image_data_float always returns an empty image (i.e. list composed of [0.0])

[rallen10]

This seems to be a persistent, unaddressed problem based on other issues dating back more than a year (#2089, #2169, #2665, #1840). The only difference for me is that 1. I am running in Unity, and 2. the image is always empty, therefore the workaround to discard image and grab the next one if it is empty doesn't work for me.

To reproduce:

import airsim
import numpy as np
client = airsim.MultirotorClient(timeout_value = 7200)
client.confirmConnection()
while True:
        response = client.simGetImages([airsim.ImageRequest("1", airsim.ImageType.DepthPerspective, pixels_as_float=True, compress=False)])[0]
        img1d = np.array(response.image_data_float, dtype=np.float)
        if len(img1d) != response.height * response.width:
            print('empty or bad image. Retrying...')
        else:
            print('properly formatted image!')
            break

I found pull request #2812 from a similar issue: #2811. I tried merging the pull request locally and rebuilding AirSim and the Unity wrapper, but to no effect. Still getting the same problem with an empty image

Same problem in Unity

I encountered the same problem in Unity, did you solve it?

I also used unity to develop, and found the same problem as yours in the latest airsim version. Have you finally solved it

@SworterW @weigangwen @chanho-code @rallen10 I am also facing the same issue (using Unity), were you able to solve this issue?

[rallen10]

Sorry I haven't looked at this work in years. Honestly can't remember if I found a solution, a workaround, or just abandoned this part of my project all together.

Not very helpful, I know, but figured I shouldn't leave you all hanging

@rallen10 Thanks for your reply! Are you able to share the github repo of your project?
