No couchbase.subdocument module after upgrade to couchbase 4.5

Hi, I upgraded the couchbase to 4.5. I assume it will update the python modules inlcluding subdocument.
However it seems the couchbase server is upgraded successfully, but no subdocument module is found.

May I ask where to find these newly added modules and where to get the packages to install these modules.

best,

I think I got a solution which is to upgrade through pip. It can upgrade to the latest 2.1.2.
However, it complains about the following:

building ‘couchbase._libcouchbase’ extension

compilation terminated.

After upgrading the libcouchbase-dev to the latest version, I am able to install couchbase python client library.

Though it says the installation is successful, there are still some Errors, for example:
File “/usr/local/lib/python2.7/dist-packages/acouchbase/iterator.py”, line 17
yield from self._future
^
SyntaxError: invalid syntax

Is it normal? Do I need to worry about it when I use the library in production?

No, this is not something you need to worry about. This is because it’s trying to byte-compile a Python3-only module, hence the error. This is perfectly normal.
