I'm trying to learn how to use Plotly using VSCode, but the minute I run my code from the terminal, it says ModuleNotFoundError: No module named 'plotly' Any idea why this is happening? Python is installed via Anaconda, and if I try to do pip install plotly it tells me it's already installed. I've tried nearly everything I can find about this issue and nothing works. Any suggestions would be appreciated.
I'll also add that when I do pip install plotly it gives the following:
Requirement already satisfied: plotly in /Users/username/opt/anaconda3/lib/python3.8/site-packages (4.14.3) Requirement already satisfied: retrying>=1.3.3 in /Users/username/opt/anaconda3/lib/python3.8/site-packages (from plotly) (1.3.3) Requirement already satisfied: six in /Users/username/opt/anaconda3/lib/python3.8/site-packages (from plotly) (1.15.0)
It's possible that you have multiple python versions installed and pip installed plotly for the wrong version. Try to do pip --version and in your code (before the plotly import) do
import sys
print(sys.version)
to see if the python versions match. If they don't, you may have to call pip3 install instead.
(Would have posted this as a comment, but don't have enough reputation).
Accidental fix found: I was working with the bash shell on the VS Code terminal. I switched to the zsh shell by doing exec zsh. When I ran the file using the zsh shell, everything worked.

I will come straight to the point. I installed python version 3.8.5 as the latest stable python version but when I use the command python3 in my terminal it makes me use python 3.7.6.
Is there a way to fix this?

Make sure you have added the local of the new version to your PATH variable, and ensure the command s referring to the right file with
python3 —version

