Cannot Import numpy.core.multiarray about serving HOT 10 CLOSED

I figured it out, I was using anaconda distro..
NumPy dependency was not a problem as TF was built from source and was running fine.
$ conda update numpy seemed to work.. not sure why.. but I hope it helps.

@Irtza Thanks! and sorry for the delay in getting back to you!
We haven't done that much testing on the GPU build in the open source release, and I wasn't sure what would make this problem GPU specific and didn't have time yet to try and reproduce the failure. Glad it worked out for you and thanks for posting the followup fix!

@kirilg not a GPU specific problem I think, I think it was just conda's view of numpy package not consistent with TensorFlow's.. updating numpy through conda, fixed that.

I have the same problem. I am using Ubuntu 15.10 with NumPy 1.11 and has no iead why TensorFlow cannot find my numpy.

@vodp do you have an anaconda distro of python ? if yes, update conda . and then update numpy through anacoda. $conda update numpy

from serving.

No I am not using Anaconda. In Ubuntu I just built numpy from source.

After removing the numpy compiled from source with linkage customization to openblas, re-install numpy from Ubuntu distro sudo apt-get install python-numpy and rebuild with bazel, the error above disappeared but I get a new mystical error

ERROR: /amy/serving/tensorflow_serving/session_bundle/example/BUILD:34:1: Executing genrule //tensorflow_serving/session_bundle/example:half_plus_two failed: bash failed: error executing command /bin/bash -c ...

I'm guessing the error message will include something about not finding the generated output in .runfiles/tf_serving/tensorflow_serving/... in which case the problem could be fixed in one of two ways:

1. Upgrade Bazel to version 0.2.2+
2. For older versions of Bazel, simply run bazel clean once and recompile with bazel build ... as usual. The problem is that older versions of Bazel don't automatically regenerate runfiles in the newly introduced workspace name and still use the old path. Cleaning (only once the first time) and recompiling should fix the problem.

Actually I just install the latest Bazel

bazel clean and rebuild do not help. The error message is very short so that I could not spot where the problem come from

I had a similar problem in ubuntu.
I had updated numpy using: pip install --upgrade numpy but I still had the same problem when import tensorflow:
ImportError: numpy.core.multiarray failed to import

The reason was that I had two different numpy installations (one using apt-get and one using pip). For any strange reason tensorflow was using the installation that was installled using apt-get instead of the one using pip (by default when I do import numpy, python uses the one installed with pip).

I solved it unistalling the apt-get version: apt-get remove python-numpy
