+Simple tests for verifying software requirements.
+These tests will check if the following conditions
+are met:
+
+    * Python is 3.0 or higher.
+    * TensorFlow is 1.4 or higher.
+    * Keras is 2.0 or higher.
+
+The program returns helpful error messages if
+the conditions above are not met.abs
+
+Proceed to Lesson 2 when all tests pass.
