Problem with the functions (eg. Subtract/ Ratio)

[kousikkun]

I am unable to use the the basic functions for some reason on Ipython. - I already did "from flika import *" . Its giving 'ratio' 'subtract' as undefined. I am not sure if I am missing something. Thanks!

Hi @kousikkun, if you launch from within IPython, you need to also run import flika and then use the long name of the function. For subtract and ratio, these are flika.process.subtract and flika.process.ratio. The short names only work if you launch flika from a non-IPython terminal and you open the Script Editor. If you'd still like to use the shortened names, you can run in IPython:

from flika.process import *
generate_random_image()
gaussian_blur(sigma=2)

For instance, I followed these steps and was able to use ratio().

• Open a terminal on my Mac (Ventura 13.5.1).
• Clean install of python using a new venv (Python 3.11.7)
• Clean install of flika using and pip install flika
• Launch of IPython using ipython command in the terminal
• Launch of flika using from flika import *; start_flika()
• Importing flika using from flika.process import *
• Generate a random image using generate_random_image(500, 20)
• Applying the ratio function using ratio(0, 100, 'average', 0, True)
