fopen squeezenet_ssd_voc.param failed

[joeyprofile]

Hi,

I build NCNN and run it on Ubuntu20.04:
mkdir build
cd build
cmake -DCMAKE_BUILD_TYPE=Release -DNCNN_VULKAN=ON -DNCNN_BUILD_EXAMPLES=ON ..
make

When i run "/ncnn/build/examples$ ./squeezenetssd ../../images/256-ncnn.png", it would hit this error:
fopen squeezenet_ssd_voc.param failed.
When run "./benchncnn 64 2 0 0 1", it hit "Floating point exception (core dumped)":
./benchncnn 64 2 0 0 1
Enumerating devices...
Connecting to device: 0(128)
Floating point exception (core dumped).

Regards,
Joey
