这是 TVM 算子清单（TOPI）的入门教程。 TOPI 提供了 numpy 风格的通用操作和 schedule，其抽象程度高于 TVM。本教程将介绍 TOPI 是如何使得 TVM 中的代码不那么样板化的。
import tvm import tvm.testing from tvm import te from tvm import topi import numpy as np
基本示例
让我们回顾一下行求和操作（例如 B = numpy.sum(A, axis=1)）。要计算二维 TVM 张量 A 的行之和，应指定符号运算以及 schedule，如下所示：
n = te.var("n")
m = te.var("m")
A = te.placeholder((n, m), name="A")
k = te.reduce_axis((0, m), "k")
B = te.compute((n,), lambda i: te.sum(A[i, k], axis=k), name="B")
s = te.create_schedule(B.op)
输入以下命令查看可读的 IR 代码：
print(tvm.lower(s, [A], simple_mode=True))
输出结果：
@main = primfn(A_1: handle) -> ()
attr = {"from_legacy_te_schedule": True, "global_symbol": "main", "tir.noalias": True}
buffers = {A: Buffer(A_2: Pointer(float32), float32, [(stride: int32*n: int32)], [], type="auto")}
buffer_map = {A_1: A}
preflattened_buffer_map = {A_1: A_3: Buffer(A_2, float32, [n, m: int32], [stride, stride_1: int32], type="auto")} {
allocate(B: Pointer(global float32), float32, [n]), storage_scope = global;
for (i: int32, 0, n) {
B_1: Buffer(B, float32, [n], [])[i] = 0f32
for (k: int32, 0, m) {
B_1[i] = (B_1[i] + A[((i*stride) + (k*stride_1))])
}
}
}
然而，必须为这样一个常用的操作定义 reduce 轴，并用te.compute定义显式计算。幸运的是，可以用topi.sum（类似numpy.sum）来替换这两行：
C = topi.sum(A, axis=1) ts = te.create_schedule(C.op) print(tvm.lower(ts, [A], simple_mode=True))
输出结果：
@main = primfn(A_1: handle) -> ()
attr = {"from_legacy_te_schedule": True, "global_symbol": "main", "tir.noalias": True}
buffers = {A: Buffer(A_2: Pointer(float32), float32, [(stride: int32*n: int32)], [], type="auto")}
buffer_map = {A_1: A}
preflattened_buffer_map = {A_1: A_3: Buffer(A_2, float32, [n, m: int32], [stride, stride_1: int32], type="auto")} {
allocate(A_red: Pointer(global float32), float32, [n]), storage_scope = global;
for (ax0: int32, 0, n) {
A_red_1: Buffer(A_red, float32, [n], [])[ax0] = 0f32
for (k1: int32, 0, m) {
A_red_1[ax0] = (A_red_1[ax0] + A[((ax0*stride) + (k1*stride_1))])
}
}
}
Numpy 风格的算子重载
可用 topi.broadcast_add 添加两个张量（其 shape 可广播，且是特定的）。TOPI 为此类常见操作提供了算子重载使其更简短。例如：
x, y = 100, 10 a = te.placeholder((x, y, y), name="a") b = te.placeholder((y, y), name="b") c = a + b # 等价于 topi.broadcast_add d = a * b # 等价于 topi.broadcast_mul
TOPI 使用相同的语法重载，将原语 (int, float) 广播到张量 d - 3.14。
通用调度和融合操作
前面已经展示了 TOPI 如何使我们免于用低级 API 编写显式的计算过程，但调度过程还是和以前一样。TOPI 还基于给定的上下文提供了更高级的调度方案。可以仅用 topi.generic.schedule_reduce 调度下面以 topi.sum 结尾的一系列操作，以 CUDA 为例：
e = topi.elemwise_sum([c, d])
f = e / 2.0
g = topi.sum(f)
with tvm.target.cuda():
sg = topi.cuda.schedule_reduce(g)
print(tvm.lower(sg, [a, b], simple_mode=True))
输出结果：
/workspace/python/tvm/target/target.py:377: UserWarning: Try specifying cuda arch by adding 'arch=sm_xx' to your target.
warnings.warn("Try specifying cuda arch by adding 'arch=sm_xx' to your target.")
