easyFlyTracker command not executing

[peregrin-nook]

When I attempt to run the easyFlyTracker command (I am on Windows 11 using VSCodium), it responds with the message, "easyFlyTracker : The term 'easyFlyTracker' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:1

• easyFlyTracker

• 
  + CategoryInfo          : ObjectNotFound: (easyFlyTracker:String) [], CommandNotFoundException
  + FullyQualifiedErrorId : CommandNotFoundException"

And when I attempt to run it using "py -m easyFlyTracker" it respond with "No module named easyFlyTracker.main; 'easyFlyTracker' is a package and cannot be directly executed". Please help!

hi, update easyFlyTracker to new version(0.12.2) :

pip install --upgrade -i https://pypi.org/simple/ easyFlyTracker

then you can use this method to run easyFlyTracker:

python -m easyFlyTracker [config_path]      # Corresponding terminal command: easyFlyTracker [config_path]
python -m easyFlyTracker -a [config_path]   # Corresponding terminal command: easyFlyTracker_analysis [config_path]
python -m easyFlyTracker -c [config_path]   # Corresponding terminal command: easyFlyTracker_cam_calibration [config_path]

thanks. good luck.

Thank you, it works well! However, I have one more problem. After tracking the flies, I am unable to use "easyFlyTracker_analysis", and I get the message "no module named easyFlyTracker_analysis". Do I need to download easyFlyTracker_analysis separately? I can't find it in my designated folder for packages.

[azzhu]

if you want use "easyFlyTracker_analysis", you can:

python -m easyFlyTracker -a [config_path]

notice: "easyFlyTracker", but not "easyflytracker"

I was all done tracking my data, but when I finally analyzed it, I got this message:

What does this mean? I could analyze the demo files perfectly fine, but when analyzing my own files, which I had already tracked, I could not analyze them. Is there a solution to this problem?

[azzhu]

can you share your video file, config file and group file to me? I test it in my computer.

[peregrin-nook]

Sure, this is the link. I included the config.pkl file, as well. https://drive.google.com/drive/folders/13yIa48j8shN0Naso3ra4wOiGqJeIZ89m?usp=share_link

[azzhu]

Hi, I find two problems:

1, the "config.bmp" image in output path is incorrect, the circle is not drawn on the roi. which means the subsequent tracking is wrong. I suggest you double check that this step is configured correctly.

2, the fruit flies in the video do not move. the software cannot detect stationary objects. stationary objects are filtered out as background. the image in "output_path/.cache/background_image.bmp" proves it.

Thank you for the notice, I'll have to deal with these problems. I should be fine after resolving the problems, so thank you!
