Cannot Install CNTK - pip

When I try to install CNTK using pip, it gives me the following error - Could not find a version that satisfies the requirement cntk (from versions: )
No matching distribution found for cntk
I'm using Python 3.7 and windows 10.

cntk currently provides wheels for Python 2.7, 3.5 and 3.6, Linux 64 bit and w64. There is no source code hence there is no way to compile for Python 3.7.
You can try to install from sources or use Python 3.6.

Install TensorFlow 2.2 using Conda on macOS

Just checking if anyone knows whether Anaconda Project has released TensorFlow 2.2 and above for macOS users? From my understanding, this version of TF exists for all platforms except Mac.
Thanks for the help
you have the option to check things like this on the anaconda website. Just go to https://anaconda.org/anaconda/tensorflow and you will see:
linux-64 v2.2.0
win-64 v2.1.0
osx-64 v2.0.0
so the newest version available for macOS from the anaconda channel is (currently) 2.0.0
Alternatively you can also always run
conda search tensorflow
to see which versions are available for your platform
Note
From my understanding, this version of TF exists for all platforms except Mac
From anaconda, yes, but you are definately able to find this version on pypi, i.e. use pip install to install it

Which python can access a pre-compiled version of Quantlib?

I was wondering if anybody knows where such an information is readily available.
Installing an UN-compiled version of QuantLib on Windows is such a hassle that I would rather
modify my python version in order to pip install Quantlib.
Thank You.
You can see the wheels available from PyPI at https://pypi.org/project/QuantLib/#files. Look for the ones with a "win" in their name (e.g., QuantLib-1.16.1-cp37-cp37m-win_amd64.whl, where the cp37 part stands for CPython 3.7 and the amd64 part indicates 64-bit architecture). As of now, there are wheels for 64-bit Python 3.5, 3.6 and 3.7.

Tensorflow import error (Windows10) (python3.5.3) (tensorflow-gpu #243 nightly binary)

Environment:
Windows10
Python 3.5.3 64bit
CUDA Toolkit 8.0
cuDNN v5.1(extracted to Toolkit8.0 files)
Visual Studio Community 2015
Nightly binary#243 Tensorflow GPU version (pip install tensorflow_gpu-1.2.1-cp35-cp35m-win_amd64.whl)
The package has not been installed correctly, and the file _pywrap_tensorflow.pyd is not present in the C:\...\Lib\site-packages\tensorflow\python
After I got nearly the same error as #5949, I tried mrry's tensorflow_self_check.py.
The output is:
ERROR: Failed to import the TensorFlow module.
Python version is 3.5.
TensorFlow is installed at: C:\Python\Python35\lib\site-packages\tensorflow
All required DLLs are present. Please open an issue on the
TensorFlow GitHub page: github.com/tensorflow/tensorflow/issues
However, I can import the tensorflow successfully if I use the below version:
pip install --upgrade https://storage.googleapis.com/tensorflow/windows/gpu/tensorflow_gpu-0.12.0-cp35-cp35m-win_amd64.whl
So, what's wrong the tensorflow_gpu-1.2.1 version?
I really hope someone can help me solve it completely. Thank you!
I would suggest to use Anaconda for the windows, if you want to try tensorflow. The number of issues is very less.
https://www.tensorflow.org/install/install_windows
But if you really want to work without anaconda.
Check your path to Cuda, Cudnn and python.
Ensure that cudnn is v5.1
TensorFlow 1.3 or later requires cuDNN 6.
Installing the Microsoft Visual C++ 2015 Redistributable Update 3 (x64 version) can fix it.
Do let me know about after trying above steps.

Error: GTK library is not installed or installed version is not compatible

I'm trying to install the Intel XDK for Linux under CentOS 7.3 (7.3.1611)
But I'm facing a problem witch I'm not able to solve:
Message:
GTK library is not installed or installed version is not compatible
The GTK library is not installed or installed version of the library is not compatible. The graphical user interface of the product requires gtk version 2.20 or higher. Contact your system administrator to install a compliant version of gtk for the INTEL64 architecture or install the product on a compliant system.
In my OS, I've already gtk+ 2.4 installed, but the installer of Intel XDK can't see the package.
I've these packages installed:
yum install gtk*:
Package gtk2-2.24.28-8.el7.x86_64 already installed and latest version
Package gtk2-devel-2.24.28-8.el7.x86_64 already installed and latest version

Package gtk3-3.14.13-20.el7.x86_64 already installed and latest version
Package gtk3-devel-3.14.13-20.el7.x86_64 already installed and latest version
Is there a way to solve this problem ?
