To use the Python SDK elsewhere, you can install from PyPI or a distribution package.
-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.
+As of Arvados 2.2, the Python SDK requires Python 3.6+. The last version to support Python 2.7 is Arvados 2.0.4.
h2. Option 1: Install from a distribution package
Note:
-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:

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@.
If you installed from a distribution package (option 2): the package includes a virtualenv, which means the correct Python environment needs to be loaded before the Arvados SDK can be imported. This can be done by activating the virtualenv first:
<notextile>
-<pre>~$ <code class="userinput">source /usr/share/python2.7/dist/python-arvados-python-client/bin/activate</code>
+<pre>~$ <code class="userinput">source /usr/share/python3/dist/python3-arvados-python-client/bin/activate</code>
(python-arvados-python-client) ~$ <code class="userinput">python</code>

Or alternatively, by using the Python executable from the virtualenv directly:
<notextile>
-<pre>~$ <code class="userinput">/usr/share/python2.7/dist/python-arvados-python-client/bin/python</code>
+<pre>~$ <code class="userinput">/usr/share/python3/dist/python3-arvados-python-client/bin/python</code>
