I import vtt_to_srt converter.I read the instructions.I make the installation.From beginning to this "no problem" but when I import it as manuals describe python can't find the module there.
Installation
pip install vtt_to_srt3
Usage
from vtt_to_srt import vtt_to_srt
path = '/path/to/file.vtt'
vtt_to_srt(path)
Error
ImportError: cannot import name 'vtt_to_srt' from 'vtt_to_srt'
I am a rookie.Sorry for asking this question.
#SakuraFreak's answer was my immediate thought, too, but I ended up investigating this a bit further. It seems like vtt_to_srt stores all its API in the __main__.py file of the module. This file should normally be used when you want to a module using python -m.
This actually makes the module impossible to use the way that the documentation specifies. What I tried, then was:
from vtt_to_srt.__main__ import vtt_to_srt
print(vtt_to_srt)
This results in:
<function vtt_to_srt at 0x000002A0948216A8>
So it seems like this workaround is OK.
I do not know if storing all the module's code in __main__.py is some convention not supported by my version of Python (CPython 3.7.3 on Windows), or if it simply an error. Maybe you should approach the module's owners with this.
Because you're trying to import a function from the module which doesn't exist.
the correct way for this module is:
import vtt_to_srt

After installing Xadmin, I encounter some problems. These are my error details:
[File "C:\Users\Harry\PycharmProjects\mxonline\lib\site-packages\xadmin\sites.py", line 9, in <module>
reload(sys)
NameError: name 'reload' is not defined][1]
I've tried to import importlib importlib.reload(sys) but it still doesn't work. I am using python 3.6.4.
Assuming that I understand the problem, you are having issues with importing reload from the package importlib and you encounter the NameError when trying to use reload.
If this is all correct, then make sure you are importing reload correctly. If you just want reload try:
from importlib import reload
This will import reload while making it available under the name reload. If you want to give it an alias you could do:
from importlib import reload as foo
Finally, if you needed all of importlib you could also import the package as an alias:
import importlib as il
And then use reload from this like so:
il.reload(sys)
This code is doing something super duper weird and incompatible with Python 3. Importing reload from importlib will not help, even if you were to edit the library's code to import reload, because it is also relying on sys.setdefaultencoding, which does not exist on Python 3.
To use this code on Python 3, you would have to install an updated version directly from github, since the most recent release doesn't have the fix. I don't know whether the code has other issues with Python 3, though. Personally, I would probably not use xadmin at all.
I am trying to package my program using pyinstaller. The code runs fine on windows, and uses SqlAlchemy, OpenCV and pyodbc packages.
I ran pyinstaller to create the executable and tried to run it. I'm getting an error:
ImportError: No module named ConfigParser
now, I reran the same thing and looked at logs from pyinstaller and got a warning:
WARNING: Hidden import "sqlalchemy.sql.functions.func" not found!
along with a few others.
then there was a warning about trying to import ConfigParser in lower and uppercase.
Attempted to add Python module twice with different upper/lowercases: ConfigParser
What might be the issue here?
So, I figured it out. To an extent.
Seems like pyInstaller doesn't deal with SWIG files that well.
In sqlalchemy.utils there's a file called compat.py. It is there to make the module compatible with all versions of python.
for example, in python2.x, there's ConfigParser whereas in py3, it is named configparser
So there is a part in compat.py to deal with it:
if py3:
import configparser
# Some other such import statements
elif py2:
import ConfigParser as configparser
Now, pyinstaller gets stumped here as it just focuses on the import, and hence it tries to import both and fails miserably.
My crude workaround to this involved modifying the compat.py file and retaining only the parts relevant to the python version I have (2.x).
Running pyinstaller again proved to be a success! :)
Although this is all very crude and there's probably something better out there, but I couldn't find anything, so I'm sharing what worked for me.
I have built a .pyd module from some fortran code via f2py, which we can call foo.pyd. I want to import this into a python code, which we can call main.py. When I import as:
import foo
everything works fine. However, because this python will eventually be 'frozen' into an executable, and I will have to package the foo.pyd along with the main.exe, I need to specify an explicit path to import from.
Thus, I tried using the imp module, specifically imp.load_compiled(). When I try:
import imp
foo = imp.load_compiled('foo','foo.pyd')
or even:
foo = imp.load_compiled('foo','./foo.pyd')
I get the following error:
ImportError: Bad magic number in foo.pyd
It seems that this error comes from trying to build in one Python dist, and import in another. However, I'm using the same Python for both, and it works with the standard import command!
