How to install gi module for anaconda python3?
If you're using conda virtualenv for python-3, you can use
$ conda install -c conda-forge pygobject
in your virtualenv
You can read more about this on: https://anaconda.org/conda-forge/pygobject
This is how you do it: (example for Linux Mint and python3)
First install gi
module using your distro package manager. For Linux Mint it would be:
sudo apt-get install python3-gi
Then run your distro python to check where the module is located:
$ /usr/bin/python3
Python 3.5.2 (default, Sep 10 2016, 08:21:44)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>> print(gi)
<module 'gi' from '/usr/lib/python3/dist-packages/gi/__init__.py'>
So in my case the module gi
was installed to /usr/lib/python3/dist-packages/gi
. Assuming you have your anaconda installed in /home/kossak/anaconda3
, create a link to gi module in the proper folder:
ln -s /usr/lib/python3/dist-packages/gi /home/kossak/anaconda3/lib/python3.5/site-packages/
If you have conda virtual environment and want gi
module to be available there, the path should be a bit different. Assuming the virtual env is called TEST:
ln -s /usr/lib/python3/dist-packages/gi /home/kossak/anaconda3/envs/TEST/lib/python3.5/site-packages/
and it works:
$ python3
Python 3.5.2 |Anaconda custom (64-bit)| (default, Jul 2 2016, 17:53:06)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-1)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import gi
>>>
for me
conda install -c pkgw/label/superseded gtk3
worked
If you want to perform a proper install (without soft linking) inside a Linux anaconda environment. Keep in mind that the errors may vary if you have not installed gcc previously (I assumed it was installed by default when I posted, however not everyone does so). Install it if you don't know very well what you're doing to avoid missunderstandings
Create or open your conda environment.
Attemp to install pygobject (don't worry, it will most likely throw an error):
pip install pygobject
In linux, it will promp the usual installation progress followed by an error:
(...) Please, try executing the following in your system: sudo apt install libgirepository1.0-dev
Depending on your operation sistem or installed dependencies, the command name or package name may vary. Just follow the instructions and allow the system to install your packets. This step doesn't change anything, is just to give you the precise info of the package you need on your system. If you run this on Windows, it will ask you to install a specific version of Visual Studio. If you are in Windows, download the required Visual Studio from MS website, install it, reboot your computer and go to step 5 (in my case I never needed step 4 in windows, however, I'm not a MS expert.
Close your conda environment
conda deactivate
Next you need to install pygobject from conda-forge repository in your conda environment. You can add the repo to your favourite conda package manager or simply run the following command as root (it is important to be root). I did it outside the project, but you may do it inside:
conda install -c conda-forge pygobject
In my case conda was not in the path. I had is installed in:
/opt/anaconda3/bin/
You can run the following command from your normal user to find out where conda is:
which conda
Open the conda environment
source activate <your env name>
or the corresponding anaconda activate syntax (I never use it so I cant remember precisely)
Repeat the first step and now the installation wont fail:
pip install pygobject
OR if you specifically want to install gi you can run:
pip install pgi
the correct package is "pgi" NOT "gi"
As gi is a dependency of pygobject, everything will get properly installed. You can check it by running
python
>>> import gi
You may find the following usefull for Windows, although you may need to work it out a bit: GStreammer python bindings on Windows
