Mask_rcnn: undefined symbol: _Py_ZeroStruct

[LifeBeyondExpectations]

I am not sure. This problem is on my computer or the code.

After I run the code below,
python3 coco.py train --dataset=/media/coco --model=coco

Errors come up.

Traceback (most recent call last):
File "/usr/local/lib/python2.7/dist-packages/numpy/core/__init__.py", line 16, in
from . import multiarray
ImportError: /usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct

During handling of the above exception, another exception occurred:

ImportError:
Importing the multiarray numpy extension module failed. Most likely you are trying to import a failed build of numpy. If you're working with a numpy git repo, try git clean -xdf (removes all
files not under version control). Otherwise reinstall numpy.

Original error was: /usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct

[waleedka]

The error is an import error. And the message says "Most likely you are trying to import a failed build of numpy.". So I would guess it's not an error in the code.

Also, please note that this model is built and tested on Python 3.5. You might need to make a few changes to run it on 2.7.

can you solve this problem?

edit the Makefile located in coco/PythonAPI/:
original:

#

all:
# install pycocotools locally
python setup.py build_ext --inplace
rm -rf build

install:
# install pycocotools to the Python site-packages
python setup.py build_ext install
rm -rf build

#

modified:

#

all:
# install pycocotools locally
python setup.py build_ext --inplace
rm -rf buildi
python3 setup.py build_ext --inplace

install:
# install pycocotools to the Python site-packages
python setup.py build_ext install
rm -rf build
python3 setup.py build_ext install
rm -rf build

#

All in all, add python3.
