How can I understand which libraries are installed by default by python after first installation? there is a default list packages of python 3.10?
How can I separate libraries that I have installed after the first default python installation? How can i manage them using pip visualizing also the installation date?
thank you
Here you can find the list of standard library packages installed: Python Libraries.
Furthermore I suggest you to use virtualenv in order to separate the future packages in different projects.
In order to get installation date and hour
import pkg_resources, os, time
for package in pkg_resources.working_set:
print("%s: %s" % (package, time.ctime(os.path.getctime(package.location))))
Source code: See when packages were installed / updated using pip

I'm trying to load an existing azure workspace in RStudio Azure Compute Instance like it's shown in this link: https://azure.github.io/azureml-sdk-for-r/. But, after installing azuremlsdk package when I'm running this code azuremlsdk::install_azureml(). I'm getting this error :
Attempting uninstall: certifi Found existing installation: certifi2016.9.26ERROR: Cannot uninstall 'certifi'. It is a distutilsinstalled project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.Error: Error installing package(s): 'azureml-sdk==1.10.0', 'numpy', 'pandas'
By referring to this link : https://learn.microsoft.com/en-us/azure/machine-learning/how-to-troubleshoot-environments; I tried to fix this error by running conda remove certifi through terminal of that Compute Instance & Jupyter Notebook of that Compute Instance. But, no luck.
Does anyone have any experience in resolving this issue. Please help.
Azure ML has issues with Python versions and its dependency packages, make sure you are using Python package of 3.5 to 3.8 while installing these.
While installing azureml it will search for all the dependency packages and will install all of them, in this process there will be the version issues, like pandas, numpy.. with different pip versions.
From your stack trace looks like the error is happening when we install the packages like pandas numpy etc along with azureml-train-automl-client package so try to install them before hand by checking its versions which are dependent with you python versions packages.
Check the Azure ML documentation for installation of Azure ML Additional packages.
If you investigate them azureml-train-automl requires somes data science packages including pandas, numpy, and scikit-learn.
Kindly follow below commands for conda environment:
pip install azureml-train-automl
pip install --upgrade azureml-train-automl
pip install show azureml-train-automl
It seems that the Python SDK installation conflicts with itself when using Python 3.6 (the default). I was able to install the SDK for Python 3.7:
azuremlsdk::install_azureml(conda_python_version = '3.7')
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.

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
I'm running python 3.6 via anaconda 3, using Visual Studio Code.
I followed instructions like these (Interactive Brokers API install) and downloaded the package to a local directory of mine say: c:\dev\pyib, so now the code is in c:\dev\pyib\IbPy-master
I open that directory in command line and run
python setup.py install
All runs ok.
But then my program, which is in c:\dev\pyib says Module not found. (In my case ibapi). The linter is also showing red.
There is no other python installed on this pc.
Where did the package install to? and how do I check that? What will I find where the package installed itself to that shows me its there?
Or do I have to use a trial-and-error with the linter and sys.path.append()? (I tried that with the directory where the files are downloaded to - to no avail)
I'm trying to set up the PYTHONPATH using the "env" in launch.json from Visual Studio Code, as shown in this unaccepted answer.
Current sys.path:
'c:\\dev\\pyIb',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\python36.zip',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\DLLs',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-
packages',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Babel-2.5.0-py3.6.egg',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\win32\\lib',
'C:\\Users\\user\\AppData\\Local\\Continuum\\anaconda3\\lib\\site-packages\\Pythonwin'
I deleted the ib directory and re-ran the install. The last line says: Writing C:\Users\user\AppData\Local\Continuum\anaconda3\Lib\site-packages\IbPy2-0.8.0-py3.6.egg-info So is the location of the egg-info the location of my undetected module? The actual folder in the site-packages is called ib.
Or could my problems be because of a difference in Lib vs. lib with the lowercase in the sys.path and the uppercase in the actual directory?
But the real question here is still: HOW DO I KNOW WHERE the package was installed what should I search for?
This answer is specific for anaconda3 Python and packages installed using python setup.py install (which is actually using distutils)
Take a look at anaconda3\Lib\site-packages you should see a directory for the package you installed.
The way to know for sure where your package is, is by doing a pip list then trying to pip uninstall and re-install again using the python setup.py install: Here are the detailed instructions:
When uninstalling, pip will tell you it cannot because it was done via distutils.
You'll get a message like this:
DEPRECATION: Uninstalling a distutils installed project (ibpy2) has been deprecated and will be removed in a future version.
This is due to the fact that uninstalling a distutils project will only partially uninstall the project.
You'll be prompted to continue anyway. If you choose No, then you can find the directory in
C:\Users\<yourusername>\AppData\Local\Continuum\anaconda3\Lib\site-packages
Thanks to Emanuel Mtali for pointing me in the right direction
Some more information:
The problem I had was due to a stupid mistake of mine. I was running setup of a different (but related) package not used anymore. IbPy2 instead of TwsAPI. I was supposed to run the setup.py of the package installed via the latest version of the MSI from IB, and NOT the IbPy2 package. :-(
I'm trying to remove a package I apparently installed sometime ago (can't remember really) and I'm finding it harder than I thought it would be (the package's name is astropy).
If I do:
import pip
inst_packgs = pip.get_installed_distributions()
inst_packgs_lst = ["%s" % (i.key) for i in inst_packgs]
print inst_packgs_lst
the package is listed as installed.
but if I try:
pip list
the package is not listed as installed.
If I do:
pip search astropy
the package is listed as an available package in PyPi.
If I try:
pip uninstall astropy
I get:
Cannot uninstall requirement astropy, not installed
Storing debug log for failure in /home/gabriel/.pip/pip.log
Why is this not working? How should I remove this package from my system?
UPDATE
pyenv is installed in my system and it was set to a different version locally, which is why the package didn't show. Sorry everybody, this question should be closed/deleted.
https://pip.pypa.io/en/latest/reference/pip_search.html
pip search your_query
"searchs for PyPI packages whose name or summary contains your_query".
astropy exists in PyPI but is not installed in your system
Try :
pip list
instead to get a list of installed packages.
Answering my own question for completeness sake.
pyenv was installed in my system and it was set to a different version locally, which is why the package didn't show.
I installed libtorrent-rasterbar on a mac with brew. After I installed I check if it was good installed with the command:
brew install libtorrent-rasterbar
And I get:
Warning: libtorrent-rasterbar-0.16.10 already installed
So installation looks to be ok.
If I go to python and type "import libtorrent" y get an error.
Also if I type:
>>>help('modules')
I dont see libtorrent in the list.
What I'm doing wrong?
Brew has nothing to do with Python. It'll just install system libraries. If you want to install libraries/modules for Python, you should use pip (recommended) or easy_install.
I couldn't find very good Python support for libtorrent in particular, although there is great support for other torrent libraries like PyTorrent.
If you must use libtorrent-rasterbar, there's a great tutorial on how to do it on Super User
