I want to run a .sagews file in python3
I have installed the sage-0.0.0 package on Ubuntu 18.04
pip3 install sage
...
...
Successfully built sage
Installing collected packages: sage
Successfully installed sage-0.0.0
according to the source
I wrote the code on the point.py file:
from sage.all import *
p = 115792089237316195423570985008687907853269984665640564039457584007908834671663
F = GF(p)
E = EllipticCurve(F, [0,7])
E.count_points(2)
I run in the terminal:
sage -python3 point.py
and I get a warning
/bin/bash: sage: command not found
I run in the terminal:
python3 point.py
and
Traceback (most recent call last):
File "point.py", line 1, in <module>
from sage.all import *
ModuleNotFoundError: No module named 'sage.all'
What exactly am I doing wrong? How can you run the sage file using python3?

I'm trying to build pyslam project, and the install.sh file was provided. But when I executed install.sh, the main.py didn't work.
https://github.com/luigifreda/pyslam#install-pyslam-under-ubuntu-2004
Full Installation
In order to run main_slam.py with venv, get in the root of this repository and run the following command:
$ . install_all_venv.sh
N.B.: do not forget the dot! (without '/' !)
This will compile the required thirdparty packages and will also activate the created pyslam environment. Now, from the same terminal, you can run:
$ python3 -O main_slam.py
The result was
(pyslam) (base) ict-526#ict526-MS-7D32:~/pyslam$ python3 -O main_slam.py
Traceback (most recent call last):
File "/home/ict-526/pyslam/main_slam.py", line 27, in <module>
from config import Config
File "/home/ict-526/pyslam/config.py", line 27, in <module>
import yaml
ModuleNotFoundError: No module named 'yaml'
I think the packages didn't install in the venv (pyslam). How can I fix this situation?
My environment is ubuntu20.04, and python 3.9.7.
According to the installaion instruction, python 3.6.9 was required. After install_all_venv.sh, the pyslam venv support python 3.9.7...
After installing cassandra driver by running the command:
sudo pip3 install cassandra-driver, I am getting the error ModuleNotFoundError: No module named 'cassandra' when I try to import the module by running the line cassandra.
I then tried to see what all modules are installed in pip3 by running the command pip3 freeze:
astroid==2.1.0
cassandra-driver==3.16.0
isort==4.3.4
lazy-object-proxy==1.3.1
mccabe==0.6.1
pylint==2.2.2
six==1.12.0
wrapt==1.10.11
Seeing no cassandra, I tried to import the visible module: cassandra-driver and then I ended up with the error:
File "<stdin>", line 1
import cassandra-driver
^
SyntaxError: invalid syntax
Also, when I do correct the hyphen issue with this:
__import__("cassandra-driver"), I get the error:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'cassandra-driver'
My which python3 is: /usr/local/bin/python3 and my which pip3 is: /usr/local/bin/pip3
My OS is MacOS
How to install cassandra?
Note: I am following this documentation.
Did you try to run these demos (from those docs)?
"If successful, you should be able to build and install the extension (just using setup.py build or setup.py install) and then use the libev event loop by doing the following:"
>>> from cassandra.io.libevreactor import LibevConnection
>>> from cassandra.cluster import Cluster
>>> cluster = Cluster()
>>> cluster.connection_class = LibevConnection
>>> session = cluster.connect()
There is a probability that actual module is named differently, e.g. there is another external package called Pillow, but you import it with name "PIL".
In docs they are importing from cassandra.cluster
Docs I'm referring to
$ echo 'import cassandra.cluster' > cassandra.py && python3 cassandra.py
Traceback (most recent call last):
File "./cassandra.py", line 3, in <module>
import cassandra
File "/home/xxx/cassandra.py", line 4, in <module>
import cassandra.cluster
ModuleNotFoundError: No module named 'cassandra.cluster'; 'cassandra' is not a package
Using a different filename, the error disappears:
echo 'import cassandra.cluster' > tmp.py && python3 cassandra.py
So, for me, the error was that my own program overrode the package. O.o
I am trying to import 'multiprocessing' and using python 3.5.3 but its gives error
Traceback (most recent call last):
File "ssser.py", line 7, in <module>
import mutiprocessing
ImportError: No module named 'mutiprocessing'
when i try to install multiprocessing module then i again error occure
i am using following command for installation
python3 -m pip install multiprocessing
and got error
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-build-26ilgzih/multiprocessing/setup.py", line 94
print 'Macros:'

SyntaxError: Missing parentheses in call to 'print'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-26ilgzih/multiprocessing/
however when i import "import multiprocessing" in terminal then no error occure but when i used in my file "ssscr.py" then it gives error
i am using geany,and python3 (IDEL) on raspberry pi3
Can any body help me how i can fix this error ?
For others who faces Similar error like
ModuleNotFoundError: No module named 'multiprocessing';
would also occur if you name your python file as multiprocessing.(as it makes ambiguity between your program name and actual module name)
Just rename your file and it will work (if you have dependency installed).
Seems like you are installing multiprocessing in the python 2 version. Could you use pip3 to install the package?
pip3 install multiprocessing
Also use the following command to check which pip you are using
$ ls -l `which pip`
$ ls -l `which pip3`
And to see if the package got correctly installed or not use
$ pip show pip
$ pip3 show pip
Update:
multiprocessing is built-in after python2.6
OP did a typo. It should be
import multiprocessing in place of import mutiprocessing
I've been trying to install pyautogui for Python 3.4 on my Raspberry Pi 3 for the last 2 hours... I need it because I wrote a touch keyboard application that needs to run on it. On my main machine (elementary OS 0.4 with Python 3.5) I was able to install it without any problems. First I tried sudo pip install pyautogui but that only installed the Python 2.7 version of pyautogui. Of course next I tried sudo pip3 install pyautogui but that gave me this error:
Running setup.py (path:/tmp/pip-build-hf289jja/pyautogui/setup.py) egg_info for package pyautogui

Cleaning up...
Command python setup.py egg_info failed with error code 1 in /tmp/pip-build-hf289jja/pyautogui
Storing debug log for failure in /root/.pip/pip.log
... sorry for the formatting of the above, I couldn't get it to stay inside one code box.
I have no idea what module "new" is. I tried everything else under the sun, such as installing from the official resources: https://pypi.python.org/pypi/PyAutoGUI and various other guides, with NO results.. I'm kinda loosing my mind right now.
ANY Help is grately appreciated :)
Try the following:
sudo pip3 install python3-xlib
sudo pip3 install pyautogui
This assumes you have some other python3 libraries already installed, but you will see missing installs in the above if not.
I have installed leptonica and tesseract in $HOME/local and tesseract is working properly, then tesserocr python package with:
CPPFLAGS="-I/home/user/local/include /home/user/local/lib" pip install tesserocr
and when I want to invoke it I get this:
$ python3 extract.py
Traceback (most recent call last):
File "extract.py", line 4, in <module>
from tesserocr import PyTessBaseAPI, RIL, PyLTRResultIterator, iterate_level
ImportError: liblept.so.5: cannot open shared object file: No such file or directory
please help
As mentioned in my comment on the original post, the proper installation command should be:
CPPFLAGS="-I/home/user/local/include -L/home/user/local/lib" pip install tesserocr
