Cool! Funny that the acceptance rate is so low. That proposal is close to the posterior though. Is Inverse Gamma just that pathological?

Looks like the Travis build failed due to a PEP8 error. In keeping convention with the other example scripts, I also recommend ending decimals with 0s, e.g., 7.0 instead of 7. and removing significant digits, e.g., 0.7 instead of 0.70. As a tip, you can also use tf.zeros(1000) which is slightly cleaner than tf.zeros([1000]).
