[weewx-user] Re: rtgd-0.5.5 extension Wind Direction Average

[gjr80]

Thanks for spotting this. There is an issue is v0.5.5 that maps current 
wind direction to both the 'bearing' and 'avgbearing' fields used by the 
SteelSeries gauges. I should have a fix by tomorrow.

Use the MQTT driver which takes the data directly from your mosquitto 
server.
Avoids all the middleware.
I use Rich's excellent package.

[weewx-user] rtgd-0.5.5 extension Wind Direction Average

[David Marshall]

Built a new station using an esp32 which mqtt’s data every second to a 
Raspi. A python program converts this to a txt file which I then file parse 
into weewx. All ok.
I have successfully installed the steelseries gauges and the rtgd 
extension. All works fine and it is fantastic to see the gauges updating in 
real time.

Just one small problem - the Wind Direction gauge shows latest and average, 
but the average is always the same as the latest. Tried playing with the 
rtgd.py program but even when I set data[avgdirection] to a different 
value, nothing  changes.

Any ideas?

Re: [weewx-user] Re: No module named 'Cheetah'

[Tom Keffer]

For some reason your copy of pip3 is using packages in the Python 2
library. Somehow it got broken. Perhaps it has the wrong shebang at the
top?

Try reinstalling it.

[weewx-user] Re: No module named 'Cheetah'

[Steve]

Thanks Vince.

I will update the OS when I get a chance, the Pi does a few other things 
besides Weewx. But like you mentioned, unless I get it current, I'll be 
battling stuff like this forever. I rolled back to v4.3.0 as I saved the 
image before playing with it.

Now would be a great time to switch to python3 if you can, given that 
python2 is almost two years out of supportespecially since you are 
running a setup.py installation and can easily do a backup of the whole 
/home/weewx tree in one step...just in case.

As Tom suggested, just use 'pip3' and 'python3' to be darn certain you use 
the desired 'supported' python version for your os.

Also, your os is 'really' out of date as well if you see python 3.5 in 
/usr/lib.  A current raspi would have python 3.9 in /usr/lib, so you might 
think about spending the five or so bucks and tossing a new SD card in with 
current RaspiOS and getting everything current now.  Your time is worth 
something to you too, as you might be battling version things for a long

Re: [weewx-user] No module named 'Cheetah'

[Tom Keffer]

I can think of two reasons why this might be happening.

1. You are using a Python 2 version of pip, which will install packages in
the Python 2 directory hierarchy. If you then run weewxd using Python 3, it
won't find it.

I almost never invoke Python as "python", nor pip as "pip". Instead, use
the "3" suffix: python3 or pip3. That way you can be sure of which version
you're getting.

2. Did you try to install Cheetah from the weewx distribution subdirectory?
If so, pip will see the setup.cfg in there and install it in a funny place
where Python can't find it. Take a look in /home/weewx/bin and see if
Cheetah ended up there.

If that's the case, cd to something else and try again.

cd /home/weewx
pip install Cheetah3

[weewx-user] No module named 'Cheetah'

[Steve]

Probably the wrong forum to ask, but I'm at my wits end. I've always used 
the setup.py method to update WeeWx.

I updated WeeWX to 4.9.1 from maybe 4.3.0? Followed the setup.py 
instructions (in /usr there are python3 and python3.5 directories).

I get an error in the log file "No module named 'Cheetah'"

I get this in my terminal 

@rpi3:~# pip install Cheetah3
DEPRECATION: Python 2.7 reached the end of its life on January 1st, 2020. 
Please upgrade your Python as Python 2.7 is no longer maintained. pip 21.0 
will drop support for Python 2.7 in January 2021. More details about Python 
2 support in pip can be found at 
https://pip.pypa.io/en/latest/development/release-process/#python-2-support 
pip 21.0 will remove support for this functionality.
Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: Cheetah3 in 
/usr/local/lib/python2.7/dist-packages (3.2.6.post1)

Re: [weewx-user] Installing and use weewx with a virtual environment

[Tom Keffer]

Unfortunately, as you discovered, this is a little tricky. If you run
setup.py from the virtual environment, things end up in funny places.

Instead, use the system's python to set things up using setup.py, then
switch to the virtual environment to install dependencies, then run weewxd.
But, first you'll need configobj, because setup.py requires it. However, DO
NOT INSTALL configobj from the weewx distribution subdirectory, because pip
will see the setup.cfg and put configobj in a funny spot.

Here's  the way I do it:

# First install configobj. Can be done anywhere, but NOT in the weewx
distribution subdirectory
cd /home/weewx
python3 -m pip install --user configobj
# Unpack the tarball, then cd into the resultant subdirectory
tar xvf weewx-4.9.1.tar.gz
cd weewx-4.9.1
# Set up /home/weewx using the system's version of python
python3 setup.py install
# Now set up the venv in /home/weewx
cd /home/weewx
python3 -m venv weewx_venv
# Activate it
source ./weewx_venv/bin/activate
# Install dependencies in the  virtual environment
python3 -m pip install configobj Cheetah3 Pillow pyserial pyusb pyephem
# Now you can run weewxd in the virtual environment
python3 ./bin/weewxd

For running as a systemd daemon, set up your systemd file so that it uses
the version of Python in the venv. That is, ExecStart will look something
like this:

ExecStart=/home/weewx/weewx_venv/bin/python3 /home/weewx/bin/weewxd
/home/weewx/weewx.conf

A major goal of WeeWX Version 5 is to make this all easier. In particular,
use pipenv, or similar tool, to install things from pypi.org into a virtual
environment. Unfortunately, we may end up with a bit of a hybrid mix
because the Python install tools are not really designed to handle data
such as the skins and configuration file.

Let me know how things go.

[weewx-user] Installing and use weewx with a virtual environment

[gearoid]

I'd like to be able to install weewx and run it using a virtual environment 
instead of using the system's interpreter.

When I run "sudo  setup.py install" I get an error 
about not being able to use both prefix and exec_prefix.
I commented out exec_prefix= in setup.py.
The install runs but a bunch of files are placed in the virtual 
environment's directory and not in /home/weewx.

I moved those files into /home/weewx myself and it seem to be working.

I'd like to be able to do that without those hacks.  If someone can give 
some pointers and it's a reasonable thing to be able to do I'd be happy to 
make the PR.

I'm using Ubuntu, pyenv to install python 3.10.8.
Using python venv to create the 3.10.8 virtual environment and then pip to 
install the required modules (so no apt installed packages).

Gearoid.
