Error: expected primary-expression before ‘float’ frpm auction_match_gpu.cpp

[GabbySuwichaya]

I run the following line,

python eval.py --gpu 0 --resume logs/punet_baseline/punet_epoch_99.pth

Then, I received the following error

I had the same issue.
I changed all the 'data_ptr' into 'data' in the '/mnt/HDD4TB3/PU-Net_pytorch/auction_match/auction_match_gpu.cpp' file and it worked.

I had the same issue. I changed all the 'data_ptr' into 'data' in the '/mnt/HDD4TB3/PU-Net_pytorch/auction_match/auction_match_gpu.cpp' file and it worked.

I just made this changed and it solved the ImportError: No module named 'am' problem as well.
Thank you @ZhuXiyue !
