change scipy.misc.imresize() to PIL.Image.resize()

[guplersaxanoid]

scipy.misc.imresize() was depreciated in SciPy 1.0.0, and was removed in 1.3.0.

I ran into the following error after applying this change.

Traceback (most recent call last):`
   File "C:\Users\chuzh\venv\lib\site-packages\PIL\Image.py", line 2645, in fromarray
     mode, rawmode = _fromarray_typemap[typekey]
KeyError: ((1, 1, 3), '<f4')

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File ".\train.py", line 210, in
    evaluate()
  File ".\train.py", line 192, in evaluate
    out_bicu = np.array(Image.fromarray(valid_lr_img[0]).resize((size[0] * 4, size[1] * 4), resample=Image.BICUBIC))
  File "C:\Users\chuzh\venv\lib\site-packages\PIL\Image.py", line 2647, in fromarray
    raise TypeError("Cannot handle this data type")
TypeError: Cannot handle this data type

Once I changed this line
out_bicu = np.array(Image.fromarray(valid_lr_img[0]).resize((size[0] * 4, size[1] * 4), resample=Image.BICUBIC))
to
out_bicu = np.array(Image.fromarray(((valid_lr_img[0] + 1)*127.5).astype(np.uint8)).resize((size[1] * 4, size[0] * 4), resample=Image.BICUBIC))
everything works correctly.

This is due to the fact that Image.fromarray( ) function only takes in numpy array whose elements are uint8 data type.
