I want to use this code:
from dipy.viz import has_fury
from fury import window, actor
so at first I installed the DIPY and Fury. but when I run pip install Fury it didn't work and this error was showing:
ERROR: Cannot uninstall 'vtk'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
I tried to uninstalled vtk but I couldn't and same error showed to me.
This error means that this package's metadata doesn't include a list of files that belong to it. Most probably, you have installed this package via your OS' package manager, so you need to use that rather than pip to remove it.
You can either reinstall the package for python while ignoring the installed version with
pip install --ignore-installed vtk
pip install --ignore-installed fury
or if you don't wanna do that you can use a virtual environment and install the libraries in the virtual environment.

I use Python and pycharm as a tool.
If you use the pip statement to install the library, you will get an error.
For example, if I want to download the torch (1.6.0) version and type pip install torch==1.6.0,
It says no version.
This is not the end, but some libraries continue to cause strange conflicts and will not be installed.
For example, if you type pip install poro to install the poro library, an unknown error pops up and the installation fails.
I'm not asking for a pororo installation.
My question is, I want to know how to download the library without relying on pycharm.
I want to download it separately from a site like pypi and put the library directly into the virtual environment (conda).
What should I do?
The following worked for me:
First, install mkl using conda:
conda install -c anaconda mkl
Then run this:
conda install -c pytorch pytorch
I'm trying to install a python package directly from github. In my case that's SciANN. When I selected my environment in conda using conda activate myenv and afterwards install this package as explained in this post using the following lines of code:
conda install git pip
pip install git+git://github.com/sciann/sciann.git
it is successfully installed and I get the message "Successfully built SciANN" in the end of the insatllation procedure. When I then open spyder and type import sciann I get the error ModuleNotFoundError: No module named 'sciann'. I also tried to use pip3 instead of pip but this did not change something.
Have I missed something? Is this package now installed correctly into my environment myenv?
The deleted answer from Jay Prakash together with the comments brought me on track. Yes there can be different versions of packages installed. So in my case SciANN was installed using pip as they currently do not offer a conda installation while all my other packages where installed with conda. I ended up having two different versions of tensorflow installed, one from pip and one from conda so I deleted one. Additionally I used Python version 3.7 while this package supports only up to 3.6. And I had to use a non official tensorflow version because my CPU does not support AVX which is a whole new topic.
I am new to Python and Conda. I am trying to install a package called DavGIS. I downloaded this package and I downloaded Anaconda. Then I opened Anaconda Prompt and tried to install the package with the command conda install davgis. This gave an error message regarding not begin available on current channels.
Then I tried pip install davgis, but this gives an error as well. In the picture the commands and errors are showed. I am using Windows 10 64-bit and Anaconda with Python 3.6
Errors installing package:
You cannot install this package, because there is no package. A python package contains a file called "setup.py". And to install it with pip (or conda) it need to be referenced on their server.
If you want to use it in your project, you can copy it directly in your source folder (where your code is).
If you wanna do it without copying, you can follow this method: How to install Python module without setup.py?
I am managing several modules on an HPC, and want to install some requirements for a tool using pip.
I won't use virtualenv because they don't work well with our module system. I want to install module-local versions of packages and will set PYTHONPATH correctly when the module is loaded, and this has worked just fine when the packages I am installing are not also installed in the default python environment.
What I do not want to do is uninstall the default python's versions of packages while I am installing module-local versions.
For example, one package requires numpy==1.6, and the default version installed with the python I am using is 1.8.0. When I
pip install --install-option="--prefix=$RE_PYTHON" numpy==1.6
where RE_PYTHON points to the top of the module-local site-packages directory, numpy==1.6 installs fine, then pip goes ahead and starts uninstalling 1.8.0 from the tree of the python I am using (why it wants to uninstall a newer version is beyond me but I want to avoid this even when I am doing a local install of e.g. numpy==1.10.1).
How can I prevent pip from doing that? It is really annoying and I have not been able to find a solution that doesn't involve virtualenv.
You have to explicitly tell pip to ignore the current installed package by specifying the -I option (or --ignore-installed). So you should use:
PYTHONUSERBASE=$RE_PYTHON pip install -I --user numpy==1.6
This is mentioned in this answer by Ian Bicking.
I am on a Windows machine and I want to install a Python module from GitHub using pip directly from IPython.
The simplest command that seems it should work is:
!pip install https://github.com/japerk/nltk-trainer.git
I have also tried:
!pip install https://github.com/japerk/nltk-trainer.git#egg=nltk-trainer
I've used variants including -vvv, etc.
However, I'm getting the following error. Why?
Cannot determine archive format of C:\Users\timo\AppData\Local\Temp\pip-build-183bwemw\nltk-trainer
go to the https://github.com/japerk/nltk-trainer and download the project zip file. extract the zip file and put it somewhere in your computer.
open command prompt in windows and go inside the folder that you extracted earlier(you must be in the folder that has setup.py file in it).
enter the following command: python setup.py install
python tries to install nltk-trainer . during installation some other dependency might be installed too. you need numpy and scipy to be installed. if any problem happened during installation of numpy or scipy try installing them manually first by using pip install numpy and pip install scipy
if you can't install numpy and scipy using pip command use the following link:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
this site has compiled version of these libraries ( and other libraries if you need to install them too) you can download .whl file that is based on your python version and os architecture and install them using pip install filename.whl command ( you need to be in the folder that your whl file is) for example for python3.4 and 64bit operating system you may download scipy‑0.16.0‑cp34‑none‑win_amd64.whl file.
