Using Tcl with Jupyter notebook - tcl

I downloaded Anaconda, and have been using Jupyter notebook. Now I would like to use it with Tcl. I followed the instructions at https://github.com/rpep/tcl_kernel, (which is to pip3 install tcl_kernel).
It has installed in AppData\Local\Programs\Python\Python36-32.
However, Tcl does not appear as an option for a new notebook.
Can anyone advise?
Thankyou.

Installing Tcl on Jupyter Notebook: intel offers a package to be used on Jupyter Notebook, where you can develop your projects and view the result of the codes.
To perform the installation (linux), type the following command in the terminal:
conda install -c intel tcl
pip3 install tcl_kernel
python3 -m tcl_kernel.install
conda update conda
Link of the pages so that you can search for the equivalent packages on Win / Mac:
https://anaconda.org/intel/tcl
https://github.com/rpep/tcl_kernel
Ready! When accessing Jupyter Notebook, select the Tcl option in the 'New' section.
There are versions for various Operating Systems. I chose Linux because it is the only one on computers here at home.

I don't see that kernel listed under 'new' -- but if I open another notebook and try the 'kernel' menu, there is a 'change kernel' item that does the job.

I'm having issues getting pygame to work as I don't understand how to assign path [duplicate]

I have installed python 3.3.2 and pygame 1.9.2a0. Whenever I try to import pygame by typing:
import pygame
I get following error message :
Python 3.3.2 (v3.3.2:d047928ae3f6, May 16 2013, 00:03:43) [MSC v.1600 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import pygame
Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
import pygame
ImportError: No module named 'pygame'
>>>
I went through some of the questions related to this error but none of the solution helped.
I have 64 bit machine with Win7 OS
go to python/scripts folder, open a command window to this path, type the
following:
C:\python34\scripts> python -m pip install pygame
To test it, open python IDE and type
import pygame
print (pygame.ver)
It worked for me...
Here are instructions for users with the newer Python 3.5 (Google brought me here, I suspect other 3.5 users might end up here as well):
I just successfully installed Pygame 1.9.2a0-cp35 on Windows and it runs with Python 3.5.1.
Install Python, and remember the install location
Go here and download pygame-1.9.2a0-cp35-none-win32.whl
Move the downloaded .whl file to your python35/Scripts directory
Open a command prompt in the Scripts directory (Shift-Right click in the directory > Open a command window here)
Enter the command:
pip3 install pygame-1.9.2a0-cp35-none-win32.whl
If you get an error in the last step, try:
python -m pip install pygame-1.9.2a0-cp35-none-win32.whl
And that should do it. Tested as working on Windows 10 64bit.
I was trying to figure this out for at least an hour. And you're right the problem is that the installation files are all for 32 bit.
Luckily I found a link to the 64 pygame download! Here it is: http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame
Just pick the corresponding version according to your python version and it should work like magic. The installation feature will bring you to a bright-blue screen as the installation (at this point you know that the installation is correct for you.
Then go into the Python IDLE and type "import pygame" and you should not get any more errors.
Props go to #yuvi who shared the link with StackOverflow.
open the folder where your python is installed
open scripts folder
type cmd in the address bar. It opens a command prompt window in that location
type pip install pygame and press enter
it should download and install pygame module
now run your code. It works fine :-)
I had the same problem and discovered that Pygame doesn't work for Python3 at least on the Mac OS, but I also have Tython2 installed in my computer as you probably do too, so when I use Pygame, I switch the path so that it uses python2 instead of python3. I use Sublime Text as my text editor so I just go to
Tools > Build Systems > New Build System and enter the following:
{
"cmd": ["/usr/local/bin/python", "-u", "$file"],
}
instead of
{
"cmd": ["/usr/local/bin/python3", "-u", "$file"],
}
in my case. And when I'm not using pygame, I simply change the path back so that I can use Python3.
The current PyGame release, 1.9.6 doesn't support Python 3.9. I fyou don't want to wait for PyGame 2.0, you have to use Python 3.8. Alternatively, you can install a developer version by explicitly specifying the version (2.0.0.dev20 is the latest release at the time of writing):
pip install pygame==2.0.0.dev20
or try to install a pre-release version by enabling the --pre option:
pip install pygame --pre
Resolved !
Here is an example
C:\Users\user\AppData\Local\Programs\Python\Python36-32\Scripts>pip install pygame
try this in your command prompt:
python -m pip install pygame
I was getting the same error. It is because your version of Pygame is not compatible with your version of Python or Pydev. Go to this link and get the proper version of Pygame for your current version of Python. Ctrl F to find it faster or click on the word python in blue. up at the top. While you instal Pygame it should find the Python path by itself. At least mind did any ways. I run Pygame through Eclipse with Python 3.4.

