[Bug] Cannot find function tvm.contrib.cudnn.conv2d.forward

[wangzy0327]

Expected behavior

I want to using cudnn libraies in relay

Actual behavior

I recompiled tvm with USE_CUDNN config successfully

Environment

OS :Ubuntu 18.04
TVM:0.9

Steps to reproduce

I refer to the example to run code.

I get the following error.

Traceback (most recent call last):

  Check failed: (f != nullptr) is false: Cannot find function tvm.contrib.cudnn.conv2d.forward in the imported modules or global registry. If this involves ops from a contrib library like cuDNN, ensure TVM was built with the relevant library.

how to solve the problem?
