ImportError: cannot import name '_C' from 'fasterRCNN.lib.model' (/home/k/kajal/STTran/fasterRCNN/lib/model/__init__.py)

Please help

I guess you didn't compile the C++ code (correctly). Please run the setup.py.

Btw, I think the code only supports the cuda version<11.1.

Do you solve this problem? My cuda version is 11.8 and I also met this problem.

I think the exclusive solution is using cuda<=11.0 and GPU<2080Ti

[kajal15003]

I have downgraded the cuda version. But it is still showing the same error

[yrcong]

Have you compiled the code again after downgrading the cuda version?

[kajal15003]

Yes, it is showing the below one in the output running build_ext

我也遇到了这个问题，断断续续搞了三天进行了很多操作，不确定哪步起的作用，大概逻辑是：

1. 作者提供了fasterRCNN/lib/build文件，里面明明有我们要的‘_C’文件，并且报错中的fasterRCNN/lib/model/里也有却找不到； 都说版本不对，我设置了很多搭配：成功的是CUDA10.0+pytorch1.1，由于我是Ubuntu22.04安装CUDA10.0相当费劲，经历了GCC降级等，最后我这边整成了多版本CUDA（因为之前别的程序使用高版本，我怕捡了芝麻丢了西瓜）
2. 改完版本以后能找到了，但是报错‘_C’文件里少东西，了解了一下是因为‘_C’文件是这个作者提供的，我们应该自己运行一下，于是我去到fasterRCNN/lib目录运行python setup.py build_ext --inplace，生成自己的‘_C’文件在对应位置，解决了就
