faster-rcnn.pytorch ImportError: cannot import name '

ImportError: cannot import name '_mask'

I use pytorch-1.0 and python3.6.7,and build under conda.the process of building did't show error.but,when start to train trainval.net,it shows the following error:

File "trainval_net.py", line 27, in from roi_data_layer.roidb import combined_roidb File "/home/ccyoung/workspace/faster-rcnn.pytorch/lib/roi_data_layer/roidb.py", line 9, in from datasets.factory import get_imdb File "/home/ccyoung/workspace/faster-rcnn.pytorch/lib/datasets/factory.py", line 15, in from datasets.coco import coco File "/home/ccyoung/workspace/faster-rcnn.pytorch/lib/datasets/coco.py", line 23, in from pycocotools.coco import COCO File "/home/ccyoung/workspace/faster-rcnn.pytorch/lib/pycocotools/coco.py", line 60, in from . import mask File "/home/ccyoung/workspace/faster-rcnn.pytorch/lib/pycocotools/mask.py", line 3, in from . import _mask ImportError: cannot import name '_mask'

it seems the building problem of coco API

make sure the branch is pytorch-1.0 and cd lib && python setup.py build develop then retry?

make sure the branch is pytorch-1.0 and cd lib && python setup.py build develop then retry? make sure. I clone it with --b

Having the same problem as well. I am using the pytorch-1.0 branch and has run "python setup.py build develop".

Just find out that you have to install the CoCO API.

cd data

git clone https://github.com/pdollar/coco.git cd coco/PythonAPI

make

cd ../../..

Just a side note. If which python does not refer to the python version that you use, you might want to modify the MakeFile. In my case, I need to change python to python3.6 in the MakeFile.

I tried and failed to get things working...

CoCO API is now at https://github.com/cocodataset/cocoapi

I am seeing the following error even after @JojoFisherman 's suggestions

progress, I fixed the stale COCO pytools

see: https://github.com/cocodataset/cocoapi/issues/59#issuecomment-469859646

Just find out that you have to install the CoCO API.

cd data

git clone https://github.com/pdollar/coco.git cd coco/PythonAPI

make

cd ../../..

Please @jwyang add into the readme for easy install.

我使用pytorch-1.0和python3.6.7，并在conda下进行构建。构建过程未显示错误。但是，当开始训练trainval.net时，它显示以下错误：

文件“trainval_net.py”，第27行，在从roi_data_layer.roidb进口combined_roidb 文件“/home/ccyoung/workspace/faster-rcnn.pytorch/lib/roi_data_layer/roidb.py”，9号线，在从datasets.factory进口get_imdb 文件“ /home/ccyoung/workspace/faster-rcnn.pytorch/lib/datasets/factory.py”，第15行，来自datasets.coco import coco 文件“ /home/ccyoung/workspace/faster-rcnn.pytorch/ pycocotools.coco中的“ lib / datasets / coco.py”行23，从中导入COCO 文件“ /home/ccyoung/workspace/faster-rcnn.pytorch/lib/pycocotools/coco.py”，行60 。从中导入遮罩文件“ /home/ccyoung/workspace/faster-rcnn.pytorch/lib/pycocotools/mask.py”，第3行。 ImportError：无法导入名称“ _mask”

似乎可可API的构建问题

请问您是怎么解决这个问题的

Just find out that you have to install the CoCO API.

cd data

git clone https://github.com/pdollar/coco.git cd coco/PythonAPI

make

cd ../../..

I am using Windows 10, how do i solve the problem ( from . import _mask ImportError: cannot import name '_mask' from 'pycocotools' ())

Please help.

I am sorry,i cannot understand "make" and"cd../../",Can you explain it in more detail?

I tried pip install pycocotools. And it worked

make sure the branch is pytorch-1.0 and cd lib && python setup.py build develop then retry?

Having the same problem as well. I am using the pytorch-1.0 branch and has run "python setup.py build develop".

Same issue here and I tried "pip install pycocotools" or "conda install". It worked

When I tried to make, got

error: command 'D:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Tools\MSVC\14.25.28610\bin\HostX86\x64\cl.exe' failed with exit status 2 make: *** [Makefile:3: all] Error 1

Dose anyone know what this means ?

After generating pycocotools directory('xxx/xxx/data/coco/PythonAPI/pycocotools'), replace the original pycocotools with this new one. The new pycocotools should include file.so like '_mask.cpython-36m-x86_64-linux-gnu.so'.
