/usr/local/caffe2_build/include/caffe2/utils/math.h:36:22: fatal error: Eigen/Core: No such file or directory

I tried to install DetectAndTrack from source, but failed, thus I turned to Dockerfile, and successfully installed caffe2 and DetectAndTrack. All the test passed until I the train module:python launch.py -c configs/video/2d_best/01_R101_best_hungarian.yaml -m train, and it saysAttributeError: Method AffineChannelNd is not a registered operator. Did you mean: [AffineChannel]. I investigated this problem and found that the lib/ops/affine_channel_nd_op.* need to be copied to caffe2/modules/detectron/. However, there is no detectron folder under the caffe2 installed by dockerfile, and then I git clone the detectron to the caffe2 folder. After I copy all the affine_channel_nd_op.* into the /detectron/ops/, and make, it occurred the error:/usr/local/caffe2_build/include/caffe2/utils/math.h:36:22: fatal error: Eigen/Core: No such file or directory. I found several solution for this error, but all of them need to revise the .cc files, for example, caffe2/core/context.cc file. But there is no such files in caffe2 using Dockerfile. How to deal with this problem?
