got different output from sample when using pretrained model

[notasadsong]

Hi! I am trying to use the pretrained models to process images from KITTI Odometry and changed nothing of the code. But I got some invalid segmentations. Then I tested in the sample image4 in here .The output is as follow:

The config is: python3 -u mseg_semantic/tool/universal_demo.py --config=mseg_semantic/config/test/default_config_360_ms.yaml model_name mseg-3m model_path mseg-3m.pth input_file dirtroad10.jpg

Could you please tell me where the problem is? Thanks!

Hi, I recommend cloning the Colab notebook again and re-running it. I just re-ran it in Colab and my result looks very different from yours. Did you make changes to the notebook?

[notasadsong]

I just cloned the github code again and ran it with the command in Colab notebook. I'm sure I haven't change anything but I got really different results. The grayscale image is as follow, without any segmentation: Maybe there is someting wrong with it?

Hi @notasadsong, could you please post screenshots and copy the text output of all of the cells here, from the Colab session you are running? (from a fresh copy of the Colab)?

Hi @johnwlambert, I didn't run the code in the Colab. Instead I ran it in the command window. I got the text output as follow:

I see. If you run it in Colab, what is the result you see? Can you quickly open up this Colab link, run all the cells (will take no more than 5 min), and share your Colab result here?

If you can copy the lines verbatim from the Colab to a bash script on your local machine, the result should be identical : - ) If not, can you please share your OS, python versions, versions of every library from here: https://github.com/mseg-dataset/mseg-semantic/blob/master/requirements.txt#L1, the exact commands you are running, and the bash script you are using to execute this?

[notasadsong]

I ran it in Colab and I got the expected result which looks so great. Still I didn't see identical result when I ran it on local machine. I use ubuntu18.04, python3.9.7, and the version of the libraries(only contains the libraries with version infomation) are as follow:

hydra-core==1.1.1 opencv-python==4.5.5.62 pandas==1.3.4 Pillow==8.4.0 PyYAML==6.0 sklearn==0.0 torch==1.10.2
