do not rotate the video during Sklearn Visualization

[chongtianyifa]

Hi,

Thank you for the wonderful tool for behavior analysis. In my case, the mice were head-fixed. Therefore, the best way to visualize the result is to keep the view angle. However, it seems that the video was rotated 90 degrees anticlockwise.

Is there a way to keep the view angle in the Sklearn Visualization step?
Meanwhile, I found that the font is too small or blurry to discern sometimes. It would be better if we can set the font size.

Thanks,
Lei

Hi @chongtianyifa! Someone else just pointed this out. If you update SimBA with pip install simba-uw-tf-dev --upgrade, you should see the checkbox with red underline in the screengrab in image linked below. To not rotate the video, leave this checkbox unchecked before creating video.

The thickness of the font is too high for your resolution which makes it blurry, it is hard coded to 2 and can't currently be set in the GUI, but if you wait a few days I will make option available.. If you want to change it before, it's the final 2 in e.g., this line of code, maybe change it to a 1.

simba/simba/sklearn_plot_scripts/plot_sklearn_results_all.py

Line 144 in 2f1a4c9

cv2.putText(self.frame, str('Ensemble prediction'), (10, (self.video_meta_data['height'] - self.video_meta_data['height']) + self.spacing_scale * self.add_spacer), self.font, self.font_scale, (0, 255, 0), 2)

Hi,

Thank you for the quick response. I cannot use the upgrade solution as I failed many times to install the tensor flow version. I am using simba-uw-no-tf.

I did not see plot_sklearn_results_all.py function here. Which one should I modify?

Hi @chongtianyifa - I have not maintained simba-uw-no-tf for some years, would you mind switching to pip install simba-uw-tf-dev? You could do pip uninstall simba-uw-no-tf followed by pip install simba-uw-tf-dev and you should be able to open your project as normal but let me know if not.

I still couldn't install the tf-dev version. Here is how I install it:

1. create a new virtual environment conda create --name simba-tf python=3.6 and activate it.
2. pip install simba-uw-tf-dev
3. after call 'simba', error came out
   
4. then pip uninstall shapely and conda install -c conda-forge shapely. It failed:

Hi, I actually tried pip uninstall shapely and then pip install shapely. It worked! Now I see the choice not to rotate the video. Thank you!
