I am trying to install PocketSphinx in Python. I am trying to follow the Uberi speech recognition README, which asks the following:
PyAudio wheel packages for
common 64-bit Python versions on Windows and Linux are included for
convenience, under the third-party/
directory
in the repository root. To install, simply run pip install wheel
followed by pip install ./third-party/WHEEL_FILENAME (replace pip
with pip3 if using Python 3) in the repository root
directory.
I do not understand the instruction here. What FILE_NAME is this referring to? What is this wheel and how does it relate to PocketSphinx?
When you downloaded the PocketSphinx package manually, it must have created a wheel file (the file which does the real job) with a .whl extension in the said directory.
Now, you need to open a terminal in the directory where the .whl extension file is stored, which in this case is third-party.
Once you make sure that the terminal shows the current directory as third-party, go ahead and do a pip install of the wheel file.
Assuming the name of the wheel file to be PocketSphinx.whl,
You'd write:
pip install PocketSphinx.whl
This will do your job if all requirements are met.
And I have a feeling that the name of the wheel file wouldn't be simply PocketSphinx.whl, it'll be long and informative, nonetheless it will always have the extension .whl, by which you shall identify it.
Edit:
I went to the link you provided, and this is the wheel file you need:
pocketsphinx-0.1.3-cp35-cp35m-win_amd64.whl for python 3.5
Or
pocketsphinx-0.1.3-cp27-cp27m-win_amd64.whl for python 2.7
So your command becomes
pip install pocketsphinx-0.1.3-cp35-cp35m-win_amd64.whl
Or
pip install pocketsphinx-0.1.3-cp27-cp27m-win_amd64.whl
As per your python version.
What FILE_NAME is this referring to?
Filename of the binary package file in third-party folder of the repository. For example pocketsphinx-0.0.9-cp27-none-win_amd64.whl. You are supposed to checkout repository first.
What is this 'wheel' and how does it relate to pocketsphix?
wheel is a python package manager to install binary packages. It is used to install python binary package. You can read more here: https://pypi.python.org/pypi/wheel

I am trying to install scipy package for python 2.7 in windows,
The process i followed is as follows:
downloaded a whl file scipy-0.17.1-cp27-cp27m-win32.whl from
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
tried to install by
pip install scipy-0.17.1-cp27-cp27m-win32.whl
error : Requirement 'scipy-0.15.1-cp27-none-win32.whl' looks like
a filename but the file does not exist
scipy-0.15.1-cp27-none-win32.whl is not a supported wheelon this platform.
then tried to install by
pip install file_location\scipy-0.17.1-cp27-cp27m-win32.whl.
error displayed :scipy-0.15.1-cp27-none-win32.whl is not a supported wheel on this platform.
Also i have already upgraded my pip command.
Can anyone suggest me out some valid solutions?
I Think the issue in Python interpreter variant 32 or 64.. if your python is 32-bit then use scipy-0.17.1-cp27-cp27m-win32.whl otherwise if your python is 64Bit then try scipy-0.17.1-cp27-cp27m-win_amd64.whl
I've been trying to install Python's matplotlib library for use with PyPlot, for use with Julia. I managed to get everything in place except for this one final library, and I feel as though I've hit a deadend trying to get it working.
When trying to install matplotlib (I've attempted using pip, regular python install, and easy_install), I get the following message at the very end of the install output, after which it is NOT installed:
* The following required packages can not be built:
* freetype, png
Confused about this, I looked around online and installed both of these (at least, what I think these were). One was the freetype project, and the other was LibPng, which was the closest thing I could find to a "png package" for windows or python in general.
This didn't initially work (for either of them), and I read somewhere that I needed a freetype.dll in my system32 folder. It was a long shot, but I went to where I installed freetype and pulled out the dll and renamed it, placing it in system32. This of course did not work (again, long shot).
Anyway, that's where I'm at. No idea where to go from here, and I'm unsure if I even grabbed the correct "packages" I should be using. Thoughts?
Use a more powerful installer
I would recommend to use Anaconda or Miniconda. In my experience with many Windows users, this is the simplest way to install packages such as matplotlib.
Anaconda
Anaconda comes with many packages for scientists. Matplotlib works out of the box. Just install as user not root.
Minoconda
If you don't want all packages of Ananconda use Miniconda
Conda
Both ways of installation (Anaconda or Miniconda) provide conda. It is an improved pip/virtualenv.
You can install matplotilb with this command:
conda install matplotlib
Enviroments:
You can create a new environment and install the packages you like:
conda create -n my_project35 python=3.5
activate my_project35
conda install matplotlib
or
conda create -n my_project27 python=2.7
activate my_project27
conda install matplotlib
Combine with pip
You can still use pip. conda "understands" what it is doing.
One snake is enough!
[This is for folks using the Linux Bash Shell on Windows 10.]
If you don't want to go the Anaconda route, you can install freetype (and png) by executing the following in the Windows 10 Bash shell:
sudo apt-get install freetype6-dev
The above command will also automatically install libpng. However, due to an error, the system will not 'realize' it has installed freetype, so you'll need to manually install pkg-config:
sudo apt-get install pkg-config
Thereafter you should be able to install matplotlib via pip without further incident.
sudo pip install matplotlib
I tired downloading matplotlib 2.2.2 with python 3.9.5, getting freetype & png errors for hours.
After downloading python 3.7.9 and removing python 3.9.5 from environment variables, installing matplotlib 2.2.2 worked with no problems!
Change your Python Version
Go to https://www.python.org/downloads/windows/, control-f search 3.7.9 and use the webinstaller. Follow all the recommended instructions
In pyvenv.cfg in your project directory switch version number to 3.7.9 and home to C:.....\Python37.
pip3 install alpaca-backtrader-api
I've been at this for nearly 2 hours and I just can't seem to get my head around it. I am a novice Pythoner, it would appear. I am trying to intsall lxml, (needed to install scrapy). I have tried multiple methods (see my other current quesitons).