I'm trying to create graphs using plotly for the first time. Since I'm currently using Visual Studio Code for my coding (either python scripts or notebooks), I'm currently trying to use plotly in VSC.
I've installed everything from the plotly getting started page (conda installed plotly, notebook, ipywidgets and even jupyter) but I'm still getiing an error when importing.
The thing is, when I've tried importing plotly in a python file in VSC, it's running well. I've also tried running it in a Jupyter Notebook and it's also running.
import plotly.express as px
I'm pretty sure that I've installed everything in the correct environment and I'm using the same environment all throughout.
What do I need to run plotly in a notebook in VSC?
It seems like your python versions/pip versions are different (especially if you're using an env). In Visual studio Code, you can bring up a simple terminal directing to the directory of your project (or env). Just click Terminal > New terminal. This will bring up a terminal (like CMD or terminal) at the bottom of the screen.
From then you can check the version of Pip and python for either your system globally, or the version install in your env. As long as your env is activated, then it will check the versions for the env, not your system.
For macOS:
To show all python installations of your system:
which -a python
To get the version for python 3 (which is what you should be on):
python3 --version
To get the version for pip:
pip -v
For windows:
python3 --version
pip -v
If the versions are incorrect then you can either install the right version of pip in your env or change python paths. First option is recommended.
If you are using macOS. Entering the command which -a python will show a very old Python 2.X version. Do not tamper with this or it's path as it is needed by macOS to run.
Fair Warning: I am extremely new to python, so please excuse any dumb mistakes I make =)
I would like to be able to open/close/manipulate/read Word documents (docx files) on my Mac using Python. The python-docx module looked really useful, so I have been trying to install it on my system, to no avail.
Here's what I've done so far:
Checked that I do indeed have python installed using the python --version command in terminal. I have version 3.7.0, so all good there.
Checked that I do indeed have pip installed - I was able to use pip install and pip uninstall commands, so all good. I also upgraded my pip version using pip install --upgrade pip to pip-19.1.1
Following the online documentation (see here), I tried pip install python-docx. This seemed to work just fine, and after the progress bar loaded all the way I saw:
Successfully built python-docx
twisted 18.7.0 requires PyHamcrest>=1.9.0, which is not installed.
Installing collected packages: python-docx
Successfully installed python-docx-0.8.10
I wasn't completely sure what pyhamcrest was, but I installed it anyway just to be safe using pip install pyhamcrest
As other sites suggested, I also tried to install Pillow, lxml, and python-dateutil using their respective install commands, and in each case saw the Requirement already satisfied: message, with an anaconda path listed.
Frustrated, I also tried easy_install python-docx, the manual version, and even pip install docx . In all cases, when I run IDLE and type from docx import Document or just import docx, I get the following message in the shell:
`Traceback (most recent call last):`
`File "/Users/[my_name]/Desktop/Medical.py", line 3, in <module> `
`import docx`
`ModuleNotFoundError: No module named 'docx'`
Could anyone help point me in the right direction? Thank you very much.
The Anaconda Python distribution has its own system of installation of packages.
After the installation of Anaconda, the variable $PATH has been modified so that anaconda python was the first, and OsX's python in the last position.
If you type "python" in a shell will execute the anaconda python, instead of the standard OsX python (which is 2.7, not 3.x).
Following the instructions of the package python-docx, you have installed it using pip, which is the default method for installing packages, but this method is not valid for Anaconda Python. So, you finished installing python-docx for the python 2.7 of OsX.
To install packages for anaconda, you must run the command
conda install <package>
The python-docx module for anaconda can be found in a separated repository called conda-forge; typing the command
conda install -c conda-forge python-docx
you will install the package and the requested dependencies.
Other useful commands are:
anaconda-navigator for exploring the Anaconda system
anaconda-project for managing projects with anaconda
idle3 for Anaconda Python shell.
Before start coding, run anaconda-navigator and take a look at the 'Learning' section.
For a better experience, I suggest PyCharm IDE for Anaconda from JetBrains.
I have read previous posts on installation issues. Nothing seems to work.
I have Ubuntu 14.04LTS, 32 bit, Anaconda python ver 2.7.
I installed pyephem using sudo pip install pyephem [after checking I have python-dev, and latest pip] Installation said it was successful.
When I run Python 2.7 and try to import ephem, it says Import error:
No Module named _libastro.
Any help will be appreciated.
If you are using Anaconda and have activated your conda environment, you should not need to use sudo — that might aim the install at your system Python, the one governed by the root account and by sudo, instead. You could try activating your conda environment and then just doing conda install ephem because it comes built in to conda, you do not need pip plus a compiler to try installing it!
i am trying to get inline graphs working in iPython notebook.. i begin by starting ipython with the command ipython notebook --pylab inline.
when i try to use the plot() function i get the following error
im running on OSX 10.6.8 and running ipython out of a virtualenv i have matplotlib and libpng installed
i also get this warning in the terminal
libpng warning: Application built with libpng-1.2.41 but running with 1.5.13
and plot() works normally when i use ipython in the terminal only when i use ipython notebook i get this error.. can someone help me with this..?
I had this problem as well. Another solution is to change the format which the notebook will render images in, from 'png' to 'svg'. This can be done in your config file. Mine is located at:
~/.ipython/profile_default/ipython_notebook_config.py
There is a line that looks like this
# c.InlineBackend.figure_format = 'png'
Uncommenting and changing to 'svg' did the trick for me:
c.InlineBackend.figure_format = 'svg'
This recent question on this board is similar to yours: matplotlib and libpng issues with ipython notebook
See if the solution there solves your issue.
so i finally got this working..
first off i had to get all my outdated ports updated
first i did port selfupdate
then sudo port update outdated
after that i reinstalled ipython using mac ports
sudo port install py27-ipython
then i had to install tornado and pyzmq respectively as ipython depends on it
sudo port install py27-tornado
sudo port install py27-zmq
and then ran it from the terminal
ipython notebook --pylab inline
everything works fine now i can plot maps inline in ipython!
i guess the reason it didnt work before was some problems with pip maybe its installing matplotlib that is build only for libpng 1.2.41 ??... so anyways if anyone else faces this problem id suggest reinstalling all the libraries and ipython via mac ports thats the only thing that worked for me.
Since it was complaining that the versions of libpng used for building and for running are different, I have reinstalled the matplotlib by forcing the path to includes.
CFLAGS="`libpng-config --cflags`" pip install matplotlib -I
