can't launch tensorboard from mac terminal

problem: I can't run "tensorboard --logdir=summaries" in my terminal because I get this error
system: macbook pro running Catalina
environment: running pyenv with python3 as global
package: I have tensorflow 2.2.0 installed via pip
I have setuptools 49.1.0

the setuptools version you have is 40.8.0.
tensorboard needs setuptools>=41.0.0.
So there are two solutions:
update setuptools to >=41.0.0
create a new environment with setuptools>=41.0.0.
MacOs may not allow you to update setuptools, due to system integrity protection
Adding --user python to the command allowed this to work.
In other words
pip install --upgrade setuptools --user python

As it turns out I was not using Pyenv correctly. Once I used "pyenv global system" then I was able to update the pip packages correctly and the right setuptools was installed and TensorBoard ran as expected

Python-pip : Invoice2data package installation error through pip

I am trying to install invoice2data package through pip but i am getting the following error :

I have tried uninstalling pip completely and then reinstalling again still I get the same error. Also tried other StackOverflow solutions but still it didn't help.

i tried the command in python 3.7.2 and it was installed succesfully. This is the command used
"python -m pip install invoice2data"

Unable to create virtual environment

I am unable to create virtual environment using both Python 2.x or Python 3.x. When I try create virtual environment I get error:

The same error occurs for Python 3.x. Can you help me?

I had a similar problem when trying to do this with Python3. Try this command:
sudo python3 -m <your virtual env name>

First, make a directory of any name :
mkdir testing
Then, moved to this newly created directory named testing :
cd testing
When you type following command in this directory:
python3 -m venv env
You got error like :
The virtual environment was not created successfully because ensurepip is not
available. On Debian/Ubuntu systems, you need to install the python3-venv
package using the following command.
apt install python3.8-venv
Type the following command but before that keep an eye on the version of python you installed on the machine; in my case its python3.8
sudo apt install python3.8-venv
Now, we can create a virtual environment and store its tools in the "bhandari" folder .
python3 -m venv bhandari
Note: you can named this "bhandari" folder; anyname you like( Standard practice is to name it "env" ...)
Now to activate your virtual environment, from the directory of your folder, type the following command this will activate our virtual environment in the “bhandari” folder
source bhandari/bin/activate
If you have successfully activated your virtual environment, you should see the (bhandari) word indicating that we are working in a virtual environment.
After this, we can install anything that will be isolated from the rest of the system....

Error after installing EB CLI 3.x

I am trying to install the elastic beanstalk CLI on an EC2 instance (running AMI) using these instructions:
http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/eb-cli3-getting-started.html
I have python 2.7.9 installed, pip and eb. However, when I try to run eb I get the error below. It looks like it is still using python 2.6. How do you fix that?
Thanks!

Pip is probably set up with Python 2.6 instead of python 2.7.
pip --version
You can reinstall pip with Python 2.7, then reinstall 2.6
pip uninstall awsebcli
wget https://bootstrap.pypa.io/get-pip.py
python get-pip.py
pip install awsebcli

I had the same problem, the fix for me was actually to upgrade to latest Beanstalk stack ( eb upgrade ). Note there are downtime etc. So investigate if you can run the latest stack before upgrading.

The "smartest" solution for me was to install python-dev tools
sudo apt install python-dev

Folder is created alright, but files like activate are missing. Anyone? (I have xcode 3.2.3 installed. running python 2.6, osx 10.6.8)

Your developer tools are not installed correctly. I recommend installing Xcode 4.

I had the same error messages trying to run virtualenv on a up-to-date Max OS X Lion (10.7.2) installation with XCode installed and very up-to-date using the App Store.
I missed the /usr/bin/install_name_tool as well, however it is there in the system. Use the terminal in the following code blocks.
$ locate install_name_tool
/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/install_name_tool
/Developer/usr/bin/install_name_tool
/Developer/usr/share/man/man1/install_name_tool.1
I made a simlink from the /Developer/usr/bin to the /usr/bin with
$ sudo ln -s /Developer/usr/bin/install_name_tool /usr/bin/install_name_tool
Entering the 'which' command yields:
$ which install_name_tool
/usr/bin/install_name_tool
After that I did the virtualenv magic
$ virtualenv -p python2.6 myvirtenv
Running virtualenv with interpreter /opt/local/bin/python2.6
New python executable in myvirtenv/bin/python
Installing setuptools............................done.
Installing pip...............done.
Works like a charm now!

Use install_name_tool from #gregglind's fork of virtualenv:
git clone https://github.com/gregglind/virtualenv.git
cd virtualenv
git checkout feature/install_name_tool
sudo python setup.py install

Get the XCode Command line tools from here:
https://developer.apple.com/downloads/index.action?name=for%20Xcode%20-#
I just fresh installed Lion, and installed XCode from the App Store - and these didn't get installed at the same time, need a separate install now I guess...
