Python and Virtualenv: In this approach, you install TensorFlow and all of the packages required to use TensorFlow in a Python virtual environment. This isolates your TensorFlow environment from other Python programs on the same machine. Native pip: In this method, you install TensorFlow on your ...
The CUDA "runtime" is part of the NVIDIA driver.The CUDA runtime version has to support the version of CUDA you are using for any special software like TensorFlow that will be linking to other CUDA libraries (DLL's). As of this writing TensorFlow (v1.13) is linkin...
Learn how to install TensorFlow and start building machine learning models. This guide covers installation steps for various processors.
TensorFlow has a built-in functionget_shape()that returns the tensor shape on which it is called. In simpler words, if you have created a tensor containing values and want to know its dimension or size, call the TensorFlowget_shapefunction on that created tensor. The syntax for using Tensor...
the tensorflow with pip, we can see a warning message:"The TensorFlow library wasn't compiled to use SSE4.2 instructions, but these are available on your machine and could speed up CPU computations." when import tensorflow. so, we need to compile the tensorflow library to speed up ...

First, import TensorFlow. import tensorflow as tf Use thetf.constant()function of TensorFlow to create a tensor object, as shown below. tensor_data = tf.constant([[5, 8], [1, 4]]) # tensor data or object Now check the type oftensor_datausing thetype()function of Python. ...