Currently I am trying the following.
I downloaded the lxml win 32 file for python 2.7 from this website:
https://pypi.python.org/pypi/lxml/3.4.4#downloads
The LXML Binaries are also available here: "http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml"
I download the .whl file.
I then open up CMD, and CD to my download folder. Once in that folder I run the following command (as per the answer to this question here: How do I install a Python package with a .whl file?)
pip install lxml-3.4.4-cp27-none-win32.whl
This is the output:
C:\Users\Charles\Downloads\python>pip install lxml-3.4.4-cp27-none-win32.whl
Downloading/unpacking lxml-3.4.4-cp27-none-win32.whl
Could not find any downloads that satisfy the requirement lxml-3.4.4-cp27- none
-win32.whl
No distributions at all found for lxml-3.4.4-cp27-none-win32.whl
Storing complete log in C:\Users\Charles\AppData\Roaming\pip\pip.log
Can anyone help me figure out what this means/what is going on? How can I execute this file to install the lxml as needed?
Many thanks!!
Edit: I am using Windows 64 bit, but from this question here: "easy_install lxml on Python 2.7 on Windows" the file I have selected appears to be the correct one.
I am using Windows 64 bit and use Scrapy. It took a while for me to figure out the best way to set up my virtualenv because lxml would not simply pip install.
So I did somethine very similar to what you did but it looks at first glance we may just be using different sites. So try downloading this .whl from HERE. Specifically, for your specifications I believe, grab the one that reads
lxml-3.4.4-cp27-none-win_amd64.whl
and then just cd to the downloads folder and pip install lxml-3.4.4-cp27-none-win_amd64.whl
The first thing you should do is upgrade pip; the latest version is 8.0. Next, you need to install wheel support (this step may be redundant in later versions) and then finally install your wheel:
pip install --upgrade pip
pip install wheel
lxml needs a lot of source-level dependencies, which are difficult to install in Windows. This is why the project provides binary installers for Windows. You can download these from the pypi page for lxml. Make sure you choose the right version for your environment:
lxml-3.4.4.win32-py2.7.exe - for Python 2.7 running on Windows 32-bit
lxml-3.4.4.win32-py3.2.exe - for Python 3.2 running on Windows 32-bit
lxml-3.4.4.win-amd64-py2.7.exe - for Python 2.7, running on Windows 64-bit
I am trying to install some additional packages that do not come with Anaconda. All of these packages can be installed using pip install PackageName. However, when I type this command at the Anaconda Command Prompt, I get the following error:
Fatal error in launcher: Unable to create process using '"C:\Python27\python.exe
" "C:\python27\scripts\pip.exe" install MechanicalSoup'
I also tried to run the command from the python interpreter after import pip but that also did not work (I got a SyntaxError: invalid syntax).
I am a noob and understand that this might be a very basic question so thanks for your help in advance!
PS: I am using Windows 7, 64 bit, conda version: 3.7.1 and python version: 2.7.6.
When installing anaconda, you are asked if you want to include the installed python to your system PATH variable. Make sure you have it in your PATH. If everything is set up correct, you can run pip from your regular command prompt aswell.
Using #heinzchr's and #mmann's suggestions I was able to piece together the problem. I already had a version of Python 2.7 saved at C:\Python27 and I had to remove this from the Path (My Computer's properties> Advanced system settings> System variables> Path). I can now use pip install from the command line.
There is a way around the use of pip
From the anaconda terminal window you can run:
conda install PackageName
Because MechanicalSoup isn't in one of anaconda's package channels you will have to do a bit of editing
See instructions near the bottom on their blog
For those looking for Python packages not added to current channels in anaconda, try https://conda-forge.org/ For example, if you want to install MechanicalSoup you'll find it at https://anaconda.org/conda-forge/mechanicalsoup and use the -c option to tell conda the channel to use:
conda install -c conda-forge mechanicalsoup
I've found that the Basemap (module for matplotlib and Python) binary installer for Windows cannot detect Python on the system when Python is installed as part of a stack install, like Anaconda or WinPython. The installer exits, rather than allow you to point to the directory of installation.
I have to therefore install via source. However, I don't know the method to do this. The Readme.txt and install instructions don't seem to help. They simply instruct to "install geos-3.3.3 first" - well, how exactly? I don't see a setup.py in that directory.
Any help would be great. (Python 2.7, Win 7, 64b)
I use windows. And my installation failed with official guidance, too.
Finally I installed Basemap using the following method. Although I am not sure if it will go right for you, I just offer mine.
First of all, you must have pip in your computer. (It is much easier
to install, compared with Basemap and other things. And it can be
used to install many useful packages.)
Then go this great link: http://www.lfd.uci.edu/~gohlke/pythonlibs/
And download the file named "basemap‑1.1.0‑cp27‑cp27m‑win32.whl".
Move the .whl file to directory "C:\Python27". (Maybe you
installed your python in different disk, then change it
accordingly.)
Open terminal. (Use cmd or Git Bash or something else.)
Use command:
pip install basemap‑1.1.0‑cp27‑cp27m‑win32.whl
The following worked for me using Python 3.10.1.
Setup environment using terminal in Visual Studio Code (https://code.visualstudio.com/docs/python/python-tutorial):
py -3 -m venv .venv
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope Process
.venv\scripts\activate
Install basemap using pip:
pip install matplotlib
pip install basemap-data
pip install basemap-data-hires
pip install basemap
Create file with code from: https://matplotlib.org/basemap/users/examples.html
Remember to select the correct interpreter (In VSCode use Ctrl+Shift+P to select interpreter).
That's it.
