Question: I have conda 4.8.3 and Python 3.7.4 on Windows 8.1. I have tf 2.0.0 installed in a conda environment. How do I upgrade to 2.2.x? Or, how do I just install 2.2.x in a conda environment? Edit 1: pip install --upgrade tensorflow says: Requirement already up-to-date: tensorflow in d:\anaconda3\envs\tf2\lib\site-packages (2.1.0) but tf version is still 2.0. Edit 2: conda install tensorflow==2.2.0 says: PackagesNotFoundError: The following packages are not available from current channels:   tensorflow==2.2.0  I did have some luck here. Edit 3: (tf2) D:\ray\dev\covid-19>conda list -n tf2 # packages in environment at D:\Anaconda3\envs\tf2: # # Name Version Build Channel _anaconda_depends 2019.03 py37_0 _ipyw_jlab_nb_ext_conf 0.1.0

Answer: There are two methods 1. Install into virtual environment with pip TensorFlow virtualenv --system-site-packages -p python3 ./venv  then you need to activate your new environment pip install --upgrade pip pip list # show packages installed within the virtual environment this command for quit deactivate # don't exit until you're done using TensorFlow we finish by installing tensor pip install --upgrade tensorflow  2. Install in your system python3 --version pip3 --version virtualenv --version  Ubuntu sudo apt update sudo apt install python3-dev python3-pip sudo pip3 install -U virtualenv # system-wide install  then pip3 install --user --upgrade tensorflow # install in $HOME
