I'm having some difficulties importing the module dht11 from the Adafruit library(https://github.com/adafruit/Adafruit_Python_DHT).
I'm using a raspberry pi3 model b, and have installed python 3.5. I downloaded the Adafruit and installed using
sudo python3 setup.py install
and I'm fairly certain that the installation went well since I connected my temp and humidity sensor and using
sudo python3 examples/AdafruitDHT.py 11 2
I get correct reading about temp and humidity, yet when I try to import the dht11 module (I'm using spyder as ide) I get the
'no module named dht11'.
I tried appending the directory in the sys.path but still get the same error.
Edit:
I tried both python 2 and 3, get the same error
Edit2:
I tried other IDE as well, but no one is working.
I opted to launch the script.py directly from terminal since this way it's working. If anyone has a solution, it would be greatly appreciated.

I'm trying to connect my python scripts to an MySQL or MariaDB Server on my RaspberryPi4.
My python script right now just contains import mysql.connector. But when I try to start it via sudo python3 startdb.py I just get import mysql.connector ModuleNotFoundError: No module named 'mysql' as an error.
I get an other error, when I start the script via sudo python startdb.py: import mysql.connector ImportError: No module named mysql.connector.
I searched for a solution on many sites or forums. I mostly just found various versions of pip install mysql-connector-python (also with pip3, mysql-connector-python-rf or mysql-connector) to run but none of them worked for me. The only difference I recognized is that I previously got the error ModuleNotFoundError with both sudo python and sudo python3, but now I only get it with sudo python3.
Does anyone know how to solve this?
Could the fact that my script isn't in a sub-directory of /home/pi/, but instead of /home/, be the problem?
Edit: I just tried executing the script via the desktop mode using my mouse and just clicking on run and it worked. But when I'm using the command line in desktop mode or with a SSH session it doesn't work.
Another Edit: It looks like when I'm starting the script without sudo it'll work just fine. Don't actually know why's that, but I'm good for now. But would be very interesting to know and understand why the sudo makes it "crash".
Thanks and happy to hear some solutions :D
Cooki
raspbian give user mode in running, just in Desktop gives some permission to user for run app as root to access all necessary attributes , use sudo with all initial steps when you download and install project package's
Im working through the w3Schools example of connecting to a mysql database using python.
I'm running raspbian on a raspberry pi.
I've installed the mysql-connector-python library (done using sudo as well and both say it's already installed).
Then I go into the python REPL and try importing to test it but get an error saying it's missing.
Could someone point me to where I'm going wrong here?
I'm have an issue within a python 2.7 (pypy) script which has the code below
from urwid import ExitMainLoop
It's showing me the error in the title of this question even though it's been installed via pip and can be seen in the output when running pip freeze
urwid==1.3.1
This is running on a Raspberry PI 3 in Raspbian and the same set of scripts are running without issue on a Debian VM.
Any help very much appreciated?
After hours of research I have broken down to posting. I am trying to use the Pexpect module with python 3, which I am led to believe is possible from the document page which does say it will run with python 3.2.
Things I have tried: I have tried many different ways of installing including downloading the source and running the command sudo python3 setup.py install. I have also tried installing it with pip and *easy_install* which is what the documentation suggest. It seems that everything goes off with out a hitch until I attempt to import the module in the pyshell. When I type import pexpect I get the error:
class spawn(object):
File "/usr/local/lib/python3.2/dist-packages/pexpect/init.py", line 286, in spawn
write_to_stdout = sys.stdout.buffer.write
AttributeError: 'PseudoFile' object has no attribute 'buffer'
I have also tried googleing the error with no luck. And I have tried using python 2.7 and it works fine. I have tried on multiple debian based operating systems: Ubuntu 12.04 and Kali with the same results.
I feel like there is something obvious I am missing, but I just don't see it. Any points in the right direction Or helping me understand the error message would be much appreciated!
There was a bug in Pexpect 3.0 which stopped it working if sys.stdout was replaced before it was imported. It looks like IDLE replaces stdout, so as you've found, it doesn't work in IDLE & Python 3.
The bug has now been fixed. I'll try to get a new version of Pexpect out in the next few days, and then you'll be able to use it from IDLE.
Having some problems with Gdal installation with python 2.7 on Windows 7 32bit. I am running MSVC 2010. I have followed the instruction from the blog website
http://cartometric.com/blog/2011/10/17/install-gdal-on-windows/
The installation is fine. At the end of it, I am able to run ogr2ogr in the MS-DOS and have gotten the similar screen as listed in the blog.
However, when I am trying to use the command "import osgeo" on the Python IDLE GUI shell. A series of error message is released, reading like the following
"DLL error:.........."
I believe that this might mean that the python binding is of wrong version. I have cleared up my installation by removing the following: Python-Gdal binding, Gdal, Python 2.7
After removing them, I have retried my installation with Python 3.2.3 instead and loaded the Gdal package and python binding accordingly. However, the same error returns.
Is there any intermediate steps that I could take to verify the installation. Any other advice I could have to have the bindings installed? Or is my reinstallation method correct?
I have tried to install FWTools too. It doesnt seem to work either. I have run the Python shell from EV-shell and type in "import osgeo". Have gotten the message "no module exist...."
Thanks
Get the precompiled gdal from here:
