Hello! I would like to ask a question about darknet. The version of TVM is
v0.9.dev0. When I run the following code, I get a "kernel died" error.
```python
from tvm.relay.testing.darknet import __darknetffi__
from cffi import FFI
lib_path = "/home/zhangmengbo/tvm/Lsw/tvmtest/deploy_detection/libdarknet2.0.so"
cfg_path = "/home/zhangmengbo/tvm/Lsw/tvmtest/deploy_detection/yolov3-tiny.cfg"
weights_path =
"/home/zhangmengbo/tvm/Lsw/tvmtest/deploy_detection/yolov3-tiny.weights"
C = __darknetffi__.dlopen(lib_path) # Success
arg = C.load_network(cfg_path.encode("utf-8"), weights_path.encode("utf-8"), 0)
# Kernel died
```
The output of Jupyter is as follows. This problem has been bothering me for a
long time and I would appreciate very much if someone solved it. :sob:
