TypeError: only integer scalar arrays can be converted to a scalar index

Part 1 (2017)

This is a new kind of error throwing while using the plots function. Here’s the traceback

---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

----> 1 plots(img=img, titles=labels)

/home/ai/Project/IPI_old/IPI_DL/plots.py in plots(img, figsize, rows, interpolation, titles)
     13 def plots(img, figsize=(12,6), rows = 1, interpolation = False, titles = None):
     14     if type(img[0]) is np.ndarray:
---> 15         img = np.array(img).astype(np.uint8)
     16         if (img.shape[-1] != 3):
     17             img = img.transpose((0,2,3,1))

TypeError: only integer scalar arrays can be converted to a scalar index

Any ideas why its happening ?

Hi @WaterRocket8236, did you get sorted on this? I am experiencing the same error in the new part 1 when loading images in the first notebook, in the local function load_img_id
