Tensorboard projector will compute PCA endlessly

Question

I have just over 100k word embeddings which I created using gensim, originally each containing 200 dimensions. I've been trying to visualize them within tensorboard's projector but I have only failed so far. My problem is that tensorboard seems to freeze while computing PCA. At first, I left the page open for 16 hours, imagining that it was just too much to be calculated, but nothing happened. At this point, I started to try and test different scenarios just in case all I needed was more time and I was trying to rush things. The following is a list of my testing so far, all of which failed at the same spot, computing PCA:

• I plotted only 10 points of 200 dimensions;
• I retrained my gensim model so that I could reduce its dimensionality to 100;
• Then I reduced it to 10;
• Then to 2;
• Then I tried plotting only 2 points, i.e. 2 two dimensional points;

I am using Tensorflow 1.11; You can find my last saved tensor flow session here, would you mind trying it out?

I am still a beginner, therefore I used a couple tutorial to get me started; I used Sud Harsan work so far.

Any help is much appreciated. Thanks.

Updates:

A) I've found someone else dealing with the same problem; I tried the solution provided, but it didn't change anything.

B) I thought it could have something to do with my installation, therefore I tried uninstalling tensorflow and installing it back; no luck. I then proceeded to create a new environment dedicated to tensorflow and that also didn't work.

C) Assuming there was something wrong with my code, I ran tensorflow's basic embedding tutorial to check if I could open its projector's results. And guess what?! I still can't go past "Calculating PCA"

Now, I did visit the online projector example and that loads perfectly.

Again, Any help would be more than appreciated. Thanks!

Answer 1

I have the same problem with word2vec_basic.py

My environment: win10, conda, python 3.6.7, tensorflow 1.11, tensorboard 1.11

That may not your fault because I roll back tensorflow & tensorboard from 1.11 to 1.7

And guess what?! The projector appears just a few seconds!

Update 10/11

tensorboard & tensorflow 1.12 are available in conda today, I take a try and this problem seems to be fixed.
