I am right now using the mac and trying to use the module pypng. I have installed the module from pip install pypng. It works well. However when I run my application python test.py (where inside test.py has 'import png'), it gives me a error saying 'ImportError:No module named png'.
However when I go into the python environment from command line, I type 'import png', it works without a error, why is that. I even restart the computer, but still in trouble.
when I installed pypng module, it tells me it is install in /Users/abc1/anaconda/lib/python2.7/site-packages, where inside this directory I can find the png.py and png.pyc.
when i print sys.path, this is the output, looks like it didn't load the png package from /Users/abc1/anaconda/lib/python2.7/site-packages. how do i solve it

Maybe you installed png to your python environment in the command line but not the environment you run your script. Try to use python batch.py in command line, or append /Users/abc1/anaconda/lib/python2.7/site-packages to sys.path.
Do you have a directory in your project that is named png? If so python will try to import it instead of the actual module

I know there has been similar problems, but unfortunately most of them are related to errors with pyperclip itself instead of the batch file, which i suspect is where the problem stems from.
Below is an MRE of my Python script:
#! python3 -> Do I have to use my version(3.8)?
# pw.py - An insecure password locker program.
import sys, pyperclip
#do something with the module
And my batch file pw.bat:
#py.exe C:\Users\KEVIN\PycharmProjects\atbs_exercise\pw.py %*
#pause
I am running python 3.8 on windows 10. I imported the pyperclip module in my python script pw.py and ran the file via pw.bat, and this in turn gives me this error:
Traceback (most recent call last):
File "C:\Users\KEVIN\PycharmProjects\atbs_exercise\pw.py", line 7, in <module>
import sys, pyperclip
ModuleNotFoundError: No module named 'pyperclip'
Press any key to continue . . .
Which shouldn't happen as I have installed pyperclip on the project using pip, and the script itself runs just fine in pycharm. What am I missing?
EDIT: I forgot to mention that I am using pycharm. So the thing is that pycharm had also installed python.exe in the project folder. And as the module pyperclip is only installed to that folder, the python.exe used in the bat must point to the one in the project folder.
i don't know why are you using py.exe. when running commands from a batch file or cmd .you should use python.exe.obviously you would need to add python to add for doing so.instead of adding py.exe to path,add python in system variable Path which is somewhere present in C:\Users\[username]\AppData\Local\Programs\Python\(your path might be diffrernt).you can add python in Path by following this post
after adding python to path just use the following batch-file:
#echo off
python path-to-your-py-file\filename.py
I am trying to install pdfMiner to work with CollectiveAccess. My host (pair.com) has given me the following information to help in this quest:
When compiling, it will likely be necessary to instruct the
installation to use your account space above, and not try to install
into the operating system directories. Typically, using "--
home=/usr/home/username/pdfminer" at the end of the install command
should allow for that.
I followed this instruction when trying to install.
The result was:
running install
running build
running build_py
running build_scripts
running install_lib
running install_scripts
changing mode of /usr/home/username/pdfminer/bin/latin2ascii.py to 755
changing mode of /usr/home/username/pdfminer/bin/pdf2txt.py to 755
changing mode of /usr/home/username/pdfminer/bin/dumppdf.py to 755
running install_egg_info
Removing /usr/home/username/pdfminer/lib/python/pdfminer-20140328.egg-info
Writing /usr/home/username/pdfminer/lib/python/pdfminer-20140328.egg-info
I don't see anything wrong with that (I'm very new to python), but when I try to run the sample command $ pdf2txt.py samples/simple1.pdf I get this error:
Traceback (most recent call last): File "pdf2txt.py", line 3, in <module>
from pdfminer.pdfdocument import PDFDocument ImportError: No module named pdfminer.pdfdocument
I'm running python 2.7.3. I can't install from root (shared hosting). The most recent version of pdfminer, which is 2014/03/28.
I've seen some posts on similar issues ("no module named. . . " but nothing exactly the same. The proposed solutions either don't help (such as installing with sudo - not an option; specifying the path for python (which doesn't seem to be the issue), etc.).
Or is this a question for my host? (i.e., something amiss or different about their setup)
I had an error like this:
No module named 'pdfminer.pdfinterp'; 'pdfminer' is not a package
My problem was that I had named my script pdfminer.py which for the reasons that I don't know, Python took it for the original pdfminer package files and tried to compiled it.
I renamed my script to something else, deleted all the *.pyc file and __pycache__ directory and my problem was solved.
use this command worked for me and removed the error
pip install pdfminer.six
Since the package pdfminer is installed to a non-standard/non-default location, Python won't be be able to find it. In order to use it, you will need to add it to your 'pythonpath'. Three ways:
At run time, put this in your script pdf2txt.py:
import sys
# if there are no conflicting packages in the default Python Libs =>
sys.path.append("/usr/home/username/pdfminer")
or
import sys
# to always use your package lib before the system's =>
sys.path.insert(1, "/usr/home/username/pdfminer")
Note: The install path specified with --home is used as the Lib for all packages which you might want to install, not just this one. You should delete that folder and re-install with --
home=/usr/home/username/myPyLibs (or any generic name) so that when you install other packages with that install path, you would only need the one path to add to your local Lib to be able to import them:
import sys
sys.path.insert(1, "/usr/home/username/myPyLibs")
Add it to PYTHONPATH before executing your script:
export PYTHONPATH="${PYTHONPATH}:/usr/home/username/myPyLibs"
And then put that in your ~/.bashrc file (/usr/home/username/.bashrc) or .profile as applicable. This may not work for programs which are not executed from the console.
