Thank you so much in advance!

I got the same bug. Do you get the reasons? Thank you for telling me, if you have the solve method.

I solve the problem by CHANGE: temp = denoise_tv_bregman((im - min_img) / (max_img - min_img), weight = config["TV_DENOISE_WEIGHT"]) TO: temp = denoise_tv_bregman(np.float64((im - min_img) / (max_img - min_img)), weight = config["TV_DENOISE_WEIGHT"])
