where is the *_result.npz file

[linchunmian]

Hi, thanks for your work.
When I run demo.py, it occurs the error message 'no 000821_result.npz file'. I follow your instruction to prepare the dataset and pretrained model, but I really don't find the result file.
Please help me!
Thanks in advance.

For your issue, you may need to check the run_demo.sh file to see the directory of the *_result.npz and make sure it is already generated there.

Thanks for reply. Do I need to run demo.py under inference option to geenrate the result.npz file?
Also, If I directly use the extracted feature that you provide, does it mean that I don't need to install mmdetection?

Right, you can find that the feature extraction and inference are two separate stages in the run_demo.sh, which just calls the demo.py. So if you use the extracted feature, you don't need to install mmdetection, and just run the demo.py to generate the result file and visualize it.

Thanks. Another problem I consider, if I want to train my own dataset, how should I do? Also, I am quite confused that how to use conda to install mmdetection and py37 virtual env simultaneously?
I am sorry I don't get your means and commonly we just create an env to install required packages for the certain project, is it?
Many thanks and looking forward to receiving your help!

To train your own dataset, you may need to write your customized DataLoader class. You can refer to /src/DataLoader.py.
Conda can be used to setup any number of virtual envs as long as their names are different, i..e,:

conda create -n py37 python=3.7
conda activate py37
# Then the libs installed by pip are within the py37 env.

conda create -n mmdetection python=3.7
conda activate mmdetection
# Then the libs installed by pip are within the mmdetection env.

This good separation between different envs within the same OS system is exactly why we want to use conda/anaconda. Isn't it?

Thanks. Maybe I get your idea. You mean, I could extract data feature in mmdetection env, and perform model inference and visualize in py37 and pytorch1.0 env, is it?

Not exactly, mmdetection env is only for object detection in my code. Feature extraction, inference, and visualization are all done within py37 env. For convenience, I put all of these together in demo.py. You’d better to check the run_demo.sh, these are not hard to understand.

Many thanks, and I would further check the code you mentioned.

I want to run the demo.py for feature extraction, inference, and visualization. So, I didn't create the mmlab environment. However, when I run the demo.py file it is showed me "No module named "mmdet". So I pip installed mmdet. Then it was showing "AttributeError: module 'mmcv' has no attribute 'version'
So, I was trying to pip install mmcv-full. But it is showing " failed to build mmcv-full". How can I solve?

@monjurulkarim Thanks for your interest in this work!
If you need to run demo.py for feature extraction, the mmdetection env mmlab is required. Recently I noticed that official mmdetection and mmcv-full are newer than what I used in this repo. So, to install mmlab env, you need to install mmcv-full==1.1.1, and checkout the tag v1.1.0 for mmdetection source code. You can refer to the following steps, which are also updated to the instructions in the README:

# create python environment
conda create -n mmlab python=3.7

# activate environment
conda activate mmlab

# install dependencies
pip install torch==1.4.0+cu100 torchvision==0.5.0+cu100 -f https://download.pytorch.org/whl/torch_stable.html
pip install mmcv-full==1.1.1

# Follow the mmdetection installation instructions
git clone https://github.com/open-mmlab/mmdetection.git
cd mmdetection
git checkout v1.1.0  # important!
cp -r ../Cascade\ R-CNN/* ./  # copy the downloaded files into mmdetection folder

# compile & install
pip install -v -e .
python setup.py install

Thank you for your help.
I have followed your instruction. Now I am getting the following error:

Do have idea why this is happening?
Thanks

It seems that your installed torch-scatter is not compatible with the other torch libs. You can type pip list | grep torch in py37 env, and see if these libs are correct:

torch                 1.2.0                
torch-cluster         1.4.5                
torch-geometric       1.3.2                
torch-scatter         1.4.0                
torch-sparse          0.4.3                
torchstat             0.0.7                
torchsummaryX         1.3.0                
torchvision           0.4.0a0+6b959ee

Thanks for your quick response.
My torch list are these:

Is this a problem?
