How to update spyder standalone application - spyder

How can i update spyder using CMD. I have decided to use Spyder standalone and I am not using Anaconda, as I don't need the rest of the package. No i need to update it, but I can't find the option.

Got it, it's:
pip install -u spyder

spyder showing missing dependencies

Just wondering if this is a spyder bug, or whether there was an update between yesterday and today? spyder was working fine for me yesterday. This error message showed up.
jedi=0.17.1: 0.18.0 (NOK)
parso=0.7.0: 0.8.2 (NOK)
Somewhat related, what do jedi and parso do, and what does "NOK" mean?
(Spyder maintainer here) My answers to your questions:

This is not a bug. It means that you have the wrong versions of some of our dependencies (as the message clearly states).
spyder was working fine for me yesterday
You probably ran conda update --all, or installed another package with conda or pip, which updated Jedi and Parso as well.
To fix this problem, you need to reinstall those packages with the right versions. For that, please open the Anaconda Prompt or a system terminal (i.e. cmd.exe) and run one of the following commands:
conda install jedi=0.17 parso=0.7
if you're using Anaconda, or
pip install jedi==0.17.1 parso==0.7.0
if not.
somewhat related, what do jedi and parso do, and what does "NOK" mean?
Jedi provides code completion in the editor and Parso is used for code folding on it as well.
NOK means Not ok.

How to install luarocks for Windows 10

So I've been searching everywhere and I'm completely stuck right now. Initially I just installed the binaries which came with luarocks.exe and luarocks_admin.exe but with that there was no config file so when I go to install the luarocks-mysql module, luarocks was unable to find the lua library and said I needed to set the LUA_LIBDIR variable in the config. I can't make changes to the luarocks config though because it either doesn't exist or I can't find it.
After getting this problem I went back to install the luarocks all in one package but I'm unable to follow the instructions because I can't find the install.bat file that they were talking about. Sorry if this is a lot but I'm just running into a bunch of problems right now.
EDIT: Just use Ubuntu, it's 100 times easier.
I had similar problems. I didn't look for a solution and just installed wsl on windows 10.

Then execute the commands in the console:
sudo apt install lua5.3 liblua5.3-0 liblua5.3-dev
sudo apt install luarocks

Installing OpenCV into PyCharm

Idk if this is a stackoverflow-appropriate post so forgive if the question is misplaced. I'm trying to install OpenCV into my Pycharm IDE through the conda virtual environment. I typed conda install -c conda-forge opencv inside the PyCharm terminal and it has been doing this for 11 hours and God knows how many more to go.
Pycharm did this with PyTorch as well. Am I doing something wrong or is this normal?
While you can install packages directly in PyCharm by going to file->settings select Project Interpreter and click on the '+' icon on the top right (see image)
I would recommend creating a requirements.txt file in the root of your project, and write down all your required packages. When a package is missing, PyCharm will automatically suggest to install the package for you.
e.g. for installing opencv you can add the following to you requirements.txt
opencv-python
Or even specify the version that your project needs
opencv-python==4.1.2
edit: the advantage of using a requirement.txt is that you can more easily port the project to another machine, and re-install the packages if needed.

How To Update Spyder 3.3.0

I currently use Spyder 3.2.8 with Anaconda/Miniconda. When I open the Spyder editor, a Spyder update window pops up and shows Spyder 3.3.0 is available. It also indicates that "please wait until new conda packages are available and use conda to perform the update".
I followed the direction using anaconda prompt to update. My computer shows the packages were already installed successfully. However, my Spyder Editor is still the version 3.2.8 I also used Anaconda Navigator to update by clicking on the "gear" but no luck. How can I update from Spyder 3.2.8 to 3.3.0? Thank you!!!!
The only thing which really did the trick is
conda install spyder=3.3.0
so in this case you have to explicitly provide the package version.
I have a clean anaconda 5.2.0 installation.
Update: after that i can "conda update spyder" and everything is consistent (for 3.3.1 and further versions)
(Spyder maintainer here) If you already tried to update (either through Navigator or in a system terminal) and you didn't get a new version, that means that conda packages are still unavailable and you have to wait a couple more days to perform the update.
You can get it from conda-forge:
conda install -c conda-forge spyder
https://anaconda.org/anaconda/spyder
As you can see in that internet address, there is only 3.3.0 version for linux and osx.
I think that 3.3.0 version for window would be a little late.