Create a VirtualEnv and install the packages you need to that.
I have a virtual environment and I had to activate it before I did a pip3 install to have the venv see it.
source ~/venv/bin/activate
When executing script from command line, I got the following error
ImportError: No module named SubPackage3.MyClass
My package is structured as
TopLevelPackage
..SubPackage1
..SubPackage2
..SubPackage3
..__init_.py
..README.md
python (/usr/bin/python)
From other posts it seems that the problem is that the system does not recognize the path to SubPackage3. I have a separate __init_.py in each of the SubPackage, and print(sys.path) gave me
/home/shaunz/workspace/TopLevelPackage/SubPackage1
/home/shaunz/workspace/TopLevelPackage
/usr/lib/python2.7
....
Notice that only Package 1 is in the list of paths recognized. Any idea why this may be the case? And how do I change it?
I'm trying to run a module in SubPackage2. I'm using Eclipse.
Thanks
I want to compile my python code to binary by using pyinstaller, but the hidden import block me. For example, the following code import psutil and print the CPU count:
# example.py
import psutil
print psutil.cpu_count()
And I compile the code:
$ pyinstaller -F example.py --hidden-import=psutil
When I run the output under dist:
ImportError: cannot import name _psutil_linux
Then I tried:
$ pyinstaller -F example.py --hidden-import=_psutil_linux
Still the same error. I have read the pyinstall manual, but I still don't know how to use the hidden import. Is there a detailed example for this? Or at least a example to compile and run my example.py?
ENVs:
OS: Ubuntu 14.04
Python: 2.7.6
pyinstaller: 2.1
Hi hope you're still looking for an answer. Here is how I solved it:
add a file called hook-psutil.py
from PyInstaller.hooks.hookutils import (collect_data_files, collect_submodules)
datas = [('./venv/lib/python2.7/site-packages/psutil/_psutil_linux.so', 'psutil'),
('./venv/lib/python2.7/site-packages/psutil/_psutil_posix.so', 'psutil')]
hiddenimports = collect_submodules('psutil')
And then call pyinstaller --additional-hooks-dir=(the dir contain the above script) script.py
pyinstall is hard to configure, the cx_freeze maybe better, both support windows (you can download the exe directly) and linux. Provide the example.py, In windows, suppose you have install python in the default path (C:\\Python27):
$ python c:\\Python27\\Scripts\\cxfreeze example.py -s --target-dir some_path
the cxfreeze is a python script, you should run it with python, then the build files are under some_path (with a lot of xxx.pyd and xxx.dll).
In Linux, just run:
$ cxfreeze example.py -s --target-dir some_path
and also output a lot of files(xxx.so) under some_path.
The defect of cx_freeze is it would not wrap all libraries to target dir, this means you have to test your build under different environments. If any library missing, just copy them to target dir. A exception case is, for example, if your build your python under Centos 6, but when running under Centos 7, the missing of libc.so.6 will throw, you should compile your python both under Centos 7 and Centos 6.
What worked for me is as follows:
Install python-psutil: sudo apt-get install python-psutil. If you
have a previous installation of the psutil module from other
method, for example through source or easy_install, remove it first.
Run pyinstaller as you do, without the hidden-import option.
still facing the error
Implementation:
1.python program with modules like platform , os , shutil and psutil
when i run the script directly using python its working fine.
2.if i build a binary using pyinstaller. The binary is build successfully. But if i run the binary iam getting the No module named psutil found.I had tried several methods like adding the hidden import and other things. None is working. I trying it almost 2 to 3 days.
Error:
ModuleNotFoundError: No module named 'psutil'
Command used for the creating binary
pyinstaller --hidden-import=['_psutil_linux'] --onefile --clean serverHW.py
i tried --additional-hooks-dir= also not working. When i run the binary im getting module not found error.
When debugging my "google dobule click exchange testing script", it runs successfully on a Python Terminal, but when doing so with the eclipse pydev IDE, the following line give me an error:
import realtime_bidding_pb2
The error I'm getting is
ImportError: No module named realtime_bidding_pb2
I know this module is outsourced, but I don't know where it is or how to import it into the eclipse pydev IDE.
If you use unix like OS, change directory to the directory where the files requester.py, Makefile, realtime-bidding.proto (from requester.tar.gz) and execute command 'make' in shell. realtime_bidding_pb2 file will be created.
Next you get "ImportError: No module named google.protobuf". You need install python-protobuf (command 'apt-get install python-protobuf' for Ubuntu, you should be root).
Uses requester.py by command like 'python requester.py --url= --max_qps=1 --seconds=20'.
