I'm trying to do the follow code with OpenAI:
import gym
env = gym.make('CarRacing-v0')
env.reset()
for _ in range(1000):
env.render()
env.step(env.action_space.sample())
but it throws the error:
fn = getattr(mod, attr_name)
AttributeError: module 'gym.envs.box2d' has no attribute 'CarRacing'
And then I try to install box2d by pip install box2d-py throwing this error:

what I have to do to install it successfully?
Windows support is at present moment experimental (source). That being said, on most of the occasions you will get it to work, but some of the functionality could be broken. Proceed with caution.
Here's what could work:
Install Anaconda.
Start Anaconda command line (it adds conda to the PATH).
conda create -c conda-forge -n gymenv swig pip - create base environment.
conda activate gymenv - activate it.
pip install Box2D gym - install base gym with Box2D.
(Optional) pip install gym[all] - install all components of Gym. You might run into errors.
If you get build errors on missing compilers, install Visual Studio Built Tools.
Depending on the component you're using, you might need e.g. pystan. Activate then the conda environment and install it, i.e. conda install pystan.
An alternative could be to try to install Gym directly through conda:
conda create -c conda-forge -c powerai -n gymenv gym swig pip pystan
This will install gym from powerai channel. Might work, but mind that it's not the latest nor seems to be supported by devs.
I got it sorted with just installing swig before gym[box2d] no anaconda needed
pip3 install swig
In my case, I used the conda to install Gym's Box2D:
conda install swig
conda install -c conda-forge gym-box2d
and got rid of this error.
(As a windows user) For me, the solution was to download and install the latest stable version of Build Tools pour Visual Studio (2022 currently). Then the pip install gym[box2d] worked.

I'm using pip 20.2.3 on Linux to install additional packages (extras_require['test']) into a project that was first built using python setup.py build -b _build. In the project's directory, there's also a custom script called build (whose name I shouldn't change). When I run pip install .[test] it complains that build already exists and fails:

I've tried passing --build to pip but the option is marked as deprecated in man page and is obviously ignored.
Is there any other way I can make pip use another name for its build directory (e.g. _build), or is there a way to use python setup.py build -b _build to install only the extras_require['test'] packages?
I installed pcketsphinx on Anaconda using conda-forge in this way.
conda install -c conda-forge pocketsphinx
And then I got the following message

I'm using Anaconda3 and Python 3.7.4 and Windows 10 64bit.
I came across what looks like the same problem and was able to solve it with the following steps. Hopefully this will help you and others, at least to get started. Consider the following general points:
Anaconda/Miniconda had a version of gcc that was picked up as the default compiler and, it seems, was interfering. Make sure gcc is picking up the desired compiler. To see what compilers you have, start up a terminal window, type gcc+TAB (gcc followed by a tab). This should show all the versions you have on your system. Type gcc --version to see which version is the default. And which gcc to find out where it is located, e.g. /Users/PatrickT/miniconda/bin/gcc
You want to ensure that your system's PATH can find your compiler. This may be done by adding an export command to your bash profile. On Catalina, apparently, the bash profile information would be placed in .zshrc. To find this file, type COMMAND+SHIFT+E to make invisible files visible and look in your home directory (/Users/PatrickT in my case). For instance, add a line like export PATH="/usr/local/gcc-10/bin:$PATH". The path is of course dependent on your system.
To make sure miniconda was not interfering, I took it off the PATH altogether. I also installed the latest version of xcode from the apple binaries. Once I had an updated version of the gcc compiler found by my system, I was able to install pocketsphinx as well as other programs that I was having problems with, like kaldi or zlib.
Getting miniconda to work again without interfering with gcc is a problem I haven't solved. As soon as I put miniconda back on the PATH, the default gcc reverted to the miniconda version. To be continued...
You can:
pip install pipwin
and
pipwin install pocketsphinx

I'm installing from a folder that contains the needed packages downloaded using the command pip download , then installing them offline using pip install -r requirements.txt --no--index --find-links=pkgs
The link below, the person suggests using
easy_install when installing python packages in a virtual environment
example
Using this command helped path/to/python/python3.6 -m pip install -r requirements.txt --no-index --find-links=path/to/pkgs
EDIT: Looks like I have to install Visual Studio 2015...Can I install dlib without VS 2015? I already have older versions pre-installed with Windows.
I am using Python 3.5, trying to install dlib on PyCharm in the terminal and this is what I am getting, and every search on these errors I do... I find stuff on Visual Studio which I don't have the GUI + I don't have vcvarsall.bat in the VC folder of any of the Visual Studio versions (8, 11, 12, 14). I have searched a good amount before posting this question on the Web.
Do I need to download Visual Studio latest version to get vcvarsall.bat ?