@main = primfn(a_1: handle, b_1: handle) -> ()
attr = {"from_legacy_te_schedule": True, "global_symbol": "main", "tir.noalias": True}
buffers = {a: Buffer(a_2: Pointer(float32), float32, [10000], []),
b: Buffer(b_2: Pointer(float32), float32, [100], [])}
buffer_map = {a_1: a, b_1: b}
preflattened_buffer_map = {a_1: a_3: Buffer(a_2, float32, [100, 10, 10], []), b_1: b_3: Buffer(b_2, float32, [10, 10], [])} {
allocate(T_divide_red: Pointer(global float32), float32, [1]), storage_scope = global;
attr [IterVar(threadIdx.x: int32, [0:1024], "ThreadIndex", "threadIdx.x")] "thread_extent" = 1024;
allocate(T_divide_red.rf: Pointer(local float32), float32, [1]), storage_scope = local;
allocate(reduce_temp0: Pointer(local float32), float32, [1]), storage_scope = local {
T_divide_red.rf_1: Buffer(T_divide_red.rf, float32, [1], [], scope="local", align=4)[0] = 0f32
for (k0.k1.fused.k2.fused.outer: int32, 0, 10) {
if @tir.likely((((((k0.k1.fused.k2.fused.outer*64) + floordiv(threadIdx.x, 16)) < 625) && (((k0.k1.fused.k2.fused.outer*64) + floordiv(threadIdx.x, 16)) < 625)) && (((k0.k1.fused.k2.fused.outer*64) + floordiv(threadIdx.x, 16)) < 625)), dtype=bool) {
T_divide_red.rf_1[0] = (T_divide_red.rf_1[0] + (((a[((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x)] + b[((floordiv(floormod(((k0.k1.fused.k2.fused.outer*12) + floordiv(threadIdx.x, 2)), 50), 5)*10) + floormod(((k0.k1.fused.k2.fused.outer*4) + threadIdx.x), 10))]) + (a[((k0.k1.fused.k2.fused.outer*1024) + threadIdx.x)]*b[((floordiv(floormod(((k0.k1.fused.k2.fused.outer*12) + floordiv(threadIdx.x, 2)), 50), 5)*10) + floormod(((k0.k1.fused.k2.fused.outer*4) + threadIdx.x), 10))]))*0.5f32))
}
}
attr [meta[tir.CommReducer][0]] "reduce_scope" = @tir.reinterpret(0u64, dtype=handle);
@tir.tvm_thread_allreduce(1u32, T_divide_red.rf_1[0], True, reduce_temp0_1: Buffer(reduce_temp0, float32, [1], [], scope="local")[0], threadIdx.x, dtype=handle)
if (threadIdx.x == 0) {
T_divide_red_1: Buffer(T_divide_red, float32, [1], [], align=4)[0] = reduce_temp0_1[0]
}
}
}
如上所示，计算的调度阶段是累积的，可以输入以下命令来查看：
print(sg.stages)
输出结果：
[stage(a, placeholder(a, 0x228afb00)), stage(b, placeholder(b, 0x22097c90)), stage(T_add, compute(T_add, body=[(a[ax0, ax1, ax2] + b[ax1, ax2])], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=broadcast, attrs={})), stage(T_multiply, compute(T_multiply, body=[(a[ax0, ax1, ax2]*b[ax1, ax2])], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=broadcast, attrs={})), stage(T_elemwise_sum, compute(T_elemwise_sum, body=[(T_add[ax0, ax1, ax2] + T_multiply[ax0, ax1, ax2])], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=elemwise, attrs={})), stage(T_divide, compute(T_divide, body=[(T_elemwise_sum[ax0, ax1, ax2]/2f)], axis=[iter_var(ax0, range(min=0, ext=100)), iter_var(ax1, range(min=0, ext=10)), iter_var(ax2, range(min=0, ext=10))], reduce_axis=[], tag=elemwise, attrs={})), stage(T_divide_red.rf, compute(T_divide_red.rf, body=[reduce(combiner=comm_reducer(result=[(x + y)], lhs=[x], rhs=[y], identity_element=[0f]), source=[T_divide[floordiv(floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10), 10), floormod(floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10), 10), floormod((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10)]], init=[], axis=[iter_var(k0.k1.fused.k2.fused.outer, range(min=0, ext=10))], where=tir.likely((((floordiv(floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10), 10) < 100) && (floordiv((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)), 10) < 1000)) && ((k0.k1.fused.k2.fused.inner + (k0.k1.fused.k2.fused.outer*1024)) < 10000))), value_index=0)], axis=[iter_var(k0.k1.fused.k2.fused.inner, range(min=0, ext=1024))], reduce_axis=[iter_var(k0.k1.fused.k2.fused.outer, range(min=0, ext=10))], tag=, attrs={})), stage(T_divide_red, compute(T_divide_red.repl, body=[reduce(combiner=comm_reducer(result=[(x + y)], lhs=[x], rhs=[y], identity_element=[0f]), source=[T_divide_red.rf[k0.k1.fused.k2.fused.inner.v]], init=[], axis=[iter_var(k0.k1.fused.k2.fused.inner.v, range(min=0, ext=1024))], where=(bool)1, value_index=0)], axis=[], reduce_axis=[iter_var(k0.k1.fused.k2.fused.inner.v, range(min=0, ext=1024))], tag=, attrs={}))]
可通过与 numpy 结果对比来验证其正确性，如下所示：
func = tvm.build(sg, [a, b, g], "cuda") dev = tvm.cuda(0) a_np = np.random.uniform(size=(x, y, y)).astype(a.dtype) b_np = np.random.uniform(size=(y, y)).astype(b.dtype) g_np = np.sum(np.add(a_np + b_np, a_np * b_np) / 2.0) a_nd = tvm.nd.array(a_np, dev) b_nd = tvm.nd.array(b_np, dev) g_nd = tvm.nd.array(np.zeros(g_np.shape, dtype=g_np.dtype), dev) func(a_nd, b_nd, g_nd) tvm.testing.assert_allclose(g_nd.numpy(), g_np, rtol=1e-5)
TOPI 还提供了常见神经网络操作，例如对优化的 schedule 进行 softmax：
tarray = te.placeholder((512, 512), name="tarray")
softmax_topi = topi.nn.softmax(tarray)
with tvm.target.Target("cuda"):
sst = topi.cuda.schedule_softmax(softmax_topi)
print(tvm.lower(sst, [tarray], simple_mode=True))
输出结果：

}
}
}
}
融合卷积
可将 topi.nn.conv2d 和 topi.nn.relu 融合在一起。
备注
TOPI 函数都是通用函数，不同的后端实现性能优化的方式不同。所有的后端都必须在 compute 声明和 schedule 范围内调用它们。 TVM 会选择调用目标信息的正确函数。
data = te.placeholder((1, 3, 224, 224))
kernel = te.placeholder((10, 3, 5, 5))
with tvm.target.Target("cuda"):
conv = topi.cuda.conv2d_nchw(data, kernel, 1, 2, 1)
out = topi.nn.relu(conv)
sconv = topi.cuda.schedule_conv2d_nchw([out])
print(tvm.lower(sconv, [data, kernel], simple_mode=True))
