Test error on SpatialPyramidPooling and fail on SpatialSameResponseNormalization

[lim0606]

Hi, this is Jaehyun Lim.

I installed the recent version of inn (4c2dc1c), and I tried to run test/test_jacobian.lua.

I got following messages;

1/4 ROIPooling .......................................................... [PASS]
2/4 SpatialPyramidPooling ............................................... [ERROR]
3/4 SpatialStochasticPooling ............................................ [PASS]
4/4 SpatialSameResponseNormalization .................................... [FAIL]

Is there anyone who can help me to solve this problem? :)

Thanks

hi, can't reproduce the error in SPP. The error in same map normalization is due to its high nonlinearity. Both modules are just containers for nn modules and safe to use

@szagoruyko

Thank you for response!

Then, it might be the problem of the configuration of torch in my system.

I will figure it out. Thank you again :)

Best regards,

I reinstalled torch and solved the error in SPP.

However, the error for SpatialSameResponseNormalization is not resolved. I will just leave in this way for a while.

Anyway, thank you for your comment!
