I'm trying to use weave with Python ANACONDA 64 bit. As weave requires Python 2.7 i created a new env to be able to import it, during code execution it turned out that libpython27.a is missing. So I created this library i.e. 1st created def file and later library with dll tool
C:\ProgramData\Anaconda3\envs\Python27>gendef python27.dll
C:\ProgramData\Anaconda3\envs\Python27>C:\MinGW64\bin\dlltool -v --dllname python27.dll --def python27.def --output-lib libpython27.a
library creation went OK however during comlipaton by weave i'm getting Symbol table not found. After a bit of debbuging here is a code which reject is complaining that in new python27.def there is no symbol file
File "C:\ProgramData\Anaconda3\envs\Python27\lib\site-packages\numpy\distutils\mingw32ccompiler.py", line 302, in generate_def
raise ValueError("Symbol table not found")
ValueError: Symbol table not found
def dump_table(dll):
st = subprocess.Popen(["objdump.exe", "-p", dll], stdout=subprocess.PIPE)
return st.stdout.readlines()
def generate_def(dll, dfile):
"""Given a dll file location, get all its exported symbols and dump them
into the given def file.
The .def file will be overwritten"""
dump = dump_table(dll)
for i in range(len(dump)):
if _START.match(dump[i].decode()):
break
else:
raise ValueError("Symbol table not found")
Any idea what it can be ??
After more investigations it looks like Anaconda distribution delivers msvcr90.dll without
symbol table. So when generate_def(dll, dfile) for msvcr90.dll in invoked it generates empty def file.
fix for it was in line 352 mingw32compiler.py to add return False
def build_msvcr_library(debug=False):
return False
if os.name != 'nt':
return False

I'm trying to fetch an instance to point to the already running AutoCAD 2016 application, or to create a new instance if it's not running.
Here's a simple code sample for that:
#Import needed modules
import os
import comtypes.client
from comtypes import COMError
from comtypes.client import CreateObject, GetModule, GetActiveObject
try:
acad = GetActiveObject("AutoCAD.Application.20")
print "AutoCAD is Active"
print "########"
except(OSError, COMError): #If AutoCAD isn't running, run it
acad = CreateObject("AutoCAD.Application.20",dynamic=True)
print "AutoCAD is successfuly Opened"
print "########"
When AutoCAD isn't running, the function CreateObject works successfully & only if dynamic is set to true .. but GetActiveObject throws the Traceback error
File "C:\Python27\lib\site-packages\comtypes\client\__init__.py", line 250, in CreateObject
return _manage(obj, clsid, interface=interface)
File "C:\Python27\lib\site-packages\comtypes\client\__init__.py", line 188, in _manage
obj = GetBestInterface(obj)
File "C:\Python27\lib\site-packages\comtypes\client\__init__.py", line 112, in GetBestInterface
interface = getattr(mod, itf_name)
AttributeError: 'module' object has no attribute 'IAcadApplication'
I've seen this but with no clue.
Also, I've returned to the documentation of comtypes, it says
The GetActiveObject function succeeds when the COM object is already running, and has registered itself in the COM running object table. Not all COM objects do this.
but this also doesn't give me any clue.
P.S GetActiveObject works well with me with other applications such as ETABS 2016 & SAP2000 v18
Any help & insightful responses will be totally appreciated, thanks in advance
It's weird but it does work (at least with me)
I went to the gen folder, its full path is C:\Python27\Lib\site-packages\comtypes\gen, then looked for the file AutoCAD.py, opened it in IDLE, knew its equivalent generated symbol (ID) such as _4E3F492A_FB57_4439_9BF0_1567ED84A3A9_0_1_0, then deleting these 4 files:
AutoCAD.py
AutoCAD.pyc
_4E3F492A_FB57_4439_9BF0_1567ED84A3A9_0_1_0.py
_4E3F492A_FB57_4439_9BF0_1567ED84A3A9_0_1_0.pyc
You can notice that the last 2 files are named by the same equivalent generated symbol which is mentioned in the file AutoCAD.py .
I'm new to Python. This is my first Ansible module in order to delete the SimpleDB domain from ChaosMonkey deletion.
When tested in my local venv with my Mac OS X, it keeps saying
Module unable to decode valid JSON on stdin. Unable to figure out
what parameters were passed.
