I have 3.9 python and I want to download chatterbot library so I did 'pip install chatterbot' but I'm having this error. how can i fix it?
enter image description here
This error could be caused by several issues, if you don't need the newest version, the easiest thing to do is to install an older version. (Uninstall the previous version before downgrading)
pip install chatterbot==1.0.4
If this isn't possible you could try reinstalling pip using,
python -m pip install --upgrade --force-reinstall pip

I am intalling Rasa X in a Python 3.7 conda environment on Windows 10. pip version is 20.3.3.
pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple
It have been going on for 5-6 hours and seems to be confused:
Any idea what I can do to fix this?
It is caused by the dependency resolution backtracking logic introduced in pip v20.3.
(docs)
A fix for now is to downgrade pip to v20.2, with:
pip install --upgrade pip==20.2
Instead of downgrading pip you can also use the old dependency resolver until pip 21.0 ships (that's when they strip the old resolver from the code base), like so:
pip3 install --use-deprecated=legacy-resolver rasa-x --extra-index-url https://pypi.rasa.com/simple
After facing this issue for quite a while, I finally got if fixed after enquiring at rasa forum.
With rasa==2.7.0 and pip==20.2, I ran the command pip install rasa-x --extra-index-url https://pypi.rasa.com/simple which was quick. It installed rasa-x==0.40.1 for me.
I had the same problem, I downgraded pip to v 20.2. Then I had to download Visual Studio Build Tools 2019 and the issue is resolved.
The latest version of pip 21.3. also solves the problem. Just try and upgrade pip by using
pip install --upgrade pip
I am new to python and trying to install Numpy package in pycharm but I get an error in return please help me solve this problem I have uploaded a picture of this error.
I attempted to install pip within pycharm interpreter still no luck!
Failed to install NumPy Package
This is because of a mismatch between your version of pip and numpy. See answer. Thus, first you must upgrade your pip:
On Linux or macOS:
pip install -U pip
On Windows:
python -m pip install -U pip
Once pip is updated, you may install numpy.
Since I upgraded my pip3 from 9.0.1 to 10.1 to try to solve this problem
(python 3.5 in statsmodels ImportError: cannot import name '_representation'),
I can't manage to install any packages with pip3; it appears this is a problem caused by the latest version of pip3 with debian9.
So I try to solve it by installing the previous version of pip3. But I don't know how to do it. (I'm new on linux and I already block my PC twice).
You can install a specific version of pip using pip:
pip3 install pip==9.0.3
I uninstalled pip by mistake and my question is how I can install it back? I am using windows.
C:>Python-2.7\python.exe -m pip uninstall pip openpyxl
I wanted to uninstall openpyxl but I forgot to delete pip
Installing pip is a simple 2-step operation.
first, you have to get the latest version of pip installer file.
second, You have to run a python get-pip.py on the file you have downloaded.
the file you download in the first step is named get-pip.py and, when ran using python is going to download and install pip on your os.
and you can always read the documentations.
On a windows 7 machine I have pip version 1.5.6 installed:
pip 1.5.6 from C:\Users\dietz\PNC\tas\ENV\lib\site-packages (python 2.7)
In order to find the reason for an error I want to install a different version of pip, which worked fine for me. So how can I uninstall pip and install version 1.2.1 instead?
pip itself is just a normal python package. Thus you can install pip with pip.
Of cource, you don't want to affect the system's pip, install it inside a virtualenv.
pip install pip==1.2.1
If downgrading from pip version 10 because of PyCharm manage.py or other python errors:
python -m pip install pip==9.0.1
If you want to upgrade or downgrade to different version of pip, better use --upgrade option at one go instead doing it in two steps. i.e. first uninstalling the existing and then re-installing to new version, below does both in one go as shown below.
USE: Executed on WIN10 with Bash
python -m pip install --upgrade pip==19.2.3
$ python -m pip install --upgrade pip==19.2.3
Collecting pip==19.2.3
Using cached pip-19.2.3-py2.py3-none-any.whl (1.4 MB)
Installing collected packages: pip
Attempting uninstall: pip
Found existing installation: pip 21.3.1
Uninstalling pip-21.3.1:
Successfully uninstalled pip-21.3.1
Successfully installed pip-19.2.3
well the only thing that will work is
python -m pip install pip==
you can and should run it under IDE terminal (mine was pycharm)
If you have to downgrade pip version do following steps:
step1. pip uninstall pip
step2. pip install pip==version number you want to install or downgrade
step3. check version of pip using pip --version
This process also works when any other package giving error exit code(2) you can follow these steps and install your package.
