I am running old code using scipy 1.3.1 with the following import:

from scipy.misc import bytescale
with the following error:
ImportError: cannot import name 'bytescale'
I see that bytescale has been removed since 1.3 (source). The thread suggests that the scikit-image util module would be a good replacement, but does not offer one. 
What is a good alternative to the now deprecated scipy.misc.bytescale()? 
I think there is no direct equivalent (be able to specify high and low) but you can use things like skimage.util.img_as_ubyte for scaling  between 0 and 255, skimage.util.img_as_uint for scaling  between 0 and 65535. Check them here: https://scikit-image.org/docs/stable/api/skimage.util.html (The img_as_* stuffs)
skimage.util.img_as_ubyte is a replacement for scipy.misc.bytescale
the scipy.misc.bytescale doc states the following:
  
Byte scaling means converting the input image to uint8 dtype and
  scaling the range to (low, high) (default 0-255). If the input image
  already has dtype uint8, no scaling is done.
the skimage.util.img_as_ubyte doc states the following:
  
Convert an image to 8-bit unsigned integer format. Negative input
  values will be clipped. Positive values are scaled between 0 and 255.
