I tried below command but it doesn't worked.!!
virtualenv --system-site-packages ~/tensorflow
-bash: virtualenv: command not found
The error virtualenv: command not found tells you exactly what is wrong. You need to install virtualenv to use it. Once you install it the command above should work. Then you will need to activate your virtual environment and use pip to install tensorflow.

I'm trying to set up a virtual environment. I have a Mac, using Mac OS Big Sur 11.1. I have installed the latest stable version of python, but when I enter this command into the terminal window
-m pip install pipenv pip --upgrade
I get the following error
zsh: command not found: -m
before, it would say
"No module named pip"
Do I have to install pip separately with
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
I thought pip was included by default when you install python? I think I might have pip because when I type
python3 -m pip
into the command line, I get a long list of commands (install packages, download packages, etc.) General options... Thus should I install pip? one person on reddit said,
Pip is not necessarily included with any version of Python. In many
distributions, it must be installed separately.
If python3 -m pip works, then you have a bad install, not a missing
one.
thus did I incorrectly install python? When I was installing it there was no option to
"add python to PATH"
Do I have to do this on a mac? If I input
python3 -V
in terminal, I get
Python 3.9.2
Thanks
i solved this by running,
pip3 install pip --upgrade
I couldn't activate TensorFlow env on Ubuntu(16.04 LTS) bash
I have tried "activate tensorflow" and source "activate tensorflow", but it did not work
"activate tensorflow" and
"source activate tensorflow" not working
I expect this : (tensorflow)$
but I'am getting this:
"activate tensorflow" display: /home/user/anaconda3/bin/activate: 5: /home/user/anaconda3/envs/tensorflow/etc/conda/activate.d/activate-binutils_linux-64.sh: Syntax error: "(" unexpected
while "source activate tensorflow" displays nothing, though my TensorFlow environment is active.
Could you try creating a virtual environment using command in terminal virtualenv myenv. If virtualenv is not installed then install it using pip install virtualenv and run the above mentioned command again.
After creating it, open it using source myenv/bin/activate. Now you must be in the environment. If you see (myenv) on the left side in terminal then yes you are.
Now install TF using pip install tensorflow and you are good to go.
How about these three steps?
$ sudo apt-get install python-pip python-dev python-virtualenv
$ virtualenv --system-site-packages ~/tensorflow
$ source ~/tensorflow/bin/activate
There are already two posts on stack overflow on this topic; however, none of them have resolved or addressed my specific situation.
I have installed pytest via pip install pytest. I am able to import the library in Python as well.
The problem is that when I try to use the py.test command in Terminal, I get py.test: command not found.
Does anyone have any insight as to why I am not able to use the command in the terminal?
EDIT: It even shows up as an installed package:
$ pip list
cycler (0.9.0)
matplotlib (1.5.1)
numpy (1.10.1)
pip (8.1.0)
py (1.4.31)
pyparsing (2.0.7)
pytest (2.9.0)
python-dateutil (2.4.2)
pytz (2015.7)
scipy (0.17.0)
setuptools (7.0)
six (1.10.0)
tensorflow (0.5.0)
vboxapi (1.0)
wheel (0.26.0)
using python -m pytest will work for you.
Or if you using virtual environment and installed pytest on virtualenv you should then run py.test alongside your virtual environment.

I already had the latest version of pytest on macOS with Homebrew-installed Python 2.7 and this fixed it:
pip uninstall pytest
pip install pytest
Are you on a mac with homebrew by any chance?
I had the same issue and it basically came down to permissions/conflict with the mac os base installed python. pip install would not install or link stuff into /usr/local/bin (it happened with both virtualenv and pytest).
I uninstalled python 2.7 completely with homebrew (brew uninstall python).
Next, I reinstalled python with homebrew to fix pip (it was not a symlink in /usr/local/bin/pip where it should have been linked to Cellar) -- brew install python
Then I uninstalled pip with sudo -- sudo python -m pip uninstall pip to remove the pip owned by root
Now I uninstalled and reinstalled python with homebrew again to reinstall pip with the correct permissions brew uninstall python && brew install python
Next I fixed the python symlinks brew link python
Finally, pip install pytest worked! (and so did pip install virtualenv)
I found the information in the chosen answer from this post very helpful:
https://superuser.com/questions/915810/pip-not-working-on-hombrew-python-2-7-install.
If you're not on a mac, sorry for the noise...
I may be late, but while exploring this I noticed that this can be because the Scripts folder for python is not present in the PATH.
For me this is my scripts folder:
C:\Python38\Scripts\
If the path is a problem then running pip install pytest should actually you give you the warning with the path it was added to.