Since no answer stated this:
Make sure that, if you are using a virtual environment, you have activated it before trying to run the program.
If you don't really know if you are using a virtual environment or not, check with the other contributors of the project. Or maybe try to find a file with the name activate like this: find . -name activate.
Install and download pygame .whl file.
Move .whl file to your python35/Scripts
Go to cmd
Change directory to python scripts
Type:
pip install pygame
Here is an example:
C:\Users\user\AppData\Local\Programs\Python\Python36-32\Scripts>pip install pygame
I just encountered the same problem and found that I am having multiple interpreters of the different versions installed in my system and pygame got installed in one of them when I installed it using command but in my IDE another interpreter was selected so this messed up my system, try to see if you are also having the same situation.
Just use this command in the terminal python3 -m pip install -U pygame --user
I am a quite newbie to python and I was having same issue. (windows x64 os)
I have solved, doing below steps
I removed python (x64 version) and pygame
I have downloaded and installed python 2.6.6 x86: https://www.python.org/ftp/python/2.6.6/python-2.6.6.msi
I have downloaded and installed pygame (when installing, I have chosen the directory that I installed python): http://pygame.org/ftp/pygame-1.9.1.win32-py2.6.msi
Works well :)
You don't need 64 bit Python on Win64 system, just install the 32bit versions of both Python and Pygame and they will work just fine (and there is a ton more modules for them anyways).
I’m using the PyCharm IDE. I could get Pygame to work with IDLE but not with PyCharm. This video helped me install Pygame through PyCharm.
https://youtu.be/HJ9bTO5yYw0
(It seems that PyCharm only recognizes a package; if you use its GUI.)
However, there were a few slight differences for me; because I’m using Windows instead of a Mac.
My “preferences” menu is found in: File->Settings…
Then, in the next screen, I expanded my project menu, and clicked Project Interpreter. Then I clicked the green plus icon to the right to get to the Available Packages screen.
I ran into the error a few days ago! Thankfully, I found the answer.
You see, the problem is that pygame comes in a .whl (wheel) file/package. So, as a result, you have to pip install it.
Pip installing is a very tricky process, so please be careful. The steps are:-
Step1. Go to C:/Python (whatever version you are using)/Scripts. Scroll down. If you see a file named pip.exe, then that means that you are in the right folder. Copy the path.
Step2. In your computer, search for Environment Variables. You should see an option labeled 'Edit the System Environment Variables'. Click on it.
Step3. There, you should see a dialogue box appear. Click 'Environment Variables'. Click on 'Path'. Then, click 'New'. Paste the path that you copies earlier.
Step4. Click 'Ok'.
Step5. Shift + Right Click wherever your pygame is installed. Select 'Open Command Window Here' from the dropdown menu. Type in 'pip install py' then click tab and the full file name should fill in. Then, press Enter, and you're ready to go! Now you shouldn't get the error again!!!
First execute python3 then type the command import pygame,now you can see the output
For this you have to install pygame package from the cmd (on Windows) or from terminal (on mac). Just type pip install pygame
.If it doesn't work for you, then try using this statement pip3 install pygame .
If it is still showing an error then you don't have pip installed on your device and try installing pip first.
make sure if you are on windows that your library directory is added to path
This may happen when pygame didn't installed, install the pygame first
pip
pip install pygame
if dont work update the PIP by goto python install folder and type
python -m pip install --upgrade pip
hope it work
Try this solution:
Type in to cmd (Windows):
C:\Users\'Your name'> pip install -U pygame
You should remove python -m, py -m, python3 -m before the pip
Also remove --user behind it.
It will said:
C:\Users\viait>pip install -U pygame

