> Traceback (most recent call last):

TensorFlow fails to load runtime after installation from source

I started compiling TensorFlow from source on Ubuntu Linux 16.06 LTS, running the commands from the TensorFlow Linux compilation instructions.
My CUDA and CuDNN setup works, as the pre-compiled TensorFlow nvidia-docker image works.
After using bazel to build the TensorFlow Python wheel, and then installing the wheel with pip, I get the following error message when trying to import TensorFlow:
>>> import tensorflow
Traceback (most recent call last):
File "/home/james/workspace/tensorflow/tensorflow/python/pywrap_tensorflow.py", line 41, in <module>
from tensorflow.python.pywrap_tensorflow_internal import *
ImportError: No module named 'tensorflow.python.pywrap_tensorflow_internal'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/james/workspace/tensorflow/tensorflow/__init__.py", line 24, in <module>

raise ImportError(msg)

ImportError: No module named 'tensorflow.python.pywrap_tensorflow_internal'
Failed to load the native TensorFlow runtime.
See https://www.tensorflow.org/install/install_sources#common_installation_problems

This error happens when you are running Python from the TensorFlow source directory after having installed the Python wheel.
A similar error happens when you try importing TensorFlow before installing the Python wheel.
The solution to this problem is to change your working directory to something else, while still remaining in the virtualenv that you installed the Python wheel to.

when i type :
from Crypto.Hash import SHA512
everything is working fine and i can calculate the hash
but when i type: from Crypto.PublicKey import RSA,or any Crypto.PublicKey library i am getting errors:

Import issue for cvxopt on Windows

I installed cvxopt verbatim from here. On using it from the python prompt, I see the following issue:
>>> import cvxopt
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build\bdist.win32\egg\cvxopt\__init__.py", line 32, in <module>
File "build\bdist.win32\egg\cvxopt\base.py", line 7, in <module>
File "build\bdist.win32\egg\cvxopt\base.py", line 6, in __bootstrap__
ImportError: DLL load failed: The specified procedure could not be found.
>>>
Any ideas to resolve this?

cvxopt requires Numpy-MKL, you can get the windows binary here.
And install the cvxopt binary from here
