TypeError while importing Magpie.

[Arvind Soma]

When i import magpie, I'm getting the following error:

`from magpie import Magpie

Using TensorFlow backend.

The value you are passing is null (None in Python). Just convert it to string (even an empty string will do)

[Arvind Soma]

Thanks for the reply! I'm getting this error while importing the library, without passing any variables. I set up all the libraries on the server(with Tensorflow=1.8) and I'm getting this error, while it's working on my personal system(TF=1.4). I'm not sure if i should edit the existing library files that are working well with my other projects.

[David Niki]

It seems the problem is in os.path.join() - maybe there is something with your server's directory structure? (especially since you mention this is only happening on your server)

[Arvind Soma]

Well, I tried two things. First I assumed that its a problem with the libraries, so I made a requirements.txt file from my local env(Python 3.5) and then installed it on the server. This didn't work out!

Second, I tried creating a virtual environment using Python 2.7 and its running now. It seems that this problem is with Python 3.5+ and gensim word2vec or smart_open.

[Jan Stypka]

yeah, it seems like a gensim issue. You can also look at their forum for answers, but usually creating a local virtualenv is the best solution. It should work both for Python 2 and 3.

[Arvind Soma]

Thanks for your reply! Yes it seems more likely to be a gensim issue now. I used Python3.5 env on the server with virtualenv from the begining.
Now I had to port my project to Python 2.7 virtualenv on the server and its working well now.
