please use forward slashes (even on windows) and an absolute path for the filenames there

none of the above looks like a valid path to an image. what is "negative_images" ?

btw, "haartraining" is from outdated 2.4 ? and why the heck are you running this from an anaconda prompt ?

my image id of Bmp format , so at the end negative_images should be replaced with bmp

IF there is a .bmp extension, that MUST go into the filename, too.

(imho, we found the main problem !)

I have changed as .bmp , but though I'm getting the same error , what should be replaced instead of "haartraining" ?
