URL: https://github.com/apache/tvm/issues/7301
**Reprocuce code:**
`cd ${TVM_HOME} && python vta/tutorials/frontend/legacy/deploy_detection.py`
**description:**
I am using the [newest version code on 'Fri Jan 15 07:59:28
2021'](https://github.com/apache/tvm/tree/c9474639dd3761b78a457ab274603d87a3dcf9b8)
with pynq Z1 board. Error occurs inside `graph_pack()` when running
yolo-v3-tiny in deploy_detection.py.
```

I've add more shape info in `src/relay/op/tensor/transform.cc` as follows:

**problem:**
**A relay IR is trying to reshape source tensor with shape `1, 1, 16, 16,
26, 26]` in to shape [1, 255, 26, 26] while the high demision is 16*16=256.
I've tried to find the error op, it seems the %162-th op in compiled module
has output shape of (1, 255, 26, 26), The error problem is why it's shape is
transformed into 256 at previous stages?** Hoping programers knowing vta or
relay could offer some help， thanks a lot!

**related changes:**
after some searching, this is some related issues i’ve found.
@fprotopapa had fixed another issue #7059 in `pack_dict` configure, change
the cast inedx from 185 to 186. 👍 Did your `deploy_detection.py` run
successfully after this change? looking forward to your practice, many thanks!
@huajsj had add the yolo-v3-tiny support in[ this commit
](https://github.com/apache/tvm/commit/09c55fd1f3354d2280bb792a252590ac6bd68e58)
some additional configs are:
I‘ve verified `deploy_detection.py` my macbook pro`Darwin Kernel Version
16.4.0:` and ubuntu linux server ` Ubuntu 18.04.2 LTS (GNU/Linux
5.4.0-58-generic x86_64)`, the same problem occurs.