Has anyone out there experienced this, and/or possibly have some guidance? I greatly appreciate any help or advice you may have.
imp.load_compiled() is for .pyc files. You're looking for imp.load_dynamic(). Alternatively, you can add the directory you want in sys.path, after which regular imports will work.
I'm self-taught in the Python world, so some of the structural conventions are still a little hazy to me. However, I've been getting very close to what I want to accomplish, but just ran into a larger problem.
Basically, I have a directory structure like this, which will sit outside of the normal python installation (this is to be distributed to people who should not have to know what a python installation is, but will have the one that comes standard with ArcGIS):
top_directory/
ArcToolbox.tbx
scripts/
ArcGIStool.py (script for the tool in the .tbx)
pythonmod/
__init__.py
general.py
xlrd/ (copied from my own python installation)
xlwt/ (copied from my own python installation)
xlutils/ (copied from my own python installation)
So, I like this directory structure, because all of the ArcGIStool.py scripts call functions within the pythonmod package (like those within general.py), and all of the general.py functions can call xlrd and xlwt functions with simple "import xlrd" statements. This means that if the user desired, he/she could just move the pythonmod folder to the python site-packages folder, and everything would run fine, even if xlrd/xlwt/xlutils are already installed.
THE PROBLEM:
Everything is great, until I try to use xlutils in general.py. Specifically, I need to "from xlutils.copy import copy". However, this sets off a cascade of import errors. One is that xlutils/copy.py uses "from xlutils.filter import process,XLRDReader,XLWTWriter". I solved this by modifying xlutils/copy.py like this:
try:
from xlutils.filter import process,XLRDReader,XLWTWriter
except ImportError:
from filter import process,XLRDReader,XLWTWriter
I thought this would work fine for other situations, but there are modules in the xlutils package that need to import xlrd. I tried following this advice, but when I use
try:
import xlrd
except ImportError:
import os, sys, imp
path = os.path.dirname(os.path.dirname(sys.argv[0]))
xlrd = imp.load_source("pythonmod.xlrd",os.path.join(path,"xlrd","__init__.py"))
I get a new import error: In xlrd/init.py, the info module is called (from xlrd/info.py), BUT when I use the above code, I get an error saying that the name "info" is not defined.
This leads me to believe that I don't really know what is going on, because I thought that when the init.py file was imported it would run just like normal and look within its containing folder for info.py. This does not seem to be the case, unfortunately.
Thanks for your interest, and any help would be greatly appreciated.
p.s. I don't want to have to modify the path variables, as I have no idea who will be using this toolset, and permissions are likely to be an issue, etc.
I realized I was using imp.load_source incorrectly. The correct syntax for what I wanted to do should have been:
imp.load_source("xlrd",os.path.join(path,"xlrd","__init__.py"))
In the end though, I ended up rewriting my code to not need xlutils at all, because I continued to have import errors that were causing many more problems than were worth dealing with.
The following is my code.
import http
h1 = http.client.HTTPConnection('www.bing.com')
I think it's ok.But python give me the following error:
AttributeError: 'module' object has no attribute 'client'.
I wanted to know why and how to fix it.Thanks.
First, importing a package doesn't automatically import all of its submodules.*
So try this:
import http.client
If that doesn't work, then most likely you've got a file named http.py, or a directory named http, somewhere else on your sys.path (most likely the current directory). You can check that pretty easily:
import http
http.__file__
That should give some directory like /usr/lib/python3.3/http/__init__.py or /Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/http/__init__.py or something else that looks obviously system-y and stdlib-y; if you instead get /home/me/src/myproject/http.py, this is your problem. Fix it by renaming your module so it doesn't have the same name as a stdlib module you want to use.
If that's not the problem, then you may have a broken Python installation, or two Python installations that are confusing each other. The most common cause of this is that installing your second Python edited your PYTHONPATH environment variable, but your first Python is still the one that gets run when you just type python.
* But sometimes it does. It depends on the module. And sometimes you can't tell whether something is a package with non-module members (like http), or a module with submodules (os). Fortunately, it doesn't matter; it's always save to import os.path or import http.client, whether it's necessary or not.
