Question about the psroi_pooling.so

[feitiandemiaomi]

Hi, Thank you for your amazing work
According to the guide ,When I run the demo,I meet an issue following:
gpu2@gpu2-PowerEdge-R730:~/OWFO/TF_Deformable_Net$ python ./faster_rcnn/demo.py --model mypath

And the other operating ,such training and testing,the same error as above, I see your description about installation ,I wonder if I need do more about installation ,especially about the psroi_pooling

Which version of gcc do you use? Maybe you should check make.sh and uncomment out lines for gcc5.

[feitiandemiaomi]

gcc 5.4 Let me try it ,Thank you a lot

[feitiandemiaomi]

I replace the newest make.sh and uncomment the code anout gcc-5 , it indeed does work,which solve the question of psroi_pooling.so and roi_pooling_layer.so ,but when it comes to the last , deform_conv_layer, it show the error.

I also check the code of gcc5-built of deform_conv_layer in make.sh , do not find the problem

@feitiandemiaomi Sorry I have no idea what's going on on your side, others came across this issue and reinstall gcc4 and solved, or merely through add this flag. Unfortunately I have no environment right now for me to test it on gcc5.

[Zardinality]

@feitiandemiaomi Hi, have you worked out where the problem is? I have updated readme to include a workaround given by others in another issue, which solves a very similiar problem.

[feitiandemiaomi]

Thank you a lot, I was worrying about it, Yesterday, I try modifying the make.sh and compiled ,but there were still some errors.

[dasing]

I also have this error. I have followed all of the instructions in the readme, but my psroi_pooling.so always have undefined symbol.
After searching for other information, I add this flag
-L $TF_LIB -ltensorflow_framework
to the end of the g++, then the generated .so file can be load successfully.
