I am running Python 3.7.2 and using Miniconda3 to create a new environment named test-env. I have installed the pyarrow package from the default channel into this environment; however, when I try and import pyarrow, the Python interpreter gives me an undefined symbol error:
Import Error: /test-env/lib/python3.7/site-packages/pyarrow/lib.cpython-37m-x86_64-linux-gnu.so: undefined symbol: _ZNK5arrow6Status8ToStringB5cxx11Ev
From other threads on SO, I gather that this is due to a compiler incompatibility. I'm not a developer so I'm not sure how to fix this.
I had the same error after I installed by conda install, after I conda uninstall, I did pip install, the issue went away.
>>> import pyarrow

I would recommend opening a ticket at https://issues.apache.org/jira/projects/ARROW/issues/ARROW-4774?filter=allopenissues
Provide how you installed pyarrow (pip or conda), which distribution of linux. If you can reproduce this in a clean environment, even better.

I'm attempting to install xlsxwriter on CentOS centos-release-7-6.1810.2.el7.centos.x86_64
when I install xlsxwriter:
703404669#bioitutil2:~$ sudo pip3 install xlsxwriter
Requirement already satisfied: xlsxwriter in /usr/lib64/python3.4/site-packages (1.2.6)
and when I attempt to load the module, I get a contradictory message:

>>> import xlsxwriter
Traceback (most recent call last):

I've also tried pip3.6, but get more errors:

Traceback (most recent call last):
File "/bin/pip3.6", line 16, in <module>
sys.exit(main())
TypeError: 'module' object is not callable
How can I get python3 to find xlsxwriter?
pip3 install xlsxwriter
gives you
Requirement already satisfied: xlsxwriter in /usr/lib64/python3.4/site-packages (1.2.6)
so it is installed for python3.4, but python3 calls Python 3.6.8, so two different python versions that have their seperate site-package directory.
You can avoid this problem by doing python3 -m pip install, which should
Make sure that you are installing exactly for the python version you are intending to use
Avoid the 'module' object is not callable error
Note
I don't know how you ended up having two python versions, but it might be worth to check if you can uninstall one of them and then use a virtual environment or similar to manage multiple python versions on your system
No module named matplotlib after installing
I have already installed matplotlib using >> pip3 install matplotlib. As I'm using the latest version of python 3.8.0.
Even updated the PIP to the latest version
After selecting import matplotlib, it says " No module named matplotlib"
While if I tried to install again received message

try pip3 install matplotlib so that it installs it on python3 instead of python2
update: not sure If that's how it works on Windows though, it certainly is on Linux.
Unable to import flask-migrate dependencies that are missing python version/sub-version from build version (3rd column of conda list output).
Flask-migrate was installed from conda-forge using:
conda install -c conda-forge flask-migrate
Several dependencies were installed simultaneously and are found in conda list -n venv but cannot be imported to python.

>>> import alembic
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'alembic'
From what I have found, the packages that are raising ModuleNotFoundErrors upon import are all missing the python version in the 3rd column of conda list.
Successfully import: py36_0 or py36_1000 or py36* etc.
ModuleNotFoundError: py_0 or py_1
Why are installed packages raising ModuleNotFoundError when imported to python?
I believe the packages with py_0 environment were all installed as Noarch packages from conda. I'm not sure why my system is unable to import the Noarch packages but I was able to work around the problem by manually downloading the win64-py36_0.tar.bz2 files and installing them locally using:
conda install /package-path/package-filename.tar.bz2
I am installing anaconda environment with keras, and using theano backend. But I cannot get theano to work. here is what I have done and also errors noted afterwards.
Step 1: download the latest version of anaconda, then install in linux by ' bash Anaconda3-5.0.1-Linux-x86_64.sh'
Step 2: conda install -c conda-forge keras, which installs keras 2.0.9
This also installs theano 1.0.1, as shown below:
The following NEW packages will be INSTALLED:
keras: 2.0.9-py36_0 conda-forge
libgpuarray: 0.7.5-0 conda-forge
mako: 1.0.7-py36_0 conda-forge
pygpu: 0.7.5-py36_0 conda-forge
theano: 1.0.1-py36_1 conda-forge
The following packages will be SUPERSEDED by a higher-priority channel:
conda: 4.3.30-py36h5d9f9f4_0 --> 4.3.29-py36_0 conda-forge
conda-env: 2.6.0-h36134e3_1 --> 2.6.0-0 conda-forge
Next, testing theano:

>>> import theano
>>> theano.ifelse
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'theano' has no attribute 'ifelse'
The error shown in the last line is preventing me using theano and keras properly. all my code that works on a different platform does not work, because they will generate an error like that.
I also tried to follow instructions on http://deeplearning.net/software/theano/install_ubuntu.html with a fresh anaconda installation to just install theano, without keras. But after installation, with the testing line above, I get the same error.
Any suggestion on how to fix this?
It is not import by default.
Try to use
import theano.ifelse
I am migrating a Python program from 2.10 to 3.6. The packages scikits.talkbox is part of it. However, I cannot figure out how to use it any more. The installation from pip seems to work fine but I cannot import it. Has anyone faced this problem before ?