Here is the code:
#!/usr/bin/python
# Delete SimpleDB Domain
from ansible.module_utils.basic import *
import boto3
def delete_sdb_domain():
fields = dict(
sdb_domain_name=dict(required=True, type='str')
)
module = AnsibleModule(argument_spec=fields)
client = boto3.client('sdb')
response = client.delete_domain(DomainName='module.params['sdb_domain_name']')
module.exit_json(changed = False, meta = response)
def main():
delete_sdb_domain()
if __name__ == '__main__':
main()
And I'm trying to pass in parameters from this file: /tmp/args.json.
and run the following command to make the local test:
$ python ./delete_sdb_domain.py /tmp/args.json
please note I'm using venv test environment on my Mac.
If you find any syntax error in my module, please also point it out.
This is not how you should test your modules.
AnsibleModule expects to have specific JSON as stdin data.
So the closest thing you can try is:
python ./delete_sdb_domain.py < /tmp/args.json
But I bet you have your json file in wrong format (no ANSIBLE_MODULE_ARGS, etc.).
To debug your modules you can use test-module script from Ansible hacking pack:
./hacking/test-module -m delete_sdb_domain.py -a "sdb_domain_name=zzz"
My traceback from running pandas takes me to:
site-packages\pandas\io\excel.py line 58, in get_writer
AttributeError: 'module' object has no attribute '__version__'
I found this link to a git issue in the PyInstaller repo
https://github.com/pyinstaller/pyinstaller/issues/1890 and found my openpyxl version, manually added it into the get_writer method like so:
def get_writer(engine_name):
if engine_name == 'openpyxl':
try:
import openpyxl
#remove when conda update available
openpyxl.__version__ = '2.3.2'
# with version-less openpyxl engine
# make sure we make the intelligent choice for the user
if LooseVersion(openpyxl.__version__) < '2.0.0':
return _writers['openpyxl1']
elif LooseVersion(openpyxl.__version__) < '2.2.0':
return _writers['openpyxl20']
else:
return _writers['openpyxl22']
except ImportError:
# fall through to normal exception handling below
pass
try:
return _writers[engine_name]
except KeyError:
raise ValueError("No Excel writer '%s'" % engine_name)
Still no dice. The line number given in the error traceback doesn't even change. I then updated the openpyxl version to 2.3.5, still receiving the error. The openpyxl init file has a version variable in it:
try:
here = os.path.abspath(os.path.dirname(__file__))
src_file = os.path.join(here, ".constants.json")
with open(src_file) as src:
constants = json.load(src)
__author__ = constants['__author__']
__author_email__ = constants["__author_email__"]
__license__ = constants["__license__"]
__maintainer_email__ = constants["__maintainer_email__"]
__url__ = constants["__url__"]
__version__ = constants["__version__"]
except IOError:
# packaged
pass
Any known or potential fixes or workarounds?
Edits were not making an impact because the process was compiled into an exe that these modules were running through. Exported the sections I needed outside of my anaconda environment and now the process works without a hitch.
I will add my workaround to this discussion as I was having the same problem using openpyxl 2.4.0 and maybe a few others are stuck too.
I found that to create a .exe file you have to revert to an older version of openpyxl. To do so:
Open the command prompt and uninstall openpyxl with 'pip uninstall openpyxl'
Reinstall openpyxl using an older version 'pip install openpyxl==2.3.5'
Now you should be able to create your .exe file using py2exe, cx_freeze, etc.
This is my fix: go to your openpyxl site-package folder (for me it's: C:\Python27\Lib\site-packages\openpyxl). Copy all variables in your .constant.json file directly into the _ init _.py file, so it looks like:
import json
import os
__author__= "See AUTHORS"
__author_email__= "eric.gazoni#gmail.com"
__license__= "MIT/Expat",
__maintainer_email__= "openpyxl-users#googlegroups.com"
__url__= "http://openpyxl.readthedocs.org"
__version__= "2.4.0"
try:
here = os.path.abspath(os.path.dirname(__file__))
I have just installed ocropus OCR with all dependencies in my windows 7 machine. (I am using 32bit python 2.7) It seems to be working fine except that I cannot load the default OCR model: en-default.pyrnn.gz. , and receiving a Traceback. I am using the following syntax:
python ocropus-rpred -m en-default.pyrnn.gz book\0001\*.png
here is the error
INFO: #inputs47

I have checked the file is not empty; also double checked the binary mode flag enabled i.e. "wb" and "rb"; also converted the newlines of common.py using dos2unix. I am being unable to unable to solve this problem. If anyone have expereinced similar issues, kindly share.

