I am trying to find a basis for the nullspace of some matrix $A$ in sympy of size (384, 120). When calling A.nullspace() The RAM usage gradually rises up to the 60GB that I have, and then the kernel dies.The matrix consists of elements that are just 1,-1,0 and mostly zero.I create the matix like this: A = sympy.Matrix(vectors_list)
where every element of vectors_list is a tuple of elements of type sympy.core.numbers.I tried setting the environment variables "SYMPY_USE_CACHE", "SYMPY_INT_TRACE" to "no" and it did not make a change. I also posted here: https://stackoverflow.com/questions/49997220/sympy-memory-explosion-when-computing-nullspace-of-a-small-matrix?noredirect=1# without luck. What can I do more? -- You received this message because you are subscribed to the Google Groups "sympy" group.
