Unable to install pyAudio package

I am building a speech recognition program but can't install pyAudio.
I have installed Microsoft visual c++ 14.0.0 but still, I am getting another error. I can't understand what is going wrong here please help me out.

These are notes for installation on Microsoft Windows:
pip will fetch and install PyAudio wheels (prepackaged binaries). Currently, there are wheels compatible with the official distributions of Python 2.7, 3.4, 3.5, and 3.6. For those versions, both 32-bit and 64-bit wheels are available.
You are using Python 3.7, which is not compatible with PyAudio. However...
EDIT:
As user #Dalen states, there are prebuilt binaries (.exe files) for pyAudio. I installed from their archive stated in documentation but importing pyAudio had an output:
There are unofficial binaries for Windows on this site: https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyaudio .
Download the proper one and install it.

Download the binary installer for Windows and just install the PyAudio package with no nonsense.
PyAudio is built on top of portaudio library and you require portaudio to be there. The binary installer comes with precompiled version of portaudio as a dynamically linked library and there is no need for hunting and compiling the source.
PyAudio is a great library, enjoy working with it.

pip install pipwin
pipwin install pyaudio
Try these commands in prompt. It does not require any manual downloads or searches etc.
pipwin is a complementary tool for pip on Windows. It is capable of installing unofficial python package binaries for Windows provided by Christoph Gohlke

the key info in the error message is "Cannot open include file: 'portaudio.h': No such file or directory"
so you should google it, and you will find it have an answer in stackoverflow:

the current version PyAudio 0.2.11 is not supported for Python 3.7

Getting error while installing pyaudio in windows 10

I am a beginner in python language. I have written a test function in python for converting speech-to-text :
def getAudioFromMicrophone():
r = sr.Recognizer()
with sr.Microphone() as source:
lets_talk.in_female_voice('I am ready for your next command')
r.pause_threshold=1
r.adjust_for_ambient_noise(source,duration=1)
return r.listen(source)
When I run it, it says :
File "D:/PycharmProjects/python-modules/jarvis/jarvis.py", line 5,
in
import pyaudio ModuleNotFoundError: No module named 'pyaudio'
So, I am trying to install pyaudio in my windows 10 which is again showing an error.

This is a problem with Python 3.7 because there isn't a PyAudio wheel for this version of Python for pip to find. To solve this, download a wheel that fits your computer's specs from here. Now, navigate to the folder the wheel was downloaded to in the command prompt and run: pip install (name of the .whl file here). This should work fine if you are on Windows and using Python 3.7.
I got this information from this post.

Try below commands to install the pyaudio on "Windows 10".
pip install pipwin
pipwin install pyaudio

Follow the steps
Step1. Download the PyAudio-0.2.11-cp310-cp310-win_amd64.whl from this link https://pypi.bartbroe.re/pyaudio
Step2. Use the following comand in cmd pip install (path to the file)/PyAudio-0.2.11-cp310-cp310-win_amd64.whl
Now it will install in my case hope this will help you too.

Almost 100% of the times when I get Visual Studio errors when using pip I fetch the wheel file of the module I wish to install, then use pip on that local file.
https://www.lfd.uci.edu/~gohlke/pythonlibs/#pyopencl
The link I provided will take you to the pyopencl area, this website is a wheel repository for many modules, I used it to install PyCairo as well when it was giving me VS errors. Select the pyopencl module that matches your Python version (For Python 3.7 it will be -cp37-), then select what OpenCL version you wish to use (For CL 2.1 it is +cl21-), then lastly select "amd64" or "win32" if you're on a 64-bit or 32-bit OS. Once you have the file downloaded point pip in the direction of the file, example command: pip install C:\Users\Mihir\Downloads\pyopencl-2018.2.2+cl21-cp37-cp37m-win_amd64.whl that will then install module (Treat a wheel file like a compressed ZIP or TAR). Make sure you have pyopencl prerequisites, which are numpy and cffi (It says Mako too, but I think it works without it).