UPDATE: Hi, please note that I have used Python's native gzip, and it is working fine. Thank you for pointing that out. Here is the correct syntax that is working on Windows: {with gzip.GzipFile(fname,"rb") as stream:}
Your use of gunzip (in the load_object function) is incorrect. Unless passed the -c argument, gunzip writes the decompressed data to a new file, not to its stdout (which is what you seem to be attempting to do).
As a result, it doesn't write anything to its stdout, and your stream variable contains no data, hence the EOFError.
A quick fix is to change your gunzip command line to give it the -c argument.
More info here: http://linux.die.net/man/1/gzip
That said, why are you even shelling out to gunzip to decompress your data? Python's built-in gzip module should handle that without problems.
I've looked all around Google and its archives. There are several good articles, but none seem to help me out. So I thought I'd come here for a more specific answer.
The Objective: I want to run this code on a website to get all the picture files at once. It'll save a lot of pointing and clicking.
I've got Python 2.3.5 on a Windows 7 x64 machine. It's installed in C:\Python23.
How do I get this script to "go", so to speak?
=====================================
WOW. 35k views. Seeing as how this is top result on Google, here's a useful link I found over the years:
http://learnpythonthehardway.org/book/ex1.html
For setup, see exercise 0.
=====================================
FYI: I've got zero experience with Python. Any advice would be appreciated.
As requested, here's the code I'm using:
"""
dumpimages.py
Downloads all the images on the supplied URL, and saves them to the
specified output file ("/test/" by default)
Usage:
python dumpimages.py http://example.com/ [output]
"""
from BeautifulSoup import BeautifulSoup as bs
import urlparse
from urllib2 import urlopen
from urllib import urlretrieve
import os
import sys
def main(url, out_folder="C:\asdf\"):
"""Downloads all the images at 'url' to /test/"""
soup = bs(urlopen(url))
parsed = list(urlparse.urlparse(url))
for image in soup.findAll("img"):
print "Image: %(src)s" % image
filename = image["src"].split("/")[-1]
parsed[2] = image["src"]
outpath = os.path.join(out_folder, filename)
if image["src"].lower().startswith("http"):
urlretrieve(image["src"], outpath)
else:
urlretrieve(urlparse.urlunparse(parsed), outpath)
def _usage():
print "usage: python dumpimages.py http://example.com [outpath]"
if __name__ == "__main__":
url = sys.argv[-1]
out_folder = "/test/"
if not url.lower().startswith("http"):
out_folder = sys.argv[-1]
url = sys.argv[-2]
if not url.lower().startswith("http"):

sys.exit(-1)
main(url, out_folder)
On windows platform, you have 2 choices:
In a command line terminal, type
c:\python23\python xxxx.py
Open the python editor IDLE from the menu, and open xxxx.py, then press F5 to run it.
For your posted code, the error is at this line:
def main(url, out_folder="C:\asdf\"):
It should be:
def main(url, out_folder="C:\\asdf\\"):
Usually you can double click the .py file in Windows explorer to run it. If this doesn't work, you can create a batch file in the same directory with the following contents:
C:\python23\python YOURSCRIPTNAME.py
Then double click that batch file. Or, you can simply run that line in the command prompt while your working directory is the location of your script.
Since you seem to be on windows you can do this so python <filename.py>. Check that python's bin folder is in your PATH, or you can do c:\python23\bin\python <filename.py>. Python is an interpretive language and so you need the interpretor to run your file, much like you need java runtime to run a jar file.
use IDLE Editor {You may already have it} it has interactive shell for python and it will show you execution and result.
Your command should include the url parameter as stated in the script usage comments.
The main function has 2 parameters, url and out (which is set to a default value)
C:\python23\python "C:\PathToYourScript\SCRIPT.py" http://yoururl.com "C:\OptionalOutput\"
If you want to run .py files in Windows, Try installing Git bash
Then download python(Required Version) from python.org and install in the main c drive folder
For me, its :
"C:\Python38"
then open Git Bash and go to the respective folder where your .py file is stored :
For me, its :
File Location : "Downloads"
File Name : Train.py
So i changed my Current working Directory From "C:/User/(username)/" to "C:/User/(username)/Downloads"
then i will run the below command
" /c/Python38/python Train.py "
and it will run successfully.
But if it give the below error :
from sklearn.model_selection import train_test_split
ModuleNotFoundError: No module named 'sklearn'
Then Do not panic :
and use this command :
" /c/Python38/Scripts/pip install sklearn "
and after it has installed sklearn go back and run the previous command :
" /c/Python38/python Train.py "
and it will run successfully.
