ModuleNotFoundError

[wangx404]

Description

This is an error when running example/rcnn by bash sript/resnet_voc07.sh. It raises import error.

And there is also a similar problem happens.

Environment info (Required)

Ubuntu 17.10

Package used (Python/R/Scala/Julia):
(I'm using Python.)

Error Message:

1. 'ModuleNotFoundError: No module named 'rcnn.cython.bbox''.
2. 'ImportError: cannot import name '_mask''

What have you tried to solve it?

I copied some other files from previous modules, such as '_mask.c' and 'bbox.c' to the file folder.
And the problem was solved.
So what is wrong with this problem? Is there something wrong with my system?

I think you may need to install the cython pacakge in the RCNN folder https://github.com/apache/incubator-mxnet/tree/master/example/rcnn/rcnn/cython

3Q. I think this may be the reason. I have forgotten mxnet using C code to spped up.

To prevent this kind of issue from arising again, #11373 removed all cython completely.
