Despite all my efforts, I wasn't able to install the R kernel for my IPython/Jupyter notebook on Canopy.
I've closely followed the clear instructions given in:
http://www.michaelpacer.com/maths/r-kernel-for-ipython-notebook
(or, alternatively, http://irkernel.github.io/installation/)
All goes well until the last step that install the kernel on Jupyter:
IRkernel::installspec()
Here is the weird message I get:
File "/Users/julien/Library/Enthought/Canopy_64bit/User/bin/jupyter-kernelspec", line 8
from jupyter_client.kernelspecapp import KernelSpecApp.launch_instance
^
SyntaxError: invalid syntax
My configuration is the following:
Macbook with El Capitan
R version 3.2.2
IPython 4.0.1
Jupyter 4.0.6
It turns out that the file "jupyter-kernelspec " was corrupted for some reason. I replaced it by the following code:
#!/usr/bin/env python
from jupyter_client.kernelspecapp import KernelSpecApp
def main():
KernelSpecApp.launch_instance()
if __name__ == '__main__':
main()
It solved my issue.

I have a functioning PyTorch installation with a conda environment with MPS backend working fine on a M1 mac.
However, after installing torchvision, when I try to import torchvision, I get this error (also shown in screenshot):
ImportError: cannot import name 'PILLOW_VERSION' from 'PIL' (/opt/anaconda3/lib/python3.9/site-packages/PIL/__init__.py)
In the screenshot below, I run python in my terminal and then try to import torchvision and get the error.
I have navigated to and opened the file in question __init__.pyin the PIL folder, and the file itself is empty.
If relevant:
torch version is 1.13.0.dev20220911
Python is 3.9.13
Conda is 22.9.0
I have tried installing and reinstalling with conda and pip multiple times but with the same result when importing torchvision.
I found this stackoverflow question about PILLOW_version, which got me to try to rename the __init__.py file that turned out to be empty, which I did not expect, since that made it impossible to rename the pillow versioning.
Thanks in advance.
I encountered an import problem by PyAudio.
I have a winodws 10, 64 bit, and use Anaconda and Spyder IDE with python 3.7.
I installed PyAudio in Ananconda, ran as administrator, with these commands :
cd
conda install -c conda-forge PyAudio
The installation ran without any problems.
I then restarted both Anaconda and SPYDER. PyAudio now shows up in Anaconda's list of installed packages.
When I try to import Pyaudio in Spyder (IPython console), I encounter this error message :
[1]: import pyaudio
Could not import the PyAudio C module '_portaudio'.
Traceback (most recent call last):
File "", line 1, in
import pyaudio
File "C:\ProgramData\Anaconda3\lib\site-packages\pyaudio.py", line 116, in
import _portaudio as pa
ImportError: DLL load failed: The specified module could not be found.
I tried to fix it by answers to similar ImportError message issued, while other users tried to import other packages like SKlearn ... , but with no success.
Your problem (and mine) are the same. The issue is, unfortunately, the version of python you're running (in tandem with your OS).
Check out this link:
https://people.csail.mit.edu/hubert/pyaudio/#:~:text=Note%3A%20As%20of%20this%20update,4.
Under the INSTALLATION section in the link for WINDOWS, PyAudio's latest version (0.2.11) is compatible with Python versions: 2.7, 3.4, 3.5, 3.6.
My current python is 3.8.5, so you (and I) could never use PyAudio unless they added compatibilities or we revert to an above python version.
I tried to install portaudio using
conda install portaudio
but it seems like it didn't work as it should be. However,
conda install -c anaconda portaudio
solved the problem.
see the official anaconda page
The version of my Python is 2.7.13.
I run the following in Jupyter Notebook.
Firstly, I installed the packages
%%bash
pip uninstall -y google-cloud-dataflow
pip install --upgrade --force tensorflow_transform==0.15.0 apache-beam[gcp]
Then,
%%bash
pip freeze | grep -e 'flow\|beam'
I can see that the package tensorflow-transform is installed.
apache-beam==2.19.0
tensorflow==2.1.0
tensorflow-datasets==1.2.0
tensorflow-estimator==2.1.0
tensorflow-hub==0.6.0
tensorflow-io==0.8.1
tensorflow-metadata==0.15.2
tensorflow-probability==0.8.0
tensorflow-serving-api==2.1.0
tensorflow-transform==0.15.0
However when I tried to import it, there are warning and error.
WARNING:tensorflow:From /usr/local/lib/python2.7/dist-packages/tensorflow_estimator/python/estimator/api/_v1/estimator/__init__.py:12: The name tf.estimator.inputs is deprecated. Please use tf.compat.v1.estimator.inputs instead.
ImportErrorTraceback (most recent call last)

1 import tensorflow as tf
----> 2 import tensorflow_transform as tft
3 import shutil
4 print(tf.__version__)
ImportError: No module named tensorflow_transform
After some investigation, I think I have some ideas of the problem.
I run this:
%%bash
pip show tensorflow_transform| grep Location
This is the output
Location: /home/jupyter/.local/lib/python3.5/site-packages
I tried to modify the $PATH by adding /home/jupyter/.local/lib/python3.5/site-packages to the beginning of $PATH. However, I still failed to import tensorflow_transform.
