I'm running on a Mac, and I'm trying to get CDAT downloaded to use with Python (and the Anaconda package I have downloaded). I try following along with online sources to set it up, but nothing seems to really help. Can anyone offer any assistance?
I successfully downloaded CDAT_lite and can use to with Python/Anaconda, but the with it is that when I try importing modules cdms2 and regrid2, I got an error message stating that the "image not found"
ImportError: dlopen(/Users/name/anaconda/lib/python2.7/site-packages/cdat_lite-6.0rc2-py2.7-macosx-10.5-x86_64.egg/cdtime.so, 2): Library not loaded: libnetcdf.7.dylib
Referenced from: /Users/name/anaconda/lib/python2.7/site-packages/cdat_lite-6.0rc2-py2.7-macosx-10.5-x86_64.egg/cdtime.so
Reason: image not found
Any help is much appreciated! I'm completely lost and have no idea how to proceed
It looks like there is trouble loading the netCDF libraries.
You need to have the latest release of UV-CDAT (which includes the CDAT libraries). Instructions on how to install them are here: https://github.com/UV-CDAT/uvcdat/wiki/Installation-on-Mac.
Hi this seems to be a rather old version. Please try using our latest version at: http://uvcdat.llnl.gov
Install instructions are at: http://uvcdat.llnl.gov/installing.html
You can either build from source: https://github.com/UV-CDAT/uvcdat/wiki/Build
or simply download the binaries: https://github.com/UV-CDAT/uvcdat/wiki/install
Make sure to read the pre-requisites page first ;)

I am running Eclipse IDE 4.20.0 with a PyDev Interpreter on Windows10. I am trying try to get [Camelot][1] to run within my script but continue to get the error-
"Original error was: No module named 'numpy.core._multiarray_umath'"
For each, I have used pip install to install camelot, tabula-py, numpy, pandas, etc. and all of them seemed to install appropriately. My Eclipse Project Properties PYTHONPATH is pointed to the install location and I haven't had issues with other libraries I have installed previously.
The Python version is: Python3.7
The NumPy version is: "1.21.5"
I also tried reverting numpy to an older version (1.15.1) but had no success there based on other posts that I have seen here on stackoverflow. Additionally, I have read the numpy support site that is listed in the error below but can't find anything that would be of note in my system as an issue...
Ultimately, I am attempting to read tables from a PDF in python but it seems that the libraries available (camelot, tabula, etc.) all give me the same issue with numpy. Any suggestions here would be greatly appreciated.
The full error that I am getting is -
ImportError:
IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!
Importing the numpy C-extensions failed.
This error can happen for many reasons, often due to issues with your setup or how NumPy was installed.
We have compiled some common reasons and troubleshooting tips at:
https://numpy.org/devdocs/user/troubleshooting-importerror.html
Please note and check the following:
The Python version is: Python3.7 from "C:\Users~~~\PythonSoftwareFoundation.Python.3.7_qbz5n2kfra8p0\python.exe"
The NumPy version is: "1.21.5"
and make sure that they are the versions you expect.
Please carefully study the documentation linked above for further help.
Original error was: No module named 'numpy.core._multiarray_umath'
Trying to access the todoist api, and I copied some code from the api documentation. However, on my system I get an error stating:
Unable to import 'todoist.api'pylint(import-error).
I installed it with:
pip install todoist-python
as mentioned in the documentation
from todoist.api import TodoistAPI
I get my error on the very first line. How do I not get this?
You did everything right, so it's probably related to the way your installation is set.
Be sure you are using the same python you used to install the library. Check if the library is installed (pip list) and check if you're using the right Python when running the code. It's possible that the library was installed in one version and you're using the other.
I had the same problem, I solved it by following the GitHub instructions, but the name of the module to install using pip is todoist.
RDKit could be a nice package if it wasn't so complicated to install.
Here on SO, there are several questions having problems with the installation of RDKit.
However, on different operating systems or different environments.
My configuration is:
Win10, Python 3.7.4, pip is installed, PATH is set, PYTHONPATH is set.
The installation of other modules is working fine via python -m pip install <package>.
I'm aware that the site recommends the fastest installation with Anaconda.
However, I don't have and don't want Anaconda.
On the webpage it says:
"Get the appropriate windows binary build from: https://github.com/rdkit/rdkit/releases".
However, there are no binaries of the latest versions.
This means, I would have to build it from source. I'm hesitating because the process seems to be pretty complicated, many extra installations with new problems and unknowns, and furthermore, the instructions seem to be outdated and incomplete for somebody who would build binaries from the source for the first time.