How to start spyder after macports installation

this is my first question to post.
I am working with python at the moment (on mac os 10.6.8), and have struggled for the lack of an ide. I have been using a version of emacs that offers syntax highlighting, but does not offer the ability to browse variable values without print statements. What I was looking for was the equivalent of eclipse, which basically died on my machine when I upgraded from 10.4.11 to 10.6.8. I've not been successful resurrecting it. Time to move on.
My graduate advisor suggested spyder, and last night I bit the bullet, installing macports and (apparently) spyder, successfully.
The problem I'm having is HOW do I start spyder once installed. Apparently, python spyder.py is not the approach to use. Elsewhere (not here) I saw a post that suggested that there was supposed to be a batch executable that I should be able to find by typing
which spyder
This yielded nothing.
The spyder documentation (located at http://packages.python.org/spyder/options.html) suggests that the command
python spyder.py
is the way to go. Here is the result:
Bobs-Machine:spyderlib robertlilly$ python spyder.py
Traceback (most recent call last):
File "spyder.py", line 31, in
from spyderlib import qt #analysis:ignore
ImportError: No module named spyderlib
Most of my searches here have just pointed out that one should use MacPorts for the install, nothing after that. The readme included the macports spyder install, I thought, didn't provide sufficient direction.
If anybody knows where to look, that would be great.
Regards,
Robert
For me, I installed the macports package py37-spyder. In /opt/local/bin there is the package there, spyder-3.7. Launching that works already. In order to make that the default, I have to run
sudo port select --set spyder spyder-37
Then I can run it directly as
spyder from Terminal. If you want to see which versions of spyder are available on your system, then
port select --list spyder
will tell you the versions you have.
Macports should install a spyder binary to /opt/local/bin/spyder, or thereabouts. If you already have /opt/local/bin/ in your PATH variable, then just run:
$ spyder &
Or more explicitly:
$ /opt/local/bin/spyder &
...if you don't have the PATH setup. Hope that helps.
I just recently installed spyder via MacPorts.
(the command I chose was sudo port install py27-spyder, which installed Spyder v.2.2.3 on Mac OS 10.7.5 & Python 2.7.5)
At the end of the Spyder installation, the terminal showed "use command spyder to launch" (or something to that effect)
So, for me, I simply had to type spyder into a terminal to launch it. Your error referring to missing spyderlib might mean that your spyder installation did not in fact complete properly. (I have found it's not uncommon to have to track down 2-3 weird bugs and dependencies for complex MacPorts installs).
If you find it did complete properly, then perhaps the MacPorts directory was not added to your PATH. It you open ~/.profile, you should seen that MacPorts added it's directory to the shell's search path. Here's what the MacPorts installer added to my .profile:
# MacPorts Installer addition on 2012-11-19_at_17:16:31: adding an appropriate PATH variable fo$
export PATH=/opt/local/bin:/opt/local/sbin:$PATH
# Finished adapting your PATH environment variable for use with MacPorts.
To make a Mac OS-friendly icon to launch Spyder, I then made a new text file (I did it with Terminal.app>pico) containing the following text:
#!/bin/bash
spyder
and saved the file as spyder.command. This file is now double-clickable and will launch Spyder (and an alias to it can have a more normal name like "Launch Spyder"). Throw it into the /Applications folder & make an Icon for it via /Utilities/Icon Composer.app (grab the Spyder icon on the website) and it's like a Pythonic Matlab!
