how to convert/port gensim word2vec to tensorflow projector board.

gensim2projector_tf.py

# required tensorflow 0.12
# required gensim 0.13.3+ for new api model.wv.index2word or just use model.index2word

from gensim.models import Word2Vec
import tensorflow as tf
from tensorflow.contrib.tensorboard.plugins import projector

# loading your gensim
model = Word2Vec.load("YOUR-MODEL")

# project part of vocab, 10K of 300 dimension
w2v_10K = np.zeros((10000,300))
with open("./projector/prefix_metadata.tsv", 'w+') as file_metadata:
    for i,word in enumerate(model.wv.index2word[:10000]):
        w2v_10K[i] = model[word]
        file_metadata.write(word.encode('utf-8') + '\n')
        

# define the model without training
sess = tf.InteractiveSession()

with tf.device("/cpu:0"):
    embedding = tf.Variable(w2v_10K, trainable=False, name='prefix_embedding')

tf.global_variables_initializer().run()

saver = tf.train.Saver()
writer = tf.summary.FileWriter('./projector', sess.graph)

# adding into projector
config = projector.ProjectorConfig()
embed= config.embeddings.add()
embed.tensor_name = 'fs_embedding:0'
embed.metadata_path = './projector/prefix_metadata.tsv'

# Specify the width and height of a single thumbnail.
projector.visualize_embeddings(writer, config)

saver.save(sess, './projector/prefix_model.ckpt', global_step=10000)

# open tensorboard with logdir, check localhost:6006 for viewing your embedding.
# tensorboard --logdir="./projector/"

Hey @rodrigoccurvo , thanks so much for the fix, that did it. However I can only see the indices instead of the actual words, did you run into a similar issue by any chance?

Hi @rodrigoccurvo, thank you for sharing the fix. Great embedding visualization!

Hi @lampts can you please add the dependency of numpy in code.
Thanks

@rodrigoccurvo Hey, can you tell me what other changes you needed to input? I still am stuck at loading...

Here are several small errors such as metadata file path, I have fixed at here https://gist.github.com/BrikerMan/7bd4e4bd0a00ac9076986148afc06507#file-w2v_visualizer-py. Thanks a lot~
@Adamage fixed the loading problem.

@BrikerMan I get the error "w2x_metadata.tsv is not a file" with your fixes. Couldn't figure out what could be the cause; any ideas?

EDIT: modifying the original as commented above worked in the end. Cheers.

The cause of my "Point: Loading... | Dimensions: Loading..." error was related to the fact that my laptop doesn't support WebGl...Dunno if it can be someone else's reason of failure though.
Also be aware that if you're running tensorboard in the Virtualbox lots of functionalities will not work.
