Hey! What size of image you use from gym torcs?

[Lukeeeeee]

The image given by torcs env only supported 64 64 3, as I know, also mentioned in this issue:

https://github.com/ugo-nama-kun/gym_torcs/issues/2.

And this size, I believe, is too small to train a deep neural network.

So If there any way I can extract a higher resolution image from gym torcs? Or how did you solve this problem? Thanks!

We use an image size of 256x192, we solved the problem by compressing the image before passing to Python

But the original image is only 64x64. U mean reshape the 64x64 image to 256x192 image?

No, we are using modified torcs, original image is 256x192 as set in the options. It described in readme.

So is there any tutorial about how to use this modified gym torcs? And does it support higher resolution rather than 256x192? Thanks!

when I use the interface:obs_vision_to_image_rgb_proto(),there are actually some buffer data.However,I just use: cv2.imdecode(image_jpeg, cv2.CV_LOAD_IMAGE_COLOR),the value of image data becomes zeros totally. Have you ever encountered similar problems? Looking forward your respond.Thank you! @skariel @s271
