_mask.so : undefined symbol: _Py_ZeroStruct #90

Closed leekyungmoon closed 10 months ago

leekyungmoon commented 6 years ago

After running the command 'make' under 'coco/PythonAPI', I tried running the script to create my own dataset using cocoAPI.

When running my script, I got an error : "pycocotools/_mask.so: undefined symbol: _Py_ZeroStruct" in Ubuntu 16.04.

I'll appreciate it if you could help me, thanks.

Cause of the Python version. If you use Python2.7, in PythonAPI/ floder, do: sudo make python setup.py build_ext install If you are using Python3, you need to modify the Makefile to change every 'python' to 'python3' and do: sudo make python3 setup.py build_ext install

wish you pass

@FumingX Thanks, it worked.

rishi8313 commented 6 years ago

What if I don't have sudo permissions.

salihkaragoz commented 6 years ago

@rishi8313 You can install on user' local with

pip install --user pycocotools

rishi8313 commented 6 years ago

Thanks a lot.. It worked..

hello, I installed it on my user local with pip install --user pycocotools

but I still have error with ImportError: /home/max/Downloads/MTCNN/models/research/pycocotools/_mask.so: undefined symbol: _Py_ZeroStruct

Did you have any luck with this issue? I am having the same problem... @Maxwell2016LeChouchou

@Maxwell2016LeChouchou I am having same problem too.

Maxwell2016LeChouchou commented 5 years ago

@JanithT-Lboro @Harshad1409 Hello guys, use coco rather than cocoapi and i have solved the question by using follow command lines: 1st step: git clone https://github.com/pdollar/coco.git

2nd step: cd coco/PythonAPI sudo python3 setup.py build_ext --inplace

3rd step: sudo python3 setup.py build_ext install

4th step is to go back home directory by cd ~ and excute the following lines to see if your installation succeed or not: python3 import pycocotools

Hopefully this helps

I work with cython and had the same problem, the solution worked for me - thanks!

Hi. my problem not solved yet! please help me I am confused.

every time I run this command: https://github.com/tensorflow/models/blob/master/research/object_detection/legacy/eval.py

this error appear:

what should I do??

Also looking for assistance. I've followed all recommendations successfully, but it still hasn't resolved the issue.

I've successfully compiled, installed, etc for python and python3 but it hasn't made a difference in the above error.

I changed python to python3 (in /Mask_RCNN/samples/coco/PythonAPI/make) and make again...Problem solved.
