 ### Installation 
+- Following configurations are tested
+    - Ubuntu 16.04 LTS
+    - Python 3.6 (Conda Environment has been used)
+    - Cuda 9.0
+    - GCC 5 (GCC 6 does not work)
+    - GPU Tesla K80
+
+- What will not work?
+    - I tried Python3.5, Python3.7 and Python2.7. None of these python versions worked for me.
+    - GCC 6 (On Debian, GCC 5 is not officially supported. So you may need to shift to Ubuntu. There will be workaround though that I didn't explore)
+
 
 1. Install PyTorch 0.4.1 and torchvision following the [official instructions](https://pytorch.org/).
