• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): MacOS
• TensorFlow installed from (source or binary): binary
• TensorFlow version (use command below): 1.8
• Python version: 3.6
• Bazel version (if compiling from source): N/A
• GCC/Compiler version (if compiling from source): N/A

If you print a tensor of shape [n, 4] with tf.Print, by default (summarize=3 is the default value), you get:

[[9 21 55]...]

which wrongly looks like your tensor is of shape [n, 3].

The correct output should be:

[[9 21 55...]...]

Here is what you get with tf.Print(summarize=10):

[[9 21 55 30][190 -42 236 4][89 -5]...]

Now the vectors of size 4 are visible although the last one is still wrong (looks like a vector of size 2
)

Added a PR #20768 for the fix.