You gotta use Pycharm and install it in Terminal using pip install pygame and also after that enter Pycharm and hover on pygame in the "Import pygame" and in Pycharm it will tell you to download that and you can easily download it and enjoy your result

How to install Google Apis Drive v3 via command line on Ubuntu-18.04

I have been trying to install Install-Package Google.Apis.Drive.v3 using this source with the difference that I have Ubuntu-18.04 instead of Windows.
I know it may be a simple question but I have been trying research how to do that from this morning. I installed sudo apt install nuget on my machine and have been trying to add packages or as in this case the Google.Apis.Drive.v3 package but no luck.
I went through this source which was useful, but does not carry information I was able to replicate on my Linux machine.
Also this source, this one and this one too. But also this last one is for Windows and was not very useful.
How do I install Google Apis Drive V3 via command line easily as it is documented for windows but on Ubunbtu-18.04?
Thanks for pointing to the right direction for solving this problem.
Solution
The way you install your Drive API's library is depending on the programming language you are aiming to use. These are the following commands to run depending on the different languages to interact with the API (with their respective links to the source of the setup):
Python:
pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib
C#/.NET:
Create a new Visual C# Console Application project in Visual Studio.
Open the NuGet Package Manager Console, select the package source nuget.org, and run the following command:
">Install-Package Google.Apis.Drive.v3
Java:
gradle init --type basic
mkdir -p src/main/java src/main/resources
Node.js:
npm install googleapis#39 --save
For the Browser check out the steps to follow here
I hope this has helped you. Let me know if you need anything else or if you did not understood something.
NOTE: For all Ubuntu-18.04 users that wish to install via command line the correct way is: sudo dotnet add package Google.Apis.Drive.v3

ModuleNotFoundError: No module named 'pyarrow' with satisfied requirements

I am trying to run this command in Jupyter Notebook: import pyarrow, get the same error: "ModuleNotFoundError: No module named 'pyarrow'
I have installed it already with pip3 and brew also. So when I ran pip3install pyarrow it says requirements are already satisfied. All other libraries I have installed runs with no issues from the same directory.
Thank you.
This is an odd one, for sure. I am not familiar enough with pyarrow to know why the following worked.
From the docs, If I do pip3 install pyarrow and run pip3 list, pyarrow shows up in the list but I cannot seem to import it from the python CLI. Yet, if I also run conda install -c conda-forge pyarrow, installing all of it's dependencies, now jupyter notebook can import it properly.
Are you using a venv? Try running jupyter kernelspec list in your console and make sure your kernel is running in the environment you're expecting it to be.

How to installing Pygame for Python 3.5 via pip?

I'm trying to install Pygame for python 3.5 32bit. I have learned that I can open the .whl files provided on the site by using the pip command. The problem is I've tried multiple ways doing this but with constant error.
python -m pip install pygame-1.9.2a0-cp35-none-win32.whl
'python' is not recognized as an internal or external command,
operable program or batch file.
The file I'm trying to install: pygame-1.9.2a0-cp35-none-win32.whl
My python program is located in my programs folder and everything else works fine.
You need to add python.exe to your Windows PATH variable.
The is the system variable that the operating system uses to locate the needed executables from the command line or Terminal windows. [1]
Actually there are many methods to set the PATH variable on windows. One way is to type
set PATH=%PATH%;location path of Python.exe
into the windows command-line interpreter (cmd):
set PATH=%PATH%;C:\Python35-32
Now -- before running the pip command -- you need to make sure that either
your working directory is set to the same folder where your pygame-1. ... in32.whl file is located
or
you supply the full absolute or relative path to the pip command.
Now you should be able to run your python -m pip command after restarting the cmd.exe.
if you get trouble when install pygame error about missing visual studio 10+. I have the answer: the problem is not about have or not have visual studio, because I try many version but it not work. The problem is file: between tar.gz and .whl so, this is the solution:
1) download file:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#pygame go here and download your pygame version, notice about x64 or x86 and python version. my system is x64 and python is 3.4 so I choose: pygame-1.9.2a0-cp34-none-win_amd64.whl
2) put it in some where to install:
I put it in "C:", so open cmd: and type: cd C:\ (this changes the location to C:)
3) install
pip install C:\pygame-1.9.2a0-cp34-none-win_amd64.whl
done !
