How to solve this problem?

[chenyuntc]

Are you using Python2? try add from __future__ import absolute_import arrary_tool is in utils/array_tool.py

ImportError: cannot import name array_tool I use python3!

I've just tried, it worked fine in my server with python 3.5.2...

python3 train.py train --env='fasterrcnn-caffe' --plot-every=100 --caffe-pretrain

Temporary fix: copy utils/array_tool.py to model/utils/ would fix for you. I will work on it to figure out why. see #12

or change it to from ..utils import array_tool as at

[chenyuntc]

I think you are using Python2, when I excute:

python2 train.py train --env='fasterrcnn-caffe' --plot-every=100 --caffe-pretrain

get the same error as you do:

Traceback (most recent call last):

    from utils import array_tool as at
ImportError: cannot import name array_tool

[chenyuntc]

sorry, I can't reproduce it. I've just tried demo.ipynb, It still works fine for me :sob:

Instead, when I changed it to pyhon2 kernel I get

maybe there is a break in python, I'll try to figure why.

@chenyuntc is 4gb gpu enough？

[chenyuntc]

Yes, usually it's around 3GB. But some times it will raise to 4 GB --- wired behaviour of CUPY.

hello,Have you solved this problem?I have same problem with python3.6..
