how to import h5py on datalab? - gcloud

Does anybody know how to install h5py on datalab? pip install h5py doesn't work. apt-get install python-h5py is working in the shell but it doesn't recognize the package in datalab notebook!
Thnaks

It is true that !pip install h5py wil allow you to install the library but unfortunately, even after a successful installation, the import will fail:
The issue is rooted on an ongoing python-future issue ("surrogateescape handler broken when encountering UnicodeEncodeError") that is experienced in datalab because the underlying OS uses an 'ANSI_X3.4-1968' file system encoding.
As a hacky workaround, you may remove line 60 from h5py's __init__.py by running the following command from within a notebook cell:
!sed -i.bak '/run_tests/d' /usr/local/lib/python2.7/dist-packages/h5py/__init__.py

Just make sure you run it using bash syntax: !pip install h5py in any notebook cell.

How can i use PIL in python?

I have successfully installed Pillow:
chris#MBPvonChristoph sources % python3 -m pip install --upgrade Pillow
Collecting Pillow
Using cached Pillow-9.0.1-1-cp310-cp310-macosx_11_0_arm64.whl (2.7 MB)
Installing collected packages: Pillow
Successfully installed Pillow-9.0.1
but when i try to use it in pycharm got:
Traceback (most recent call last):
File "/Users/chris/PycharmProjects/pythonProject2/main.py", line 1, in
from PIL import Image
ModuleNotFoundError: No module named 'PIL'
or using in Blender i got:
ModuleNotFoundError: No module named 'PIL'
I am not a python lib installing pro...so obviously i made something wrong. But how do i fix that?
Maybe i have to say i am working on a M1 Macbook
looks like you may need to repoint your pycharm to your installed python interpreter.
go to command line and find out python interpreter path. On windows you can where python in your command line an it will give you where your python and packages are installed.. You could also activate python directly in command line and find paths from there. For example, open command line then;
python
press enter = activates python
within then you can do:
import sys
for x in sys.path: x
In pycharm make sure you point to path discovered from step 1 and select that to be your python interpreter within pycharm --- check out examples here https://www.jetbrains.com/help/pycharm/configuring-python-interpreter.html#add-existing-interpreter
Should work. Not sure about all the steps you took, but if you installed python with pycharm on top of your regular installation of python i would recommend :
finding all the paths from step 1
deleting python using system
checking if folders found from paths step still exist
if they do, delete those as well
start over just with one python installation
repoint to that in pycharm
first
pip uninstall PIL
after uninstall
python3 -m pip install --upgrade pip
python3 -m pip install --upgrade Pillow
or
brew install Pillow

How to execute the right Python to import the installed tensorflow.transform package?

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)
<ipython-input-3-26a4792d0a76> in <module>()
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

Import Error on conda even directory exists

Environment info: Anaconda, windows7x64, py3.5
I setup a virtual env named as menpo to run menpoproject. For a long time I was using load_dlib_frontal_face_detector smoothly. After tinkering with a pip-install dlib command accidentally on virtualenv (I mean via Anaconda Prompt menpo) , I couldn't get my code working due to an "ImportError" ImportError: cannot import name' load_dlib_frontal_face_detector'. Code is like below:
import cv2
import menpo.io as mio
import menpodetect
Throws error at line 3.
There is this guy seems to had a similar issue.
https://github.com/menpo/menpodetect/issues/15
I did all the
conda remove dlib -y
pip uninstall dlib
conda install -c conda-forge dlib
stuff but still got the same error. Besides that;
Uninstalled Anaconda completely
Removed all Python folders wherever I found.
Installed Anaconda and setup a new menpo virtual env and still no luck. It seems like this dlib installation I made causing some issues. BTW, conda list produces dlib 18.18 py35_2 menpo and there is no pip line as mentioned in the link given above.
Wrong alarm. Seems that I've named my py file as menpodetect which I shouldn't do. Problem solved.

Unable to import module in Google Colab after installing

I was trying to clone and install the Google Unrestricted adversarial examples repository following the instructions provided here. But I am unable to import the any of the modules. First I cloned the repository and changed to that directory.
!git clone https://github.com/google/unrestricted-adversarial-examples.git
cd unrestricted-adversarial-examples
Then I used the pip install command.
!pip -e install bird-or-bicycle
The installation completed without any error. However, when I try to import I get the 'module not found error'. Could anyone tell me what I am doing wrong? I tried the same commands on my PC and it works.
import bird_or_bicycle
ModuleNotFoundError: No module named 'bird_or_bicycle'
I just got the solution after posting an issue to the repository. The solution was simple, all I needed to do was restart the Colab kernel (Restart Runtime option in the Runtime tab) after !pip -e install bird-or-bicycle Apparently that is required to pick up the newly installed package.
If you look at the bird-or-bicycle docs, you see that there is a data download step required after you pip install.
If you follow the instructions there and run the following in a notebook cell, then the import will work:
!git clone https://github.com/google/unrestricted-adversarial-examples
!pip install -e unrestricted-adversarial-examples/bird-or-bicycle
!bird-or-bicycle-download

Install BeautifulSoup, mrjob, pattern, and seaborn on python 2.7 on Jupyter

I am learning how to use the new Jupyter. I want to install packages:BeautifulSoup, mrjob, pattern, and seaborn on python 2.7. I first tried to do so by running pip install BeautifulSoup mrjob pattern seaborn That all returns: SyntaxError: invalid syntax
I also tried from bs4 import BeautifulSoup, it did work for Beautifulsoup. But I still don't know how to install other packages.
Wondering anyone know why there was syntax error for using pip install? Is that because I haven't installed pip on python 2.7?
I was also able to install these packages from iphython notebook window by running
import pip
def install(package):
pip.main(['install', package])
install('BeautifulSoup4')
Have you tried installing one package at a time. This helps you find which installation command not working.
You can find Julia packages here.
The problem was I was running pip from inside Jupyter. However, Jupyter is a command line program. Thanks to Mwaskom, the solution is run it from a terminal using:
pip install BeautifulSoup mrjob pattern seaborn
You could try:
!pip install BeautifulSoup mrjob pattern seaborn
