can't import `arraymancer_vision`

[terasakisatoshi]

Hi, I would like to your module but can't import

here is the code I tested

#sample.nim
import arraymancer_vision
echo "hello"

and here is an error log

$ nim c sample.nim

Hello @terasakisatoshi,

Unfortunately Arraymancer Vision has not been updated following changes in Arraymancer 0.3.0 and 0.4.0.

I do plan to at least add image reading in the main repo, do you have any other needs?

[mratsim]

I've added reading from and writing to images: https://github.com/mratsim/Arraymancer/pull/244.

[terasakisatoshi]

Thank you for your modification. I have confirmed I can read image via arraymancer :

import arraymancer
var origimage=read_image("nim.png")
echo origimage.shape # [4, 900, 1187]
origimage.write_png("output_from_nim.png")

I do plan to at least add image reading in the main repo, do you have any other needs? For now, reading or output image feature is enough for me. If you find the time, It is appreciated to add feature that it visualizes image.

[mratsim]

For the visualisation I think that should be added as an external library.

You can check nim-plotly and here is an example of using nim-plotly with arraymancer: NeuralNetworkLiveDemo

Thank you for your information!!! This is cool! I will try it.
