In order to feed text strings stored in a .csv file into Google's named entity extractor, I would like to use the Google NLP API and pandas together.
I am currently using conda to manage my python environments.
These are the steps I have taken:
Part 1: Install google-cloud-language in conda environment
conda create —n myenv
conda activate myenv
pip install google-cloud-language
Run example program:
python language_entities_text.py
Output:
Representative name for the entity: California
Entity type: LOCATION
Salience score: 1.0
wikipedia_url: https://en.wikipedia.org/wiki/California
mid: /m/01n7q
Mention text: California
Mention type: PROPER
Mention text: state
Mention type: COMMON
Language of the text: en
So far so good. Google's example program works
Part 2: Install pandas and run the same program
conda install pandas
or
pip install pandas
Run the same program:
python language_entities_text.py
After I install pandas using conda or pip and run the same program, I get an error.
Error message:
"Traceback (most recent call last):
File "language_entities_text.py", line 28, in <module>
from google.cloud import language_v1
ModuleNotFoundError: No module named 'google'
What is going on? Is there a conflict between google-cloud-language and pandas? How can I get both libraries to work together? Ideally, I would like to keep using conda because that is what I am familiar with but is conda the problem?

I am running on windows 10. I am having problems with importing TensorFlow. I am in Vs code. I installed tensorflow using pip3. And here is the error:
Traceback (most recent call last):
File "c:/Users/USER/PycharmProjects/tt/main.py", line 1, in <module>
import tensorflow as tf
ModuleNotFoundError: No module named 'tensorflow'
I created my project in pycharm.
I am using python 3.7.5 and TensorFlow 2.0.0. This is how I installed TF:
pip3 install tensorflow==2.0.0
please help I was having this problem for a week.
Thanks , In Advance
For your work/project, please try to create a new virtual environment and then install all your required packages.
Like this:
$ python3 -m venv env
Activate it:
$ source env/bin/activate
and then install the tensorflow package inside your virtual environment:
pip3 install tensorflow
I think you need to create environment separate
and then install tensorflow..

Do you have several different python environments on your pc? Which python interpreter are you using when you install tensorflow?
The Status Bar will show you the current interpreter in the lower left corner. Check whether it is the same with the one you use when you install tensorflow.
enter image description here
I was getting your exact error, but this worked for me:
File->settings
Workspace tab
Search for "interpreter"
Put the complete path to the python.exe you want to execute under "default interpreter path"
It seems VSCode either found (or included) an older version of python that couldn't find the things I installed with pip.
I am a bit of a python newb and I'm guessing the venv approach is superior, but I couldn't get that cooperating with VSCode on windows.
I installed pandas library with Anaconda 1.7.2. When I try import it with python (version 2.7.16), the following error appears:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named pandas
My code in Anaconda is:
conda install pandas
And my code in Python is:
import pandas as pd
I have installed numpy library and import with python with no problem, for example. So I believe that Anaconda and Python are working well.
How can I solve this problem?
Since you installed Pandas with Anaconda, you have to run the python shell that is in anaconda environment. Whenever you just type python on the terminal, it will always run the default python. To change this, you need to change the path or use alias.
run
which python
This will give you the location where your default python is installed.
To change your default python to anaconda's python, refer to this link https://askubuntu.com/questions/886983/how-to-set-anaconda-as-a-default-python
If you do not want to change from default python to anaconda python, just run
pip install pandas
If you have pip, this will install pandas for the default python. Else install pip first.
!pip install
Or use Conda install SITE
And paste code...
I need to use netcdf but do not have install permission for python modules. I have downloaded netcdf-0.1.2.tar.gz from here: https://pypi.python.org/simple/netcdf/ and unzipped the tar ball. I have been following this stack overflow post in an attempt to use the module but have had no luck so far:
(Python) Use a library locally instead of installing it
here is what I have tried:
Installing virtualenv:
I do not have permission to do this
python setup.py install -- user:
again, I don't have permission
running my script with netcdf as my current working directory:
I tried this as well, here are the issues I have run into:
first I went into netcdf-0.1.2 and made a new file called asdf.py
which contains the following:
import netcdf
print("testing")
running python asdf.py gives the following error:
Traceback (most recent call last):
File "asdf.py", line 1, in <module>
import netcdf
File "/.../Downloads/netcdf-0.1.2/netcdf/__init__.py", line 1, in <module>
from netcdf import *
File "/.../Downloads/netcdf-0.1.2/netcdf/netcdf.py", line 1, in <module>
from netCDF4 import Dataset, numpy
ImportError: No module named netCDF4
I'm not sure how to fix this error, any help would be greatly appreciated
in case this is somehow relevant, the version of Linux I am using is 3.2.0-23-generic
also I have numpy installed already
Easest would be to install Anaconda or Miniconda with your user rights.
Anaconda already as netCDF4installed. In case of Miniconda install with:
conda install netcdf4
If you have Python 3 installed, then you will have the venv package in the standard library, so you do not need "virtualenv" to be installed for you separately (as would be the case with Python 2). Instead use python3 -mvenv , in a similar way to how you would use virtualenv, for example:
python3 -mvenv /path/to/my_venv
or to include any non-standard packages already installed on the system:
python3 -mvenv --system-site-packages /path/to/my_venv
After that, you should be able to activate the environment and pip install packages, e.g.
source /path/to/my_venv/bin/activate # for csh use activate.csh instead
pip install netCDF4
Remember to source the activate script at run time as well as installation time:
source /path/to/my_venv/bin/activate
python
and you should then find that in your python session you have the netCDF4 package available, e.g.
import netCDF4
my_dataset = netCDF4.Dataset('myfile.nc')
Of course, substitute the actual path in place of /path/to/my_venv above.
