jasaw opened a new issue #20657:
URL: https://github.com/apache/incubator-mxnet/issues/20657
## Description
When `MXNET_CONF_PATH` is defined, `find_conf_path` in `libinfo.py` returns
a string rather than a list of strings, causing `tvmop.py` to fail.
### Error Message
>Traceback (most recent call last):
File "main.py", line 23, in <module>
import mxnet as mx
File "/storage/inference/python-mxnet/mxnet/__init__.py", line 103, in

with open(_CONF_TVM_OP[0], "r") as f:
IsADirectoryError: [Errno 21] Is a directory: '/'
## To Reproduce
### Steps to reproduce
1. `export MXNET_CONF_PATH=/some/path/to/tvmop.conf`
2. `import mxnet` in python