Based on the above and the following information, I think, when I ran the import command, it executes Python 2.7, not Python 3.5
import sys
print('\n'.join(sys.path))
/usr/lib/python2.7
/usr/lib/python2.7/plat-x86_64-linux-gnu
/usr/lib/python2.7/lib-tk
/usr/lib/python2.7/lib-old
/usr/lib/python2.7/lib-dynload
/usr/local/lib/python2.7/dist-packages
/usr/lib/python2.7/dist-packages
/usr/local/lib/python2.7/dist-packages/IPython/extensions
/home/jupyter/.ipython
Also,
import sys
sys.executable
'/usr/bin/python2'
I think the problem is tensorflow_transform package was installed in /home/jupyter/.local/lib/python3.5/site-packages. But when I run "Import", it goes to /usr/local/lib/python2.7/dist-packages to search for the package, rather than /home/jupyter/.local/lib/python3.5/site-packages, so even updating $PATH does not help. Am I right?
I tried to upgrade my python, but
%%bash
pip install upgrade python
Defaulting to user installation because normal site-packages is not writeable
Then, I added --user. It seems that the python is not really upgraded.
%%bash
pip install --user upgrade python
%%bash
python -V
Python 2.7.13
Any solution?
It seems to me that your jupyter notebook is not using the right python environment.
Perhaps, you installed the package under version 3.5,
but the Notebook uses the other one, thus it cannot find the library
You can pick the other interpreter by clicking on: Python(your version) - bottom left.
VS-Code - Select Python Environment 1
However you can do this also via:
CNTRL+SHIFT+P > Select Python Interpreter to start Jupyter Server
If that does not work make sure that the package you are trying to import is installed under the correct python environment.
If not open up a terminal, activate the environment and install it using:
pip install packagename
For example i did the same thing here: (Note: I'm using Anaconda)
installing tensorflow_transform
After a installation, you can import it in your code directly like this:
importing tensorflow_transform
I have tried running a ProcessImage.py file in which I import the package pytesseract in Jupiter Lab and VSCode.
This is the error that pops out :
import pytesseract
ImportError: No module named pytesseract
I already know that pytesseract is installed in my environment because with conda list:
pytesseract 0.3.2 py_0 conda-forge
pytest 5.3.5 py38_0 coda-forge
However, if I run my ProcessImage.py file on my local no error is prompted.
I know the error is related to paths in Jupiter Lab and VsCode but I can't seem to find a solution.
Have you tried to launch your python file using Ctrl+F5 command for run?
I had this same ImportError when trying to launch my python program using the .run extension. It persistently started python 2.7 while my environment was using Python3. I first thought that it was a VS code error but it wasn't.
I have seen many more or less related questions on this topic, but none helped me finding a way to solve my problem.
I'm not very familiar with Windows environment, deep apologies if my question sounds obvious to some extent.
Setup:
Windows 10
Python 3.7.0 (installed through latest Anaconda release)
Spyder 3.3.1
Im running a Python, that involves several modules import. I came across some module issues. For example:
from PIL import Image as PIL_Image
Works smooth in Spyder, but gives (error message in french but I guess you got the point):
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Users\my_user_name\Anaconda3\lib\site-packages\PIL\Image.py", line 64, in <module>
from . import _imaging as core
ImportError: DLL load failed: Le module spécifié est introuvable.
If executed in Powershell or cmd.
What I tried:
Appending Anaconda's install path to my path variable before I open Powershell:
$Env:path += ";C:\Users\my_user_name\Anaconda3;C:\Users\my_user_name\Anaconda3\Scripts"
Checking that sys.path is the same in Powershell and Spyder. For both, it looks like:
['',
'C:\\Users\\my_user_name',
'C:\\Users\\my_user_name\\Anaconda3\\python37.zip',
'C:\\Users\\my_user_name\\Anaconda3\\DLLs',
'C:\\Users\\my_user_name\\Anaconda3\\lib',
'C:\\Users\\my_user_name\\Anaconda3',
'C:\\Users\\my_user_name\\AppData\\Roaming\\Python\\Python37\\site-packages',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\win32',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\win32\\lib',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\Pythonwin',
'C:\\Users\\my_user_name\\Anaconda3\\lib\\site-packages\\IPython\\extensions',
'C:\\Users\\my_user_name\\.ipython']
What else could explain that my import fails outside of Spyder ?
Ok I could not find a clean way out, so let me just share my experience in case someone finds it helpful ...
The DLL failure with PIL related libs seems to be a known issue. See further explanations:
https://github.com/python-pillow/Pillow/issues/2945
PIL: DLL load failed: specified procedure could not be found
How I solved my issue:
Cleanly uninstalled anything related to Python on my laptop. Both Anaconda, isolated Python installs, Spyder ...
Re-installed the latest Anaconda. It happens to come with Python 3.7.1 instead of 3.7.0
Re-did my PIP installs of everything. Note I had to append Anaconda\Library\bin to my Windows path for PIP to work completely, which I don't recall having done with my previous installation.
