Perhaps confusingly, the python-louvain
package does not have much to do with this louvain-igraph
package. You should be able to install louvain-igraph
in a conda environment simply using
conda install -c vtraag louvain
I'm not sure if that is the path you followed to install the package? The error you get using Anaconda is actually an error from matplotlib
, not from louvain-igraph
.
On another note, the louvain-igraph
package has become deprecated, in favour of the new leidenalg
package. From scverse/scanpy#350, it seems that the new leidenalg
package will be supported in scanpy
shortly.
from louvain-igraph.
I found in the third one I still could not install louvain in my ordinary venv virtual environment through "conda install -c vtraag louvain" and it says Solving environment: failed
Traceback (most recent call last):
..
File "../python-anaconda3/created-20170712/lib/python3.6/site-packages/conda/history.py", line 158, in _parse_old_format_specs_string

IndexError: list index out of range
I am guessing this is because I am using a read-only conda environment. I will try the other two methods which I could install louvain but got some error about matplotlib.
Thanks
from louvain-igraph.
OK, let me know if you resolved the issue, then I will close the issue.
from louvain-igraph.
I found actually in my first use of louvain with python 3.5.2, I actually also encountered the same issue with louvain as the second one with matplotlib:

I this this libstdc++ issue is also with louvain. Do you have any idea about this?
from louvain-igraph.
See this issue for a potential solution: vtraag/leidenalg#2. Does this solve your problem?
from louvain-igraph.
I still got the error messages for my anaconda virtual environment if I degrade my libgcc to 5.2.0 from 7.2.0. This error is with matplotlib:
File "../.conda/envs/wgan_env/lib/python3.6/site-packages/matplotlib/path.py", line 17, in <module>
from . import _path, rcParams
ImportError: /lib64/libstdc++.so.6: version `CXXABI_1.3.9' not found (required by ../.conda/envs/wgan_env/lib/python3.6/site-packages/matplotlib/_path.cpython-36m-x86_64-linux-gnu.so)
Previously I used normal environment, the similar error is with louvain:
File "../.local/lib/python3.5/site-packages/louvain/functions.py", line 3, in <module>
from . import _c_louvain
ImportError: /lib64/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by /home/hengshi/.local/lib/python3.5/site-packages/louvain/_c_louvain.cpython-35m-x8$
I feel this is complicated and do not know how to solve it
from louvain-igraph.
It is a bit difficult to see what the problem is.
Could you perhaps do the following?
Create a new clean conda environment (named "test", assuming you don't already have such an environment)
conda create --name test
and then after activating the new environment using
conda activate test
could you install the packages as follows
conda install -c conda-forge igraph python-igraph
conda install -c vtraag louvain-igraph
Does the louvain-igraph
package work correctly after this? In other words, if you run python
and do import louvain
, what error (if any) do you get?
from louvain-igraph.
I could run those lines and install louvain seeming. But I could not import louvain and could not find louvain in my conda list.
(test) [XX]$ conda install -c conda-forge igraph python-igraph

Hi, I installed louvain and solved the issue. I found that it should be:
conda install -c vtraag louvain
rather than installing louvain-igraph
from louvain-igraph.
Yes, quite right, sorry about that 👍
from louvain-igraph.
Thanks!

What are the differences between python-louvain and louvain-igraph?
I already made a community detection with louvain on networkX, but now I must implement it in python-igraph
from louvain-igraph.
python-louvain
works with networkx
, while louvain-igraph
works with python-igraph
. This package also implements a variety of other methods, such as CPM, Surprise and Significance. It can also work with multiplex networks. However, note that this package has been superseded by the leidenalg
package. You are strongly recommended to use that package instead of louvain-igraph
package.
