no module named 'chainercv.datasets'

[dojinkimm]

Hi I am currently using example from this repo chainercv/examples/faster_rcnn/demo.py I have installed chainer 6.1.0 and chainercv 0.13.1

When I run this code following error occurs ModuleNotFoundError: No module named 'chainercv.datasets'; 'chainercv' is not a package

I found that datasets are in chainer but I still could not find voc_bbox_label_names, FasterRCNNVGG16, vis_bbox

how can I fix it?

can you paste result of pip freeze | grep chainercv? if there is no output, chainercv is not installed so you need to install chainercv with command pip install chainercv (if you want to install in your system, you need sudo).

chainercv is installed its version is 0.13.1

There is chainer.datasets but no voc_bbox_label_names or fasterRCNNVGG16

[knorth55]

voc_bbox_label_names is in chainercv.datasets not chainer.datasets. FasterRCNNVGG16 is also in chainercv.links.

Yes I just wondered because I could not find chainercv.datasets and chainercv.links

This is the error that I receive. I did not mention above but I am using Mac OS X and I realized that it is not officially supported OS. Is this a reason for this error?

Please reinstall chainercv.

sudo pip uninstall chainercv
sudo pip install chainercv
python -c "import chainercv"
