ImportError: DLL load failed: The specified module could not be found

While executing tensorflow via Jupyter 
 import tensorflow as tf 

getting following error "ImportError: DLL load failed: The specified module could not be found"

Solution:

Downgraded TensorFlow to 1.10.0 and it worked

# GPU package for CUDA-enabled GPU cards
pip install tensorflow-gpu==1.10.0
# Current release for CPU-only
pip install tensorflow==1.10.0

Also verify if following DLL are present in C:\Windows\System32 folder:

msvcp71.dll, msvcr71.dll, nvcuda.dll

Else download them from the web and,

Save them to your C:\Windows\System32 folder.

Save them to your C:\Windows\SysWOW64 folder as well (if you have a 64-bit operating system)
