检出 assert_array_equal

对于浮点数组的相等性测试可能会失败，并且assert_almost_equal更可靠.

for floating point arrays equality test might fail and assert_almost_equal is more reliable.

更新

一些版本以前numpy获得了assert_allclose，现在它是我的最爱，因为它允许我们指定绝对误差和相对误差，并且不需要十进制舍入作为接近度标准.

A few versions ago numpy obtained assert_allclose which is now my favorite since it allows us to specify both absolute and relative error and doesn't require decimal rounding as the closeness criterion.
