I'm using eclipse with PyDev, Python 2.7, and have the following problem.
From a package, containing .py and c modules, i have imported the .py modules, but not the C source files.
I have imported the C Function module (.py!) from the sg package, which includes the following line:
try:
import sg._cfunc as _cfunc
except ImportError:
import pyximport
pyximport.install(setup_args={"include_dirs": np.get_include()},
reload_support=True)
import sg._cfunc as _cfunc
ImportError: No module named _cfunc
However the C Source file is in .../site-packages/sg.
Moreover, this function was working beforehand, and is still working on an other computer.
I have already reinstalled Cython, but nothing happened.
Any idea? :(

I am stuck on this error from quite sometime. I am trying to read an excel file (.xlsx file) using the xlsx package.
import XLSX from 'xlsx'
This is how I read the excel file
var workbook = XLSX.readFile('./file.xlsx');
This file is in the same folder as the code is in. So the path seems to be right as well.
I do not get any compile time errors, but when I go on the UI and click the download button, the above line is triggered (reading from an excel file), and this is the error that is seen:
Looks like xlsx package is trying to use fs package from #types/node module.
I have also installed #types/node package which is required for fs.
I even tried to check if file sync works and tried reading a file via fs.readFileSyn ... but I keep getting an error during compile time (when I do npm run start), that Module not found: Error: Can't resolve 'fs' in ...
I tried importing fs in these two ways:
import * as fs from 'fs'
import fs from 'fs' I tried with require as well.
but none of those these worked.
note: My webpack file has css loader and a ts loader. I'm not too sure if webpack(loaders) could be the issue. Let me know if this could be the issue and why?
Can someone please help me resolve the above error mentioned? I'm trying to figure this one out from quite sometime.
I am trying to call this C library from my Swift code. I dragged the source files into my project and created a module.map file and added the directory containing the module map to Build Settings->Search Paths->Import Paths.
It seems to work. I can import the library and the name even shows up in autocomplete:
And I can access functions from the library and again autocomplete knows they are there:
But when I build, I get this error:
This name, "_mtex2MML_parse", is the same as the name of C function I'm trying to call except prefixed with an underscore.
I've gotten this same error before in similar circumstances trying to get cmark to work, but fixed it there by making sure that the .c file was included in the Target Membership, and then everything was fine. When I fiddled with doing that in this project, I've not had any luck. And in that case, autocomplete didn't even know about the function.
I've tried cleaning, deleting derived data, quitting Xcode, restarting computer, etc. I've tried on Xcode 8.3.3 Swift 3.1 and on Xcode 9b4, Swift 4.0. I'm on macOS 10.12.6. There is no other thing in the project besides this.
Can anyone offer any advice on how to proceed? Thanks.
I have a submodule in my golang google-app-engine project that I would like to add to my path.
$ ls ./openid/src/openid
discover.go integration verify.go
discover_test.go nonce_store.go xrds.go
discovery_cache.go nonce_store_test.go xrds_test.go
fake_getter_test.go normalizer.go yadis_discovery.go
getter.go normalizer_test.go yadis_discovery_test.go
html_discovery.go redirect.go
html_discovery_test.go redirect_test.go
In the example code for this package, it imports "openid". I'm new to golang's import rules, and I can't for the life of me figure out what I need to put in the import statement of my main file to import this package. I've tried "openid/src/openid", "myapp/openid/src/openid", etc. Can someone provide some clarification of how this works? Or do I need to actually modify the app.yaml file?
"Organizing Go code" mentions:
An import path is the string with which users import a package.
It specifies the directory (relative to $GOROOT/src/pkg or $GOPATH/src) in which the package's source code resides.
So make sure to use an import statement referring to a path which exists in your $GOPATH/src. (GOPATH being your "workspace", in which you have namespaces, as shown in this video).
Also make sure you build first openid/src/openid sources. And install it (go install).
As detailed in this answer:
Import paths can be be globally unique.
In conjunction with GOPATH, import path can be translated unambiguously to a directory path.
Any directory path under GOPATH can be unambiguously translated to an import path.
I'm using PyCharm 2.6.3 and Python 2.7.5 for my Google Application Engine project.
Today occurred strange error when I was trying to debug my GAE project:
ImportError: No module named pydevd_vm_type
Module exists but doesn't want to be imported somewhere in debug tools.
When I trying to type "import pydevd_vm_type", autocomplete tool gives me right path to that module. How can I solve this issue?
Problem solved!
File Path_on_disk\PyCharm 2.6.3\helpers\pydev\pydevd.py
Error occurs in class
class PyDBCommandThread(PyDBDaemonThread)
in method
def OnRun(self)
...
import pydevd_vm_type
if pydevd_vm_type.GetVmType() == pydevd_vm_type.PydevdVmType.JYTHON and sys.hexversion <= 0x020201f0:
# a lot of comments about Jython bug
run_traced = False
and next in
import pydevd_tracing
if run_traced:
pydevd_tracing.SetTrace(None) # no debugging on this thread
I've deleted those two imports. PROFIT!!!
I am still new to Python and GAE. I have an application on local server that is running just fine. I can add entity to my datastore, I can view my website, etc: everything is fine.
Now I am trying to use bulkloader to add entities to my datastore. I followed the tutorial at https://developers.google.com/appengine/docs/python/tools/uploadingdata. My loader is below:
from google.appengine.ext import ndb
from google.appengine.tools import bulkloader
import my_model
class ArticleLoader(bulkloader.Loader):
def __init__(self):
bulkloader.Loader.__init__(self, 'Article',
[('title', str),
('author', str)
])
loaders = [ArticleLoader]
I am getting the error:
No module named my_model
Does anyone have a fix for this?
Note: I am only using one directory. So my loader is in the same location as the other file that imports the my_model module.
This can also happen if your PYTHONPATH is not properly set up. If you're on Linux, try running this before you run the Bulkloader:
export PYTHONPATH=$PYTHONPATH:.
This appends your current directory to your PYTHONPATH and should make your my_model module visible. Since my memory is terrible and I always forget to do it, I've ended up using a simple shell script that includes this at the beginning and then the bulkload command itself.
If you're on Windows, you should be able to modify your path by using sys.path.append. Haven't tested this, but you could try adding this to your script (note that this should work on Linux as well):
import sys
# ...
sys.path.append('.')
Your code should be located in a file named my_model.py. You are getting that error because there is no module named my_module. Might be worth a read of the Python module and package docs.