This should be present in the path. If on windows, edit the environment variables and this location to the PATH.
For me the path was incorrect because of an improper installation of python
I had the same issue. I had pytest v2.8.3 installed and the binary was on my path but under the name py.test. Upgrading to v3.0.3 added the regular pytest executable to the path.
I had the same problem. I have changed the Python installed folder permission to full access. And then uninstalled the pytest and installed again.
pip uninstall pytest
In my case, I had a similar issue in ubuntu 20.04. The below solution worked for me.
Cause: Shell remembers the previous version or previously used Path, hence we need to force the shell to 'forget' the old location - with -r
hash -r pytest
Then execute the tests it should work fine.
For MAC users:
Download python universal installer for mac:
https://www.python.org/ftp/python/3.10.5/python-3.10.5-macos11.pkg
Then try to install pytest module in terminal using this command:
pip install pytest
Hope this will fix the issue. Thanks!
use the command, pip install -U pytest and install it in your cmd prompt, it will solve the issueenter image description here
I used macbook air m2, and the way I deal with this problem is:
Command in terminal in macbook:
which pytest
/opt/anaconda3/bin/pytest -> my terminal shows this
Then you got the path of pytest, in the "Command", before "pytest", add its path and following with the path of python file you wanna test.
/opt/anaconda3/bin/pytest /Users/cindyng/Desktop/Testing.py
Done, and if you cannot find the path of python in macbook, "which python" also helps, and you can put it in "Home" and "Custom Python Builder".
Hope that helps, good luck!
I Fixed this issue via below steps.
1.First uninstall existing pytest.
2.Check python version.
3.then verify pytest version is supported with python version or not via github issue tracker.
4. via sudo install pytest
sudo pip install pytest
5. verify pytest version and insatlled correctly or not.
pip list
pytest --version
6.run any test using pytest test_abc.py
I encounter the same problem, python -m pytest works for me.
I have installed virtualenv 1.9 which includes pip, but cannot install nltk on my Mac. First it does not recognize pip as a command. Second how do I install nltk?
You should be able to run the following command to setup the virtual environment:
$ virtualenv venv
New python executable in venv/bin/python
Installing setuptools.............done.
Installing pip...............done.
Then activate the virtual environment using:
$ source venv/bin/activate
Then install nltk:
(venv)$ pip install nltk
When you are done with the virtual environment run:
$ deactivate
You may want to try installing Python using Homebrew rather than using the Python version included with the OS. With 'brew' you will not need to use virtualenv (unless you want to) because brew installs packages to /usr/local owned by you. So you can simply run 'pip install '.
Follow the installation instructions here for Homebrew. Then run:
$ brew install python
$ pip install nltk
You can install virtualenv as well if you want it.
$ pip install virtualenv
Using Python 2.7 installed via homebrew. I then used pip to install IPython. So, IPython seems to be installed under:
/usr/local/lib/python2.7/site-packages/
I think this is true because there is a IPython directory and ipython egg.
However, when I type ipython in the terminal I get:
-bash: ipython: command not found
I do not understand why this ONLY happens with IPython and not with python? Also, how do I fix this? What path should I add in .bashrc? And how should I add?
Currently, my .bashrc reads:
PATH=$PATH:/usr/local/bin/
Thanks!
I had this issue too, the following worked for me and seems like a clean simple solution:
pip uninstall ipython
pip install ipython
I'm running mavericks and latest pip
Check IPython whether is installed by below command:
$python -m IPython
If you got this result as above picture.
Then run this command on terminal and add into ~/.bash_profile file
$alias ipython='python -m IPython'
So try run "ipython" again on terminal. It works fine for me.
Reference topics:
ipython on MacOS 10.10 - command not found
iPython installed but not found
Create .pydistutils.cfg in your homedir with following content:
[global]
verbose=1
[install]
install-scripts=$HOME/bin
[easy_install]
install-scripts=$HOME/bin
And then: pip install -U --user ipython. Of course $HOME/bin must be in your $PATH. Packages are going to be installed in $HOME/Library/Python, so user only, not system wide.
Try run brew install ipython:
then run xcode-select --install；
run brew install git,
If you got this result as above picture. Refer to enter link description here
At last, run brew install ipython
I use pip3 install ipython is OK.
maybe ipython rely on python3
After trying to a number of solutions like above with out joy, when I restarted my terminal, Ipython command launched. Don't forgot to restart your terminal after all the fiddling!
P.S. I think the brew install Ipython did it ... but can't be sure.
For me the only thing that helped was:
python -m pip install --upgrade pip
Upgrading pip did the work and all the installations started working properly!
Give it a try.
