Mask_rcnn: Cannot run demo.ipynb: ImportError: libgthread-2.0.so.0: cannot open shared object file: No such file or directory

Hi,

I'm using Docker to manage the code environment. If you can help me to make it work, I'll be glad to release the image so that anyone can easily run the code without any installation issue. My Dockerfile is

FROM tensorflow/tensorflow:latest-py3-jupyter

ADD Mask_RCNN/ /Mask_RCNN/

ADD startup.sh /

RUN apt-get -y update

WORKDIR /

RUN pip3 install -r /Mask_RCNN/requirements.txt

RUN cd /Mask_RCNN/ && python3 setup.py install

CMD /startup.sh

where startup.sh is simply

/bin/bash -c "jupyter notebook --ip 0.0.0.0 --allow-root --no-browser --NotebookApp.token='foobar'"

I build my image without major complaints: the only weird messages are

Step 8/9 : RUN cd /Mask_RCNN/ && python3 setup.py install
 ---> Running in 97e37d7ca56e
WARNING:root:Fail load requirements file, so using default ones.
[...]
zip_safe flag not set; analyzing archive contents...

Other than that, the build process seems fine. Then I run the container, which simply starts a Jupyter notebook, and I launch demo.ipynb: the first cell gives me this error

I don't understand what's happening, could you please help me? Thanks in advance.

Never mind the reason.

The solution is use apt-get update and then apt-get install install libgtk2.0-dev.

Just enjoy it.

Thanks!