So, then I tried some unofficial binaries of RDKit.
If I unpack them and set the paths according to instructions, I get this error message:
>>> from rdkit import Chem
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\xyz\Programs\RDKit\rdkit\__init__.py", line 2, in <module>
from .rdBase import rdkitVersion as __version__
ImportError: DLL load failed: The specified module could not be found.
So, finally my questions:
How to properly install RDKit with the above mentioned configuration?
What is the specified DLL which is missing?
Where is it expecting it and searching it?
Are these RDKit 3.6 binaries maybe incompatible with Python 3.7.4?
I'm pretty sure it is probably a "small" thing (a path here or a check there), but I'm stuck. Thank you for any hints.
Update:
Apparently, it is not just a "small" thing. Chances to get this to work are most likely very low.
In the meantime I found this:
https://github.com/rdkit/rdkit/issues/1812
https://github.com/rdkit/rdkit/issues/2389
If the author of rdkit writes (April 2019):
I would be happy to be able to do pip distributions of the RDKit, but
to the best of my knowledge no one has managed to figure out how to
make it actually work.
I'd be happy to accept a PR from someone who has figured this out, but
I am not likely to have the time to do this myself anytime in the near
future.
So, if anybody feels capable achieving this, please feel free.
I will invest time in something else or will have to switch to Anaconda if I want to use RDKit.
On the webpage you linked there is a section about missing DLLs:
"In Win7 systems, you may run into trouble due to missing DLLs, see one thread from the mailing list: http://www.mail-archive.com/rdkit-discuss#lists.sourceforge.net/msg01632.html You can download the missing DLLs from here: http://www.microsoft.com/en-us/download/details.aspx?id=5555"
Not sure if this helps
I've installed mesos 0.26 successfully on a vm machine.
The installation has been performed on an ubuntu trusty thar system
by following this manual:
https://open.mesosphere.com/getting-started/install/
So far so good. I wanted to write a tiny python framwork.
For this I need to install the eggs via easy_install:
(I've downloaded the eggs accordingly for the trusty thar ubuntu and the 0.26 mesos):
wget http://downloads.mesosphere.io/master/ubuntu/14.04/mesos-0.26.0-py2.7-linux-x86_64.egg
easy_install mesos-0.26.0-py2.7-linux-x86_64.egg
all went fine, however, if I start python in the shell
and type in
import mesos.interface
I get the message: ImportError: No module named interface
As someone suggested, it may be that there is no longer a binding for python, or that they have renamed the API calls. Well, I looked in the version updates here:
http://mesos.apache.org/documentation/latest/upgrades/
Since the transition from 0.19.x to 0.20.x there hasn't been any changes regarding the mesos.interface part, or at least they are not mentioning it here.
To increase the confusion I also get the following error message when I'm typing in python: import mesos.native
There I receive: ImportError: No module named interface.mesos_pb2. To put it into a nutshell: what is going wrong here, and how can it be fixed? And yes, I've googled various web pages, with terms such as "mesos python bindings", mesos +api +python, etc. And yes, I have also consulted the official mesos webpage. There are nice refences for Java and C++ but not for python, or at least they are very well hidden.
Thanks in advance for any hints.
Solved. For what reasons ever:
export PYTHONPATH=${PYTHONPATH}:/usr/lib/python2.7/site-packages/
is required to set the PYTHONPATH. After that step it works like a charm.
So I'm tinkering around with a Myo Armband. And I found out that there are some Python wrappers / bindings for it (https://github.com/smartin015/MYO-python). However, I'm getting an error when I try to run the examples.
dyld: Library not loaded: #rpath/myo.framework/Versions/A/myo
Referenced from: /Users/[usr]/Documents/myo/MYO-python-master_two/./PyMyo
Reason: image not found
I've gone over here to read up on what an #rpath is: https://mikeash.com/pyblog/friday-qa-2009-11-06-linking-and-install-names.html
And I've been looking up other similar questions on StackOverflow. But so far, I'm not really sure where to start solving this.
So, what does "Reason: Image not found", mean? And how should I solve this error?
I'm running OSX 10.10.1, and just using the standard stock python that shipped w/ it 2.7.6, and its running out of /usr/bin/python
Thanks!
Welp. That was an easy fix.
Grab a copy of myo.framework out of the SDK, and paste it into /Library/Frameworks
Didn't think it would be that straightforward. Leaving this answer here for future reference.
