OSError: cannot identify image file

[JingyiHu]

I have this issue when I try to use prepare_data function. I already have the newest version of pillow. 
I also noticed that the tiff files that I get from the "export training data for deep learning" can not be opened . 
(constantly showing this)
 
As fopr the meta data format, I tried labeled tiles, classified tiles, KITTI labels and PASCAL VOC format. None of their output tiff can be opened.

I m wondering how can I fix this? Thank you!

This error persists when the raster is not multi-spectral.  16-bit does not appear to be supported.  And when changing the raster to 8-bit, it does not appear to support RGB rasters.  I have been having many of the issues reported with the deep learning toolset, and any support would be appreciated. Below is an error from the python API when trying to view the labeled objects. 

All the exported .tiff images (I have also tried .png with the same issue) are black squares. They should look something like this:
