 # Installing OpenL3
 
 Dependencies
 ------------
-#### Tensorflow
-Because Tensorflow comes in CPU-only and GPU variants, we leave it up to the user to install the version that best fits
-their usecase.
-
-On most platforms, either of the following commands should properly install Tensorflow:
-
-    pip install "tensorflow<1.14" # CPU-only version
-    pip install "tensorflow-gpu<1.14" # GPU version
-
-
-**Please note that Tensorflow 2.x is not yet supported. Ensure that an earlier version of Tensorflow is installed.** If you run into further issues with installation, a known working dependency combination is Tensorflow 1.13, Keras 2.0, and Kapre 0.1.4.

+#### Tensorflow
+Starting with `openl3>=0.4.0`, Openl3 has been upgraded to use Tensorflow 2. Because Tensorflow 2 and higher now includes GPU support, `tensorflow>=2.0.0` is included as a dependency and no longer needs to be installed separately.

 Installing OpenL3
 -----------------
 The simplest way to install OpenL3 is by using ``pip``, which will also install the additional required dependencies
