I'm having trouble importing the nlopt library in Python 3.7.4.
I'm using anaconda, but as nlopt isn't available through conda install, I've installed nlopt with pip.
Here is the error message:
>>> import nlopt

conda install -c conda-forge nlopt

I installed the quickfix 1.15.1 by pip install quickfix-1.15.1-cp36-cp36m-win_amd64.whl downloaded from web.
When I try like:
import quickfix
errors:

If you are sure that quickfix is correctly installed in your environment and the PYTHONPATH has access to this environment, then you can try to check the option 'Load conda env vars before run?' on Window -> Preferences -> PyDev -> Interpreters -> Python Interpreter.
It's possible that the import is failing because that package is using an environment variable to load the modules, and PyDev by default is not loading this variable before running the script.

I've installed CPU version of Tensorflow on the Anaconda3-5.2.0-Windows-x64 on the Windows 10 with the following sequence of commands:
conda create -n tensorflow pip python=3.6
activate tensorflow
pip install --ignore-installed --upgrade tensorflow
and no errors occured. But then I've tried to import Tensorflow and the following text appeared

I've checked out some similar questions here and I have installed Microsoft Visual C++ 2015 Redistributable.
Use conda install tensorflow instead of pip
For installations within anaconda virtual environments its preferable to use conda install package_name
or switch back to version <1.6 i.e pip install tensorflow==1.5
Solution reference : GitHub-TensorFlow
When I use the command import tensorflow as tf I get the following error:

I'm using tensorflow gpu 1.1.0 on python 3.5. The code I'm trying to compile is here: https://github.com/aspuru-guzik-group/chemical_vae
Seems like you have no installed MSVCP140.DLL in your system. You can try installing Visual C++ Redistributable, uninstall then install TF again.
If it doesn't work, try to download and import this dll directly as it explained here.
I am trying to install tensorflow-gpu version on my windows 10. I have installed CUDA v8 and cuDNN 6. Following this I tried to install tensorflow-gpu with the help of pip installer. But when I try to import tensoflow, I get the following stacktrace error on my console

Moving my comment to an answer:
From the documentation see this question:
