Re: [Pysparse-users] Compiling pysparse on a 64 bit machine

[Artur P. <art...@gm...>]

Thank you for the help, again.

The error it gives is:

IndexError: first index is invalid

And the error comes up when I try to assign a value to an entry of the
B matrix in this way:

B[ GN[e,n,m], GN[e,i,j] ] += something

B is the sparse matrix and GN is a 3d array.

I have checked that the values of GN are correct. The exact same code
works on another machine. I even tried a simpler code and it gives the
same error. The strange thing is that if I try to do it in ipython,
line by line, it works. Even if I assign a the value of GN to another
variable, as:

a = GN[e,n,m]
b = GN[e,i,j]

and then try:

B[a,b] += something

it does not work also, or if I assing to a and b constant values as:

a = 1
b = 2

B[a,b] += something

It only works if I do:

B[1,2] += something

Any help?

Thank you
