[Apache TVM Discuss] [Questions] Do we have to identify tvm.nd.array context?


for example, if we use `ctx=cuda`,

both input datas are run correctly.

I saw that default tvm.nd.array context is cpu(0),
>input =  tvm.nd.array(shape)


but, I designate context "cuda"
> input = tvm.nd.array(shape, ctx)

both inputs are run correctly, but it have small performance diffs.

**Can we get better perfs with designated context like second one?**

I want to know about principle of tvm data context
