Tif images show complete black

  • 772

I got datasets from Cell Tracking Challenge for deep learning task, but tif images (label images) are showing complete black. Geeqie, Gnome image viewer, and Shutter have been tried.

My configuration is:

Ubuntu 18.04
Nvidia Driver 430  
libtiff.so.5.3.0

tif image extracted form downloaded dataset

identify -verbose man_seg002.tif gives:
