I'm running a python script which uses Shrinkage class from pyRiemann package.
Even though that I've installed this package, I got this error:
from pyriemann.estimation import Shrinkage
ImportError: cannot import name Shrinkage
I'm using:
pyriemann==0.2.4
Python 2.7.13 :: Anaconda custom (64-bit)
any idea what this problem is?
It seems that Shrinkage is not in pyRiemann 0.2.4.
The code is on Github, so the development version could be installed with:
pip uninstall -y pyriemann
pip install git+https://github.com/alexandrebarachant/pyRiemann
If you work with other people and put the git link in a requirements.txt file, consider locking yourself to a specific commit, e.g. the current latest one. And then remember to change it to pyriemann==0.2.5 once that is released.

I need to use the sksparse.chomod package however my pycharm does not let me install it as it can't seem to find it.
I found the sksparse package on github and downloaded it but I do not know how to add a package downloaded from the internet into a conda environment. So, my first question would be can you download a package from github and add it to your conda environment, and how do you do this?
As I did not know how to do the above I instead saved the package within my project and thought I could simply import sksparse.cholmod. However, the line in my code that says import sksparse.cholmod as sks has no errors with it, so I assumed that meant this was ok, but when I try to run my file I get this error:
import sksparse.cholmod as sks
ModuleNotFoundError: No module named 'sksparse.cholmod'
If I have downloaded the package into my project why can't it be found, yet there are no errors when importing?
The cholmod file is a pyx file which I've been told should not be a problem.
Please could anyone help, I am reasonably new to python and I am looking for a straight forward solution that won't be time consuming.
It was an issue with windows, I was able to fix this using the instructions on this link

We must follow these steps precisely:
(This was tested with a Anaconda 3 installation and Python 3.7)
Install these requirements in order:
'''
conda install -c conda-forge numpy - tested with v1.19.1
conda install -c anaconda scipy - tested with v1.5.0
conda install -c conda-forge cython - tested with v0.29.21
conda install -c conda-forge suitesparse - tested with v5.4.0
'''
Download Microsoft Build Tools for C++ from https://visualstudio.microsoft.com/de/visual-cpp-build-tools/ (tested with 2019, should work with 2015 or newer)
Install Visual Studio Build Tools
Choose Workloads
Check "C++ Buildtools"
Keep standard settings
Run ''' pip install git+https://github.com/EmJay276/scikit-sparse '''
Test ''' from sksparse.cholmod import cholesky '''
Use all the versions stated for numpy etc, however with scipy I installed the latest version and it worked fine.
I'm having trouble installing packages and using them in Pycharm. I've followed various threads (I'm new to Macs and seem to have tried everything) now I'm stuck.
In this case, I want to use the package xgboost.
I have brew installed, after launching a terminal using Rosetta:
%brew install xgboost
Warning: xgboost 1.3.3 is already installed and up-to-date.
It appears installed OK here:
/opt/homebrew/Cellar/xgboost
I also have Python installed here:
/opt/homebrew/Cellar/python#3.9
But no matter how I configure an Interpreter in Pycharm, I can't seem to get the package recognised.
Where have I gone wrong?
I am very unsure exactly how, but I've got this working.
Following: https://abbasegbeyemi.me/blog/homebrew-python-apple-m1
I changed the order of elements in my path:
export PATH=/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/homebrew/bin
then a new interpreter in Pycharm using:
usr/local/Cellar/Python#3.9/3.9.2_2/bin/python3.9
Now I can install packages just using pip in pycharm and it works.
This has been 6 hours of pain - warning to anyone who isn't well versed in macs, setting up an M1 for python dev was a complete nightmare for me.
Docs: https://xgboost.readthedocs.io/en/latest/build.html
Pre-built binary wheel for Python
If you are planning to use Python, consider installing XGBoost from a pre-built binary wheel, available from Python Package Index (PyPI). You may download and install it by running
# Ensure that you are downloading one of the following:
# * xgboost-{version}-py2.py3-none-manylinux1_x86_64.whl
# * xgboost-{version}-py2.py3-none-win_amd64.whl
pip3 install xgboost
Conda gives error when I run any command with it.

from ruamel.yaml.comments import CommentedSeq, CommentedMap # pragma: no cover
ImportError: No module named ruamel.yaml.comments
The module ruamel.yaml.comments will normally be loaded from site-packages/ruamel/yaml/comments.py, and not from site-packages/ruamel_yaml/comments.py
Conda seems to have problems with properly supporting namespaces (ruamel.) which I can only attribute to not (yet) being fully pip compatible. That although "namespaces are a honking good idea", and package namespaces have been around for many years.
Assuming you can extend "conda" installations with pip you could try to do a normal install of ruamel.yaml with:
pip install ruamel_yaml==0.11.14
I would not normally recommend such an old version, but that is more likely to work in combination with the version conda uses itself internally.
The alternative would be to switch to using python and pip without conda, that way you can just use the latest version of software from PyPI.
Try pip install ruamel.yaml
It works for me.
Try conda install ruamel.yaml ... pip didnt work for me
Try sudo pip install ruamel_yaml
I went into this file:
/anaconda2/lib/python2.7/site-packages/dateparser/utils/__init__.py
edited this line:
import ruamel.yaml as yaml
to read
import ruamel_yaml as yaml
Changing the dot to an underscore worked for me.... I hope it works for you.
this worked for me:
pip install --upgrade ruamel.yaml --ignore-installed ruamel.yaml
from an answer in matsci.org
https://matsci.org/t/modulenotfounderror-no-module-named-ruamel/36183
The above answer didn't work for me. I had to do a fresh install of the core conda components as described in the conda docs here. Copy and pasted below:
Issue: My conda is broken and I want to fix it without blowing away the current installation
I am getting a conda error and want to reinstall Miniconda to fix it but when I try, it gives me the error that Miniconda (or Anaconda) is already installed and will not let me continue. I want to force the installation.
Resolution: Install Miniconda using the -f (force) option
Download and install the appropriate Miniconda for your computer operating system from the Miniconda download page using the force or -f option as shown:
bash Miniconda3-latest-MacOSX-x86_64.sh -f
NOTE: Substitute the appropriate filename and version for your
operating system.
NOTE: Be sure that you install to same install location as your
existing install so it overwrites the core conda files and does not
install a duplicate in a new folder.
Go to anaconda3\lib\site-packages\rpcq_base.py
and change line #22 :
from ruamel import yaml
to
from ruamel_yaml as yaml
This might not be a popular answer, but it finally helped me after many hours of troubleshooting:
Uninstall conda (I used this stack overflow solution) and also rm -rf miniconda3 in my home directory, fwiw.
Reinstalled conda using data camp's tutorial.
No other solutions worked for me after lots of head banging.
For python3 use
pip3 install ruamel_yaml
if pip3 not installed try at first
sudo apt install python3-pip
For me this was a conda/pip error. I'd tried to install (cwltool in my case) through pip.
It completed successfully, but then running any command gave me the error like above.
ImportError: No module named ruamel.yaml.
It turned out that the pip binary wasn't part of my conda env and was installing cwltool into a completely separate location.
To resolve the issue I completed the following:
conda activate <env I want to install cwltool into>
conda install -y pip
# Run 'rehash' now if you're using zsh to ensure you're using the right pip
pip install cwltool
cwltool -h
To add to what #user612161 has said, go to the directory of parent module (dateparser in this case) requiring ruamel.yaml:
cd anaconda2/lib/python2.7/site-packages/dateparser
and change all occurrences of ruamel.yaml into ruamel_yaml by the following command (Linux):
find . -name '*.py' | xargs sed -i 's/ruamel.yaml/ruamel_yaml/g'
The quick and easy is to ignore the previously installed version in an upgrade
pip install --ignore-installed ruamel_yaml==0.17.4
I was trying to link Bloomberg to Python
pip install --index-url=https://bcms.bloomberg.com/pip/simple blpapi
pip install xbbg
so far, so good.... then I tried to import a module from the package xbbg:
from xbbg import blp
and I was faced with an error, it couldn't find "ruamel.yaml" within the "param.py" within the xbbg module
When I dug into the folder C:/Anaconda3/Lib/site-packages I could see that there was a folder there called ruamel_yaml so I went back to the param.py file and edited ruamel.yaml to be ruamel_yaml as suggested in other posts.
"from xbbg import blp" now worked and I'm able to take data directly from Bloomberg into Python now. Problem solved.
I have a feeling that this issue is being caused by downloading different versions at different times as I've found the learning curve to get setup on Python difficult with many false starts. I was tearing my hair out a bit because I just got Python up and running linked to Bloomberg on my work pc but when I tried to link Bloomberg up to Python on my laptop it kept getting stuck with the "ruamel" issue. The version of Python on my laptop is much older than the version on my work pc. What makes me think that its a version issue is that I did not have to edit ruamel.yaml to be ruamel_yaml in order for me to link Python and BB.
These are just ideas, I'm too inexperienced at this stage to offer much more than to share what happened.
I am working with Scrapy framework to scrap out data from website, but getting the following error in command prompt:
ImportError: cannot import name '_win32stdio'
Traceback is attached as a screenshot.
Kindly revert if require directory structure of my program's directory.
Scrapy can work with Python 3 on windows if you make some minor adjustments:
Copy the _win32stdio and _pollingfile to the appropriate directory under site-packages. Namely, twisted-dir\internet. Download these from https://github.com/twisted/twisted/tree/trunk/twisted/internet
pip install pypiwin32
Granted, this is based on my personal experience. Because the repository will certainly change in the future, readers should beware the age of this answer.
Update: the twisted-win package is no longer required because the appropriate files are now included in the twisted package.
I have gone through the same. I have resolved by updating the twisted package
pip install --upgrade twisted
or
pip uninstall twisted and pip install twisted
get whl of twisted (from below link) according to your os and py version and you are good to go!

I'm new to Python and I'm trying to install web2py in a virtualenv. I'm running a 32 bit python 2.7.3 installation on a 64 bit Windows 7.
From what I read, this should be the process:
install virtualenv (done)
create the virtualenv (done)
install pywin32 in that env (I've read it needs to be installed before the web2py installation)
install web2py in that env
First and foremost: is that right? If so, then...
I tried installing pywin32 through
'''easy_install pywin32-218.win32-py2.7.exe'''
It went fine. Then, I checked the virtual environment's site-packages for a pywin32 folder and it was there, but I couldn't import it into python ('''ther's no module pywin32'''). The environment was definitely active (I double-checked).
As a test, without using virtualenv, I double-click-installed the pywin32 binary (downloaded the 32 bit version for python 2.7 -- pywin32-218.win32-py2.7.exe) but got an error at the end:
'''close failed in file object destructor:
sys.excepthook is missing
lost sys.stderr'''
I downloaded the file again (could be corrupted), tried installing it again but got the same result.
Could anybody guide me or point me to a step-by-step install of pywin32 (if necessary) and then web2py for windows 7? I'd really appreciate it.
its a bug: http://sourceforge.net/tracker/?func=detail&aid=3402824&group_id=78018&atid=551954,
workaround here : http://pywin32.hg.sourceforge.net/hgweb/pywin32/pywin32/rev/a64d8ac23e61
similar to this: Error installing and running pywin32 2.7
In my experience, the command easy_install pywin32-218.win32-py2.7.exe under an active virtualenv works fine.
To test the installation of pywin32, from python you can try:
from win32api import GetVersionEx
print GetVersionEx()
Obtaining something similar to (windows major version, minor version, build number, platform id, additional informations):
(6, 1, 7601, 2, 'Service Pack 1')
You cannot import module pywin32 because it doesn't exist.
After the installation of pywin32, you can install web2py under the active virtualenv (I tested it until to opening the admin interface, no guarantee after this :-):
download the source code from http://www.web2py.com/init/default/download
unzip it to ...\virtualenvdir\Lib\site-packages\ (obtaining: ...\virtualenvdir\Lib\site-packages\web2py\...)
cd to ...\virtualenvdir\Lib\site-packages\web2py
start the web2py server: python web2py.py
At the date, I couldn't install web2py using pip. First of all, it grabs an old version of web2py from PyPy. When I tryed to use this version of web2py I got an error ImportError: No module named .... The same using pip on a copy of the web2py source file.
