pip not installing cryptography - cryptography
I am running pip on an Arduino Yun, which runs OpenWRT, a variant of Linux.
On this device, I already have multiple packages installed, such as crypto, pycrypto, pyOpenSSL, etc.
When I run pip install cryptography:

Could not find a version that satisfies the requirement cryptography (from versions: )

When I run pip show cryptography, it returns a blank.
When I run pip show pip (for comparison):

When I run pip search cryptography:

By contrast, I then tried a different package: pip install crypto:
Requirement already satisfied (use --upgrade to upgrade): crypto in /usr/lib/python2.7/site-packages
Requirement already satisfied (use --upgrade to upgrade): shellescape in /usr/lib/python2.7/site-packages (from crypto)
Requirement already satisfied (use --upgrade to upgrade): Naked in /usr/lib/python2.7/site-packages (from crypto)
Requirement already satisfied (use --upgrade to upgrade): requests in /usr/lib/python2.7/site-packages (from Naked->crypto)
Requirement already satisfied (use --upgrade to upgrade): pyyaml in /usr/lib/python2.7/site-packages (from Naked->crypto)
Any idea what is going on here, and how I can successfully install cryptography?
It seems pretty clear that you have networking issues. This is not normal:
'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x76895850>: Failed to establish a new connection: [Errno -2] Name or service not known'

pip install tensorflow - no matching distribution
I am following TensorFlow's installation guide for Windows 10 & WSL2.
But I get the following when I finally get to the point of installing TensorFlow,

(tf) root#SCED:~# python --version
Python 3.9.16
(tf) root#SCED:~#
I set up the environment with Python 3.9 as recommended in the above link. I have followed all the NVIDIA driver prerequisites.
I had a look to see if pip was installed,
(tf) root#SCED:~# which pip
/root/miniconda3/envs/tf/bin/pip
It is, so what's the issue here?
EDIT :: There have been some suggestions that this is a Python version issue. I repeat, I am following Tensorflow's official documentation. They seem to be under the impression that Python 3.9 is the one to use - they'd know right? The answers linked to in the comments are badly out of date.
once pip installed, try this line? python3 -m pip install --default-timeout=10000 tensorflow-macos
Problems with Nexus hosted pypi repos after updating from 3.46 to 3.47
Hello today I updated my NEXUS OSS repo manager from 3.46 to 3.47.
In the system status page I am seeing the error message:
X transactions with excessive retries in last hour
with the counter X steadily mounting.
Users are unable to download pip packages from the repository.
The error is:
WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'ReadTimeoutError("HTTPSConnectionPool(host='nexus.mercator-ocean.fr', port=443): Read timed out. (read timeout=15)")': /repository/pypi-all/simple/zarr/
If it works, it works for one package and then the error above happens.
Any ideas ?
