I added more comments to explain why using python 3.5, Tensorflow 1.4.0, and comments and links for Visual Studio 2015.
I erased the docopt installation and the part for the folders:
Had to paste this “lib” folder from C:\Program Files (x86)\Microsoft Visual Studio 14.0\lib
Into C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\PlatformSDK\lib
Because this might have been only a problem for me. Thanks,
[Download](https://www.anaconda.com/download/#windows) and install Anaconda for Windows. By using Anaconda, you can manage separate environments for different distributions of Python. Python 3 is required as we no longer support Python 2. In this guide, we are using Python version 3.6 and Anaconda version 5.1 ([64-bit](https://repo.continuum.io/archive/Anaconda3-5.1.0-Windows-x86_64.exe) or [32-bit](https://repo.continuum.io/archive/Anaconda3-5.1.0-Windows-x86.exe) direct links).

After installation, you must open __Anaconda Navigator__ to finish the setup. From the Windows search bar, type _anaconda navigator_. You can close Anaconda Navigator after it opens.
If environmental variables were not created, in System Variables "Path" add:
If environmental variables were not created, or if you see the error "conda is not recognized as internal or external command", in System Variables "Path" add:
C:\ProgramData\Anaconda3\Scripts
C:\ProgramData\Anaconda3\Scripts
C:\ProgramData\Anaconda3\
C:\ProgramData\Anaconda3
C:\ProgramData\Anaconda3\python.exe
```
## Step 2: Setup and Activate a New Conda Environment
You should see `(ml-agents)` prepended on the last line.
Next, install `tensorflow`. Install this package using `pip` - which is a package management system used to install Python packages. In the same Anaconda Prompt, type in the following command _(make sure you are connected to the internet)_:
Next, install `tensorflow`. Install this package using `pip` - which is a package management system used to install Python packages. Latest versions of Tensorflow won't work, so you will need to make sure that you install version 1.4.0. In the same Anaconda Prompt, type in the following command _(make sure you are connected to the internet)_:
```
pip install tensorflow==1.4.0
```
pip install .
pip install docopt
```
This will complete the installation of all the required Python packages to run ML-Agents.
### Install Nvidia CUDA toolkit
[Download](https://developer.nvidia.com/cuda-toolkit-archive) and install the CUDA toolkit from Nvidia's archive. The toolkit includes GPU-accelerated libraries, debugging and optimization tools, a C/C++ (Step: Visual Studio 2015) compiler and a runtime library and is needed to run ML-Agents. In this guide, we are using version 8.0.61 ([direct link](https://developer.nvidia.com/compute/cuda/8.0/Prod2/network_installers/cuda_8.0.61_win10_network-exe)).

Before installing, please make sure you __close any running instances of Unity or Visual Studio__.

Step Visual Studio 2015: unistall Visual Studio 2017 that comes with the Unity installation, download Visual Studio Enterprise 2015 and install the SDK when installing. If you don't want to install Visual Studio Enterprise 2015, at least install Visual C++ Redistributable for Visual Studio 2015 and Visual Studio 2015 Windows SDK.
Had to paste this “lib” folder from C:\Program Files (x86)\Microsoft Visual Studio 14.0\lib
Into C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\PlatformSDK\lib
Step Visual Studio 2015: CUDA 8.0 is not compatible with Visual Studio 2017, so you will need an older version. Uninstall Visual Studio 2017 that comes with Unity, download Visual Studio Enterprise 2015 and install it with the Windows SDK. If you don't want/ can't install Visual Studio Enterprise 2015, you will need Visual C++ Redistributable for Visual Studio 2015 ([direct link](https://www.microsoft.com/en-us/download/details.aspx?id=48145)) and Visual Studio Community 2015 ([direct link](https://www.visualstudio.com/vs/older-downloads/)) with Windows SDK ([direct link]( https://msdn.microsoft.com/en-us/library/mt683786.aspx)).
