I'm a total newbie in python and I was just trying to do some simple climate statistics withthe spyder environment of anaconda.
I import the climate-indices package from the anaconda prompt.
When I want to import the "spi" function from the package,I have the following import error:
cannot import name 'spi' from 'climate_indices'
Any idea?
Ty
It seems that it is not able to find the function....

I am building a QGIS plugin and I'd like to import a module named python-ternary. I have a specific issue importing this module (others get imported), and importing it in QGIS (works outside of QGIS).
I installed it using pip, tried to import it outside of QGIS, works fine.
Now writing this in my plugin main file:
from qgis.PyQt.QtCore import QSettings, QTranslator, QCoreApplication, Qt
from qgis.PyQt.QtGui import QIcon, QColor
from qgis.PyQt.QtWidgets import QAction, QApplication
from .resources import *
import psycopg2
import ternary
I get this when loading my plugin with the QGIS plugin manager:
QGIS error when loading the plugin
Now the python-ternary module is well installed in lib\site-packages:
ternary file in lib\site-packages
And lib\site-packages is on path as shown in the QGIS error.
I have no problem importing other modules in QGIS e.g. psycopg2 is imported without issue. I force reinstalled python-ternary with pip, to no avail.
Is there a compatibility issue with this particular module I'm not aware of ?
I am trying to use the calc module in metpy. I have installed it both via pip and 'conda forge' option. When i run my script in spyder, i get the following error
ImportError: cannot import name 'AuthorityMatchInfo' from 'pyproj._crs' eg Example file path : (~anaconda3/lib/python3.7/site-packages/pyproj/_crs.cpython-37m-x86_64-linux-gnu.so)
Had the same issue two times and solved it by following advice I found on github.
Basically one needs to uninstall pyproj and reinstall.
I have a problem. When writing the "pip install pyowm" command to the console, the module is installed, but the system doesn't see it. For example, Phyton, when executing the command "impor pyowm", gives an error, and when writing the command "pyowm" to the console, the error "" pyowm " is not an external or internal command".
All of the above apply to other modules as well.
P.S. I use VS Code and Python v.3.8.3
From https://github.com/csparpa/pyowm:
from pyowm import OWM
The package name (pyowm) and the module name (OWM) do not necessarily need to correspond.
You can't just use any tool just by name from the console.
You have to first enter python to the console and then try import pyowm again.
It should import pyowm. But later you may want to actually use pyowm. Then you use this import most of the time:
from pyowm.owm import OWM
I've installed keras-rl package on my computer, using their instructions:
git clone https://github.com/matthiasplappert/keras-rl.git
cd keras-rl
python setup.py install
So my conda environment sees this package, however when I am trying to import it in Spyder as a part of my code, i.e. import keras-rl, I get the following error:
SyntaxError: invalid syntax
with a pointer to the dash of keras-rl.
Question: How could I import the keras-rl (or any other package with the dash in the name) in Spyder?
We can install keras-rl by simply executing
pip install keras-rl
There are various functionalities from keras-rl that we can make use for running RL based algorithms in a specified environment
few examples below
from rl.agents.dqn import DQNAgent
from rl.policy import BoltzmannQPolicy
from rl.memory import SequentialMemory
This is how we can use the package.
If you look at the examples present in the github repository, you will see that the various functionalities are imported from rl. Like this:
(root) ~/condaexpts/keras-rl/examples $ grep -h import * | grep rl
from rl.agents import ContinuousDQNAgent
from rl.memory import SequentialMemory
from rl.random import OrnsteinUhlenbeckProcess
from rl.core import Processor
from rl.agents.cem import CEMAgent
from rl.memory import EpisodeParameterMemory
from rl.agents import DDPGAgent
from rl.memory import SequentialMemory
from rl.random import OrnsteinUhlenbeckProcess
from rl.agents.dqn import DQNAgent
from rl.policy import LinearAnnealedPolicy, BoltzmannQPolicy, EpsGreedyQPolicy
from rl.memory import SequentialMemory
from rl.core import Processor
from rl.callbacks import FileLogger, ModelIntervalCheckpoint
from rl.agents.dqn import DQNAgent
from rl.policy import BoltzmannQPolicy
from rl.memory import SequentialMemory
I had the same problem. After lots of examination I found the correct way.
You can import RL by writing this:
"import rl"
and then write your code like:
rl.core.Agent()
First of all I'm aware of the question here but I couldn't find a satisfied answer there. I don't want to ignore errors or use comments - I want to have the right settings in eclipse/pydev. My problem is pretty similar to this one.
I'm using Ubuntu 12.04 and installed a virtuenv for python 2.7 in my home directory. After installing several python packages (numpy, scipy, matplotlib, etc.) using pip, I installed eclipse 4.3 with pydev.
If I use the python system interpreter at /usr/bin/python everything works fine (except that I didn't want to use). However, if I try to set up a python interpreter using the virtualenv first I get this warning describe here. After clicking "proceed anyway", it seems to work. So far so good.
However e.g. import numpy as np gives for each np.* call the eclipse/pydev error Undefined variable from import, also the code completion doesn't work properly. It seems to work, e.g. for datetime, but not for numpy, scipy and matplotlib.
Does anybody figured out to configure eclipse correctly?
I already tried to add the numpy path manually to the virtualenv interpreter, but than I get the weird error:
import matplotlib.dates as mpl_dates
