Verifying that conda is installedTo verify that conda is installed, in your terminal window or an Anaconda Prompt, run:conda --versionConda responds with the version number that you have installed, such as conda 4.10.3.(base) yongqiangyongqiang:~/tensorflow_work/tensorflow$ conda --version conda 4.10.3 (base) yongqiangyongqiang:~/tensorflow_work/tensorflow$2. Determining your conda versionIn addition to theconda --versioncommand explained above, you can determine what conda version is installed by running one of the following commands in your terminal window or an Anaconda Prompt:conda infoORconda -V3. Updating conda to the current versionTo update conda, in your terminal window or an Anaconda Prompt, run:conda update condaConda compares versions and reports what is available to install. It also tells you about other packages that will be automatically updated or changed with the update. If conda reports that a newer version is available, typeyto update:Proceed ([y]/n)? y(base) yongqiangfamu-sys:~$ conda --version conda 4.7.12 (base) yongqiangfamu-sys:~$ (base) yongqiangfamu-sys:~$ conda info active environment : base active env location : /home/yongqiang/miniconda3 shell level : 1 user config file : /home/yongqiang/.condarc populated config files : conda version : 4.7.12 conda-build version : not installed python version : 3.7.4.final.0 virtual packages : __cuda9.1 base environment : /home/yongqiang/miniconda3 (writable) channel URLs : https://repo.anaconda.com/pkgs/main/linux-64 https://repo.anaconda.com/pkgs/main/noarch https://repo.anaconda.com/pkgs/r/linux-64 https://repo.anaconda.com/pkgs/r/noarch package cache : /home/yongqiang/miniconda3/pkgs /home/yongqiang/.conda/pkgs envs directories : /home/yongqiang/miniconda3/envs /home/yongqiang/.conda/envs platform : linux-64 user-agent : conda/4.7.12 requests/2.22.0 CPython/3.7.4 Linux/4.13.0-36-generic ubuntu/16.04.5 glibc/2.23 UID:GID : 1001:1001 netrc file : None offline mode : False (base) yongqiangfamu-sys:~$ (base) yongqiangfamu-sys:~$ conda -V conda 4.7.12 (base) yongqiangfamu-sys:~$ (base) yongqiangfamu-sys:~$ nvcc -V nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2017 NVIDIA Corporation Built on Fri_Sep__1_21:08:03_CDT_2017 Cuda compilation tools, release 9.0, V9.0.176 (base) yongqiangfamu-sys:~$conda update pythonupdates to the most recent in the series, so any Python 2.x would update to the latest 2.x and any Python 3.x to the latest 3.x.4.
