone can help me?

To do this, just change to the Sage directory and type: ./sage -f mpir-1.2.p4 ./sage -f atlas-3.8.3.p3 and make sure each step succeeds. William members, same problem on opensuse11.1.

[sage-support] Re: How can I remove or delete worksheet written by pub?
Click Publish then Stop publishing on the editable version of the worksheet. On Tue, Aug 11, 2009 at 4:51 PM, NoSyudon...@gmail.com wrote: Thanks to reply my post.

I test the something not use notebook web interface directly. And there is a problem that if I publish the worksheet, there is a new published worksheet by pub id in published worksheet list. So I want to remove that worksheets, but I don't know the pub password or can't login. I just delete the worksheet directory in .sage/ sage_notebook/pub folder, but it didn't work. Now I fix the problem to use some function, but I want to remove the published worksheets written by pub. How can I do? I think deleting published worksheets is not implemented at present, unfortunately. This will get fixed in October. Also, that the worksheet appears to be published by pub is a bug.

[sage-support] Why do I get Too many open files?
Hello, I am opening many netcdf files, getting one variable and closing each file in each loop: ctt=[] for j in fileList1: for f in j: ncfile=netcdf_file(path+f,'r') ctt.append( ncfile.variables['Cloud_Top_Types'][:] ) ncfile.close() However, I get the following error message: Traceback (most recent call last):ncfile2=netcdf_file(path +f,'r') File /Users/aguillau/local/sage/sage/local/lib/python2.5/site- packages/scipy/io/netcdf.py, line 44, in __init__ File /Users/aguillau/local/sage/sage/local/lib/python2.5/site- packages/scipy/io/netcdf.py, line 80, in _parse File /Users/aguillau/local/sage/sage/local/lib/python2.5/site- packages/scipy/io/netcdf.py, line 136, in _var_array File /Users/aguillau/local/sage/sage/local/lib/python2.5/site- packages/scipy/io/netcdf.py, line 188, in _read_var File /Users/aguillau/local/sage/sage/local/lib/python2.5/site- packages/scipy/io/netcdf.py, line 260, in __init__ EnvironmentError: [Errno 24] Too many open files This loop works if fileList is smaller than 120 in size and crashes if it's larger.