None of this requires any root privileges.
(And as someone else has suggested, another option for you is to use conda.)
I'd also like to highlight that the package is imported using capitals
import netCDF4 as nc
This might not matter on a mac, but for Windows it is key.
I'm trying to install NUMBA on a mac machine (10.12.6).
I've tried with CONDA:
conda install numba
I'm getting this:
Fetching package metadata ...........
Solving package specifications: .
# All requested packages already installed.
# packages in environment at /Users/lefaa/miniconda2:
#numba 0.35.0 np113py27_6
This seems good, however when I try (using python 2.7):
python -c "from numba import jit"
I'm getting that the numba module isn't installed:
Traceback (most recent call last):
File "<string>", line 1, in <module>
ImportError: No module named numba
Do I have to configure something else?
It is likely that your path is not set up correctly and the python that conda installed numba into is not the one you are running. If you run which python you should get the one that's in your miniconda2 if everything is working properly. If you get a different python executable then you probably need to set your PATH environment variable. See:
https://conda.io/docs/user-guide/install/index.html#installing-conda-on-a-system-that-has-other-python-installations-or-packages
I solved the issue. Indeed, when installing with conda, conda installs the target package in python associated to conda (i.e, in this python '/Users/lefaa/miniconda2/bin/python'). So to import numba, it is necessary to lunch the python of miniconda.
However, to install numba on the main python (python2.7), one solution will be to install like this '/usr/local/bin/pip2.7 install numba'.
I wrote myself a handy bash script, which solves the task of creating a virtualenv with its own compiled virtualenv and python. It aims at creating a mostly self contained virtualenv, with maybe only native libraries installed in system level if necessary, but installing all python packages and virtualenv and pip and such things inside the virtualenv.
The script can be found here.
I invoke the script as follows:
self_contained_venv.sh \
-n udacity_model_building_and_validation \
-p https://www.python.org/ftp/python/3.4.4/Python-3.4.4.tar.xz \
-v https://pypi.python.org/packages/c8/82/7c1eb879dea5725fae239070b48187de74a8eb06b63d9087cd0a60436353/virtualenv-15.0.1.tar.gz#md5=28d76a0d9cbd5dc42046dd14e76a6ecc \
-d pandas scikit-learn seaborn
Given the required packages for compiling python and virtualenv are installed on the system, the script creates a nice virtualenv. However, when I try to access any installed modules/packages from within the virtualenv, python is not able to find them. To demonstrate this, I'll put some output of commands and code here:
First of all of course I have to activate the virtualenv:
. bin/activate
output: None, works without problem.
Then I print the pythonpath python is aware of:
import sys
for i in sys.path:
print(i)
output:
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python34.zip
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/plat-linux
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/lib-dynload
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/plat-linux
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/site-packages
So far so good. Then I try to import a module / package I installed during usage of my bash script: pandas:
python
(IDLE is running)
import pandas as pd
output:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'pandas'
Another try:
import numpy as np
output:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named 'numpy'
Huh? So none of the packages is available? Lets check pip again:
which pip
output:
alias pip='localpython/bin/pip3.4'
./localpython/bin/pip3.4
Ok, so it's using my local pip.
Check packages:
pip list
output:
numpy (1.11.0)
pandas (0.18.1)
pip (8.1.2)
psutil (4.1.0)
Python-contrib-nbextensions (alpha)
python-dateutil (2.5.3)
pytz (2016.4)
PyYAML (3.11)
setuptools (18.2)
six (1.10.0)
virtualenv (15.0.1)
Hm the packages are there, so why can't python find them? Let's see where those packages are located, simply by trying to remove one:
pip uninstall pandas
output (shortened, because it fills many pages):
Uninstalling pandas-0.18.1:
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas-0.18.1-py3.4.egg-info
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__init__.py
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__pycache__/__init__.cpython-34.pyc
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__pycache__/_version.cpython-34.pyc
/home/xiaolong/development/Python/udacity_model_building_and_validation/localpython/lib/python3.4/site-packages/pandas/__pycache__/info.cpython-34.pyc
Aha, so the packages are in the path.
Another attempt on finding out if python looks in the right places:
>>> from distutils.sysconfig import get_python_lib
>>> print(get_python_lib())
/home/xiaolong/development/Python/udacity_model_building_and_validation/lib/python3.4/site-packages
So this one indicates it does not look in the right place, if I understand correctly.
Note:
The script does the following things, which might not be obvious:
compile python with a prefix (local python)
compile virtualenv for the local python
it aliases pip to the local pip of the version of the installed python
it aliases virtualenv to the locally installed one
it installs packages from pypi if specified
it updates the local pip if there is a newer version available
I am a beginner still at writing bash scripts, so I think the structure and logic of the script is fairly easy to understand. It also prints information about success of its operations in the terminal.
Further Notes:
I did not use su or sudo to run the script.
My OS is a Fedora 22, although I think in this case any major distro would work the same way.
OS has been updated recently.
Question: So why can't Python find them / its own packages? (What do I need to change?)
can you try to compare path to pyhton and pip in your script and manually in your system:
which python and which pip?
After that check pip freeze | grep pandas it should return you package ...if no you need to add this package to site-packages folder of you python.
