-The Python SDK provides access from Python to the Arvados API and Keep. It also includes a number of command line tools for using and administering Arvados and Keep, and some conveniences for use in Crunch scripts; see "Crunch utility libraries":crunch-utility-libraries.html for details.
+The Python SDK provides access from Python to the Arvados API and Keep, along with a number of command line tools for using and administering Arvados and Keep.
h2. Installation
To use the Python SDK elsewhere, you can install from PyPI or a distribution package.
-{% include 'notebox_begin' %}
-The Python SDK requires Python 2.7.
-{% include 'notebox_end' %}
+As of Arvados 2.1, the Python SDK requires Python 3.5+. The last version to support Python 2.7 is Arvados 2.0.4.
-h3. Option 1: Install with pip
+h2. Option 1: Install from a distribution package
-This installation method is recommended to make the SDK available for use in your own Python programs. It can coexist with the system-wide installation method from a distribution package (option 2, below).
+This installation method is recommended to make the CLI tools available system-wide. It can coexist with the installation method described in option 2, below.
-Run @pip-2.7 install arvados-python-client@ in an appropriate installation environment, such as a virtualenv.
+First, configure the "Arvados package repositories":../../install/packages.html
-If your version of @pip@ is 1.4 or newer, the @pip install@ command might give an error: "Could not find a version that satisfies the requirement arvados-python-client". If this happens, try @pip-2.7 install --pre arvados-python-client@.
+{% assign arvados_component = 'python3-arvados-python-client' %}
-h3. Option 2: Install from a distribution package
+{% include 'install_packages' %}
-This installation method is recommended to make the CLI tools available system-wide. It can coexist with the installation method described in option 1, above.
+h2. Option 2: Install with pip
-First, "add the appropriate package repository for your distribution":{{ site.baseurl }}/install/install-manual-prerequisites.html#repos.
+This installation method is recommended to use the SDK in your own Python programs. If installed into a @virtualenv@, it can coexist with the system-wide installation method from a distribution package.
-On Red Hat-based systems:
+Run @pip install arvados-python-client@ in an appropriate installation environment, such as a @virtualenv@.
-<notextile>
-<pre><code>~$ <span class="userinput">sudo yum install python-arvados-python-client</code>
-</code></pre>
-</notextile>
+Note:
-On Debian-based systems:
+The SDK uses @pycurl@ which depends on the @libcurl@ C library. To build the module you may have to first install additional packages. On Debian 9 this is:
-<notextile>
-<pre><code>~$ <span class="userinput">sudo apt-get install python-arvados-python-client</code>
-</code></pre>
-</notextile>
+<pre>
+$ apt-get install git build-essential python-dev libcurl4-openssl-dev libssl1.0-dev
+</pre>
+
+For Python 3 this is
+
+<pre>
+$ apt-get install git build-essential python3-dev libcurl4-openssl-dev libssl1.0-dev
+</pre>
+
+If your version of @pip@ is 1.4 or newer, the @pip install@ command might give an error: "Could not find a version that satisfies the requirement arvados-python-client". If this happens, try @pip install --pre arvados-python-client@.
-h3. Test installation
+h2. Test installation
If the SDK is installed and your @ARVADOS_API_HOST@ and @ARVADOS_API_TOKEN@ environment variables are set up correctly (see "api-tokens":{{site.baseurl}}/user/reference/api-tokens.html for details), @import arvados@ should produce no errors.
