I'm setting up a new MacBook and testing the code that I ran on my old Macbook.
One module I need is cartopy. I have installed it using the MacOS instructions detailed here -> https://scitools.org.uk/cartopy/docs/latest/installing.html
This all installs no problem. However when I try to import cartopy I hit the following error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/cartopy/__init__.py", line 107, in <module>

Tried uninstalling proj downgrading to proj7 via homebrew then uninstalling and reinstalling cartopy -> no effect
Tried uninstalling and reinstalling geos via homebrew then uninstalling and reinstalling cartopy -> no effect
Tried uninstalling and reinstalling shapely for versions earlier than 2 then uninstalling and reinstalling cartopy -> no effect
Tried installing cartopy via conda with conda install -c conda-forge cartopy -> this results in a package which I can import but which contains none of the cartopy functions and only basic functions from the "string" package.
My current versions are
cartopy 0.21.0
shapely 1.8.5.post1
geopandas 0.11.1
geos 3.11.0
proj 9.1.0
Has anyone hit this problem before and solved it?
Sorry for asking but I've been stuck on this for ages.
I managed to get cartopy installed via conda but only in the default anaconda environment. That will do but still no idea why I couldn't get it working from pip using the instructions on the cartopy site

So I wanted to import matplotlib to my virtual python version of 3.10.0 (and other versions). I install it as usual:
pip install matplotlib
Everything seems to work, no errors show up with pip. But when I try to run this code snippet in vs code (to see if mpl works):
import matplotlib
print(matplotlib.__version__)
It outputs this:
File "/Users/XYZ/Desktop//pienv.py", line 1, in <module>
import matplotlib
File "/Users/XYZ/Desktop//matplotlib.py", line 1, in <module>
import matplotlib.pyplot as plt
ModuleNotFoundError: No module named 'matplotlib.pyplot'; 'matplotlib' is not a package
But when I do the same in the terminal it outputs the correct version.
It doesn't matter if I have python installed with dmg file or with pyenv, result is the same.
I tried to format operating system to ensure there is no os trash that might be getting in a way. Then I just installed python with pyenv.
I'm using osx 12.0.1
My vscode setup is straightforward, just python extension and python interpreter set to what pyenv has as a local python.
Is there that can be done, or that I'm doing wrong?
Found the answer.
It's just a stupid thing.
Don't name your projects with the names of your libraries when they're in the same directory.
I am using ROS-melodic in ubuntu 18.04 LTS. I am getting this error:
Could not import "pyqt" bindings of qt_gui_cpp library - so C++ plugins will not be available:
Traceback (most recent call last):
File "/opt/ros/melodic/lib/python2.7/dist-packages/qt_gui_cpp/cpp_binding_helper.py", line 43, in <module>
from . import libqt_gui_cpp_sip
ImportError: dynamic module does not define module export function (PyInit_libqt_gui_cpp_sip)
however I have installed pyqt5 and pydot manually, rqt_graph shows up but with this warning. I want to know what can I do to get it right? Is this going to be problem in future? Now rqt_graph is loading but I don't know if this will mess up/create lacking in the graph?
Try uninstalling double packages if any using
pip3 uninstall PyQt5-sip PyQt5
Then try importing it in python3 to check if any other version is there.
If the import is successful then try running the command again
rosrun rqt_graph rqt_graph
if still some error exists install
pip3 install PyQt5==5.12
I'm trying to change table wrote by me on tkinter with the pandastable one in order to do the handling of data directly from a pandas.DataFrame.
But despite I have already installed Anaconda3 with matlplotlib, numpy, pandas ect. modules when i would like to import pandastable I have trouble.
This is the problem:
import pandastable
Traceback (most recent call last):
File "<pyshell#8>", line 1, in <module>
import pandastable
ImportError: No module named 'pandastable'
pip install pandastable
Requires python>=3.3 or 2.7 and numpy, matplotlib and pandas.
See: pandastable on github
edit: You may have multiple Python environments installed on your machine. Anaconda uses conda install to keep things in check but pandastable doesn't seem to be available through Anaconda packages. Make sure you are installing to the same Python environment that your script uses. You might also try:
pip3 install pandastable
I'm interested in trying out sympy with Blender (v2.76, Python 3.4.2 Console, Windows 8.1). I followed this answer from Blender SE, downloaded sympy as a ZIP from Githib, and moved the sympy folder to C:\Program Files\Blender Foundation\Blender\2.76\python\lib\site-packages. However, when I opened Blender and tried to import sympy in the Python Console, I got the following error:
>>> import sympy
Traceback (most recent call last):
File "<blender_console>", line 1, in <module>
File "C:\Program Files\Blender Foundation\Blender\2.76\python\lib\site-packages\sympy\__init__.py", line 20, in <module>
raise ImportError("SymPy now depends on mpmath as an external library. "
ImportError: SymPy now depends on mpmath as an external library. See http://docs.sympy.org/latest/install.html#mpmath for more information.
I don't know how to install an external library. I tried going to the link mentioned in the ImportError, and I saw pip install mpmath. I tried it in cmd, but got this:
>pip install mpmath
Requirement already satisfied (use --upgrade to upgrade): mpmath in c:\anaconda3
\lib\site-packages
I did install Anaconda a while ago, so I guess it makes sense to have this output. How can I install mpmath as an external library for Blender so I can import sympy in it?
You want to install mpmath into blenders python folder, the same as you have done for sympy.
Your example of running pip was done in a system installed python that is setup to find the mpmath that you have installed in c:\anaconda3\lib\site-packages
Another option is to use the existing install of mpmath and sympy by adding your existing path to sys.path or adding it to the PYTHONPATH environment variable before you start blender.
I have a problem similar to this one below:
Python pip broken after OS X 10.8 upgrade
After installing ML, I can no longer use iPython, SciPy or Matplotlib. I get this error:
Shanes-MacBook-Pro:~ $ ipython
Traceback (most recent call last):
File "/usr/local/bin/ipython", line 5, in <module>
from pkg_resources import load_entry_point
File "/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/pkg_resources.py", line 2603, in <module>

raise DistributionNotFound(req) # XXX put more info here
pkg_resources.DistributionNotFound: ipython==0.14.dev
I have tried the following to fix it:
Using sudo ipython
Installing latest Xcode
Reinstalling SciPy superpack
When I type which python it says it is in /usr/bin/python.
Extra information:
nside /Library/python/2.7/site-packages
Inside there is the following:
DateUtils-0.5.2-py2.7.egg
README
easy-install.pth
nose-1.1.2-py2.7.egg
pika-0.9.5-py2.7.egg
pyzmq-2.2.0.1-py2.7-macosx-10.8-intel.egg
tornado-2.3-py2.7.egg
So with this ML upgrade, it removed my numpy, ipython, etc. And it does not install there anymore like it did with lion. How can I find where it installs too because it seems like it is working when I run the install_superpack shell script.
As an update, I never fixed this specific problem. However, I just downloaded the iPython, SciPy, Matplotlib etc. from Enthought. I answered someone elses question on how to do this here:
How to check whether I have IPython installed on my machine and what sequence to install these libraries?
