I found this script (tutorial) on GitHub (https://github.com/amyoshino/Dash_Tutorial_Series/blob/master/ex4.py) and I am trying to run in my local machine.
Unfortunately I am having and Error
I would really appreciate if anyone can help me to run this script.
Perhaps this is something easy but I am new in coding.
Thank you!
You probably just need to pip install the dash-core-components library!
Take a look at the Dash Installation documentation. It currently recommends running these commands:
pip install dash==0.38.0 # The core dash backend
pip install dash-html-components==0.13.5 # HTML components
pip install dash-core-components==0.43.1 # Supercharged components
pip install dash-table==3.5.0 # Interactive DataTable component (new!)
pip install dash-daq==0.1.0 # DAQ components (newly open-sourced!)
For more info on using pip to install Python packages, see: Installing Packages.
If you have run those commands, and Flask still throws that error, you may be having a path/environment issue, and should provide more info in your question about your Python setup.
Also, just to give you a sense of how to interpret this error message:
It's often easiest to start at the bottom and work your way up.
Here, the bottommost message is a FileNotFound error.
The program is looking for the file in your Python37/lib/site-packages folder. That tells you it's looking for a Python package. That is the directory to which Python packages get installed when you use a tool like pip.

I have been using python in VS Code for a while, everything was smooth. But yesterday I accidentally pressed "Run CC Cleaner" on my PC. This, among other things must have cleared some VS Code cache and I no longer can run scripts.
In cmd for example it says that "pandas can not be found" while pip says that it definitely is installed.
Running !python - m pip install pandas in VS Code just does not do anything.
Something must have severed the connection between python and VS Code.
The Python and the Python Extension do not have some connections, the Python Extension just needs to find the path of the Python.
It looks like an environment problem. Could you check which pip you are using with the command of pip --version?
But I was confusing of python - m pip install pandas in VS Code just does not do anything, could you explain it clearly?
I'm trying to import https://github.com/chrisconlan/algorithmic-trading-with-python in my code. I've never imported anything from GitHub before and have looked at various other questions that have been asked on Stack Overflow regarding this problem but it just doesn't work. When I try to run the 'portfolio.py' code for example I keep getting a ModuleNotFound error for 'pypm'. What exactly is the correct way to import such a module or the whole GitHub directory?
I'm working with Visual Studio Code on Windows.
You will need to pip install the module. In your case the command you would need to run is python -m pip install -U git+https://github.com/chrisconlan/algorithmic-trading-with-python. Once you have done that you need to find the name of the module. You can do this with pip list. Find the name of the module you just installed.
Then you just stick import <module name> at the top of your code with the rest of your imports.
What i used to do in this is to clone the repository on the folder where are installed the python's packages. This is useful when you do not want to use the pip cmd tool, keeping the pip's cache memory under control.
I received an error on atom, it asked to install ipkernal using pip.
Not sure what to do. I have Anaconda on my system and not pip. Can someone explains whats the error about and how can I solve it in using anaconda.
I was running a python code and saved the file as .py.
import pandas as pd
wd = pd.read_csv("winequality-red", sep = ";")
five = wd.head()
print ("five")
Error message:
No kernel for grammar Python found <br>
Check that the language for this file is set in Atom and that you have a Jupyter kernel installed for it.<br>
To detect your current Python install you will need to run:<br>
python -m pip install ipykernel<br>
python -m ipykernel install --user
This isn't really an answer, but you might have better luck on the dedicated Atom forums.
In your case though, it looks like you haven't installed the proper kernels Hydrogen needs to run Python with. (Of course, I'm just assuming you're using Hydrogen. You haven't actually provided any details about how you are trying to run it).
From the Hydrogen documentation, it takes you to this page for Python kernels.

In particular, I think you want to run the command conda install ipykernel
Problem:
I'd like to install Pmw 2.0.0 (project page here) so that I can use it with tkinter in python3. The setup script from the package detects which version of python you're using and installs the version that is appropriate for your system (Ubuntu 15 in my case). I can't find any references to switches to make it install the 2.0.0 instead of 1.3.3(the Python 2.7 version), nor have I been able to get the script to install to the python3 libraries.
What I've done so far:
I've changed the python version detector in the setup script from
if sys.version_info[0]<3:
version='2.0.0' # really '1.3.3'
packages=['Pmw', 'Pmw.Pmw_1_3_3', 'Pmw.Pmw_1_3_3.lib',]
to
if sys.version_info[0]<2:
version='2.0.0' # really '1.3.3'
packages=['Pmw', 'Pmw.Pmw_1_3_3', 'Pmw.Pmw_1_3_3.lib',]
to attempt to force the installer to default to the python3 version, which it does, but it installs them in the python2.7 libraries (/usr/local/lib/python2.7/distpackages).
What I want to do:
I'm looking for a way to force the installer to put the 3.4-compatible package into the python3 libraries. If that means getting it to install both packages in their respective correct directories, that's fine, too. I'm stumped about what to try next.
Answered by RazZiel on AskUbuntu:
Link here.
Instead of using the command sudo python setup.py build and then sudo python setup.py install, I should have been using python3 to execute the setup script. I've managed to outthink myself pretty badly on this one.
I encountered a problem after I finished all process of installing TurboGear2 on my OS X 10.8.2.
Using Python2.7, TurboGear2.2.0
The installing process was based on tutorial of official website: http://www.turbogears.org/2.2/docs/main/DownloadInstall.html
Problem describing:
1. Follow the tutorial, installation went smoothly until nosetests show 10 ERRORs.
2. Then, "paster setup-app development.ini" also show error messages as below:
But I command "paster serve development.ini" in terminal, the server still successfully work.
I think there're some problems, but I found no answers.
Do anyone have any idea about this?
Thanks a lot.
Yeah unfortunatly that's a problem with the new version of sqlalchemy... just remove the version of sqlalchemy pip uninstall sqlalchemy and install the 0.7.9 version pip install sqlalchemy==0.7.9
