Hello all,
I have a sample code from tvm offical site below. I want to build
thousands of operators in the same process. But i found there is memory leak
and the memory usage is increasing. I thought after the build of one operator
was finished, the corresponding resource should be freed. Do you have any
advice? Can i free memory manually after building a operator?
Thanks a lot in advance!
Sample code:
`
import os, psutil
import tvm
def tvm_build():
n = 2
A = tvm.placeholder((n,), name='A')
B = tvm.placeholder((n,), name='B')
C = tvm.compute(A.shape, lambda *i: A(*i) + B(*i), name='C')
s = tvm.create_schedule(C.op)
m = tvm.lower(s, [A, B, C], name="test_add")
rt_mod = tvm.build(m, target="llvm")
print("ref of tvm, before=" + str(sys.getrefcount(tvm)))
del tvm
print("ref of tvm, after=" + str(sys.getrefcount(tvm)))
def main():
process = psutil.Process(os.getpid())
for i in range(0, 1000):
tvm_build()
print('i='+str(i)+', Used Memory:', process.memory_info().rss / 1024
/ 1024, 'MB')
