Maskrcnn-benchmark: No module named maskrcnn_benchmark.config

❓ Questions and Help

Hi
I have followed the instructions to install this package. However, when I run the notebook demo under './demo', it gives an error:

ImportError: No module named maskrcnn_benchmark.config.

[Kongsea]

Use python 3.x.

@Kongsea
I've got the same ERROR message, but I'm using python 3.6.6

$ python --version
Python 3.6.6

Any other suggestions?

@jiapei100 I found the solution. You need to create an empty __init__.py under the folder "maskrcnn_benchmark".

I am adding support for Python 2 in https://github.com/facebookresearch/maskrcnn-benchmark/pull/11 and it should fix the errors you are seeing.

I'll verify that the training that I launched yesterday matches the excepted accuracies and I'll merge it

[fmassa]

For info, I've just merged https://github.com/facebookresearch/maskrcnn-benchmark/pull/11 , so the codebase should work with Python 2 as well.

[fmassa]

Let me know if you still face problems after pulling from latest version of maskrcnn-benchmark

[hitchhooker]

this is caused by not using conda. after creating new conda name you need to always use source activate name_u_gave to not get this error.

conda create --name maskrcnn_benchmark
source activate maskrcnn_benchmark

[fmassa]

yes, I've improved the documentation to add the source activate maskrcnn_benchmark after creating the environemnt

[jiapei100]

@fmassa
Nope... I didn't use conda at all....

@yaoliUoA
I've added __init__.py under the folder maskrcnn_benchmark, but the ERROR continues....

[fmassa]

Make sure that the installation wmis done properly
Also, pull from latest master, I've fixed the missing __init__.py files

As a note, having conda is a very easy and simple way of managing several python environments, and I'd highly recommend it.

[moyans]

when i use 3.x python with conda, every thing is all right.

[Kongsea]

@moyans me too.

[fmassa]

We now support python2 as well, so if it wasn't working before with Python 2, now it should be.

I had the same issue, trying this link helped: https://github.com/jupyter/notebook/issues/1524
