yzhliu commented on issue #4382: [TOPI] Fix flaky testcase for floor div URL: https://github.com/apache/incubator-tvm/pull/4382#issuecomment-556989979 @tqchen I'm afraid the flaky is not from that around 0.5, I find a case: ```python import tvm import topi import numpy as np dtype = "float32" A = tvm.placeholder(name="A", shape=(1,), dtype=dtype) B = tvm.placeholder(name="B", shape=(1,), dtype=dtype) C = topi.floor_divide(A, B) with tvm.target.create("llvm"): s = topi.generic.schedule_broadcast(C) foo = tvm.build(s, [A, B, C], "llvm") ctx = tvm.cpu() #a = np.array([-89.50379]).astype(dtype) #b = np.array([7.458649]).astype(dtype) a = np.array([94.90735]).astype(dtype) b = np.array([0.6731018]).astype(dtype) lhs_nd = tvm.nd.array(a, ctx) rhs_nd = tvm.nd.array(b, ctx) out_nd = tvm.nd.array(np.empty((1,)).astype(C.dtype), ctx) foo(lhs_nd, rhs_nd, out_nd) print("tvm", out_nd.asnumpy()) print("np", np.floor_divide(a, b)) print("python", 94.90735 / 0.6731018) ``` ``` $ python test.py tvm [141.] np [140.] python 140.99999435449436 ```