I faced same problem and i couldn't install pyopencl. I was using python 3.7 in 64 bit windows. So i used pyopencl‑2018.2.5+cl21‑cp37‑cp37m‑win_amd64.whl version. But unfortunately it didn't work.
So i tried with pyopencl‑2018.2.5+cl21‑cp37‑cp37m‑win32.whl version and then it installed successfully.

Put pyopencl-2018.2.2+cl21-cp37-cp37m-win_amd64.whl in System32,
then tap in the power shell
pip install pyopencl-2020.3.1+cl21-cp39-cp39-win_amd64.whl

Could not install pycocotools in windows: fatal error C1083: Cannot open include file: 'io.h': No such file or directory error:

I'm new to machine learning and have started with a windows 8.1 pc having GeForce GTX 540M. I followed this tutorial to get started with the object detection models. I built my own dataset and tried to train it as per the tutorial but with "ssd_mobilenet_v1_coco_2017_11_17" model. But could not perform it successfully as i had troubles with the "train.py" file given in the tutorial.
So I googled and found that we have to use "model_main.py" to train the model. While trying to train using "model_main.py" I got this error:
"ImportModuleError: No module named 'pycocotools' was found"
So I tried to install the cocoapi from this link . I followed the instructions as given, but got stuck with the error shown below, I've tried a lot of solutions but nothing worked. Any help will be much appreciated.

easy fix, use pip install pycocotools-windows

First install Visual C++ 2015 Build Tools from https://go.microsoft.com/fwlink/?LinkId=691126 with default selection.
Then,
pip install git+https://github.com/philferriere/cocoapi.git#egg=pycocotools^&subdirectory=PythonAPI

you can try:
pip install pycocotools-windows
it's worked for me :) on windows station :

I was getting the same error
ValueError: 'pycocotools/_mask.pyx' doesn't match any files
So I cloned https://github.com/waleedka/coco to my local device. Then when I was running make I was getting the above error.
the exact command I was running was--
C:\Users\Admin\Desktop\coco-master>python3 PythonAPI/setup.py build_ext install
I was when I was running above command I got the problem.
Then I found out a solution on the issues page of the same repository. It happens that you have to cd into PythonAPI then run--
python setup.py build_ext --inplace
That solved some problems for me.
Moreover some people were saying they still got problems but when they used python3 instead of python their problem was solved.

Try the following command (it worked for me on Windows 10, Python 3.7.5, and Visual 2017) :
pip3 install "git+https://github.com/philferriere/cocoapi.git#egg=pycocotools&subdirectory=PythonAPI"
(from https://github.com/cocodataset/cocoapi/issues/169#issuecomment-462528628)

If you are getting this ERROR: Command errored out with exit status 1 or 2
Then install this:
pip install git+https://github.com/philferriere/cocoapi.git#egg=pycocotools^subdirectory=PythonAPI

pip install pycocotools-windows
worked for me

Please help me solve these issues, I need it for a project and I really need to get it done. I am on Windows 10 (Intel processors) and Python3.4.

As #SaeX says in this answer, you can find the precompiled
WHL of lxml with the required modules and dependencies here.
For Python 3.4 and win10 your file should be lxml‑4.1.0‑cp34‑cp34m‑win_amd64.whl. Then you can install it by using pip:
pip install lxml‑4.1.0‑cp34‑cp34m‑win_amd64.whl

For python 3.4 or above,
In command Prompt,
type pip3 install lxml in case if you want to download and install from network automatically
otheriwse, download .whl file of lxml from the below
For 32 bit : Download Here
For 64 bit : Download Here
After downloading the wheel file,navigate your command prompt to the location where the .whl file is downloaded and then try
pip3 install "downloaded whl file name"

For windows, you can install lxml by exe file if also failed by whl. You can download it from lxml
Hope this can help you.
