Miniconda is an easy to install, minimal python distribution. Users can use miniconda to create virtual python environments to manage python modules. The instructions that follow are for linux.
Installation
Download miniconda
login-1-95 ~ >: wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh --2020-07-29 16:24:59-- https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh Resolving repo.anaconda.com (repo.anaconda.com)... 104.16.131.3, 104.16.130.3, 2606:4700::6810:8203, ...

Run the installation
login-1-96 ~ >: chmod +x Miniconda3-latest-Linux-x86_64.sh login-1-96 ~ >: ./Miniconda3-latest-Linux-x86_64.sh
Accept the license and the default location. After python and some packages are installed you will be prompted to run conda init. Enter 'yes' at the prompt.
When the installation is complete the following appears:
> For changes to take effect, close and re-open your current shell. < If you'd prefer that conda's base environment not be activated on startup, set the auto_activate_base parameter to false: conda config --set auto_activate_base false Thank you for installing Miniconda3!
Since you will likely be maintaining your own virtual environments, it is recommended not to activate the base environment on startup.
login-1-101 ~ >: conda config --set auto_activate_base false
Log off and log in again.
Create and Activate a Conda Virtual Environment
The following example will create a new conda environment based on python 3.7 and install tensorflow in the environment.
login-1-105 ~ >: conda create --name tf python=3.7
Collecting package metadata (current_repodata.json): done
Solving environment: done
## Package Plan ##
environment location: /home/g/guest24/miniconda3/envs/tf
added / updated specs:
- python=3.7
The following packages will be downloaded:
<output snipped>
Proceed ([y]/n)?y
<output snipped>
#
# To activate this environment, use
#
# $ conda activate tf
#
# To deactivate an active environment, use
#
# $ conda deactivate
Activate the new 'tf' environment
login-1-106 ~ >: conda activate tf (tf) login-1-107 ~ >:
Install tensorflow-gpu
(tf) login-1-107 ~ >: conda install -c anaconda tensorflow-gpu

Check to see if tensorflow can be loaded

Simple tensorflow test program to make sure the virtual env can access a gpu. Program is called "tf.gpu.test.py"
import tensorflow as tf
if tf.test.gpu_device_name():
print('Default GPU Device: {}'.format(tf.test.gpu_device_name()))
else:
print("Please install GPU version of TF")
