When using win32com, something puzzled my.
>>> import win32com
>>> w=win32com.client.Dispatch('Word.Application')
Traceback (most recent call last):
File "<pyshell#1>", line 1, in <module>
w=win32com.client.Dispatch('Word.Application')
AttributeError: 'module' object has no attribute 'client'
what's wrong?
win32com.client is a module in the win32com package you need to import the actual module.
import win32com.client
w = win32com.client.Dispatch('Word.Application')

I run my scrapy as a standalone script like this
if __name__ == "__main__":
from scrapy.crawler import CrawlerProcess
from scrapy.utils.project import get_project_settings
s = get_project_settings()
process = CrawlerProcess(s)
process.crawl(MySpider)
process.start()
my scraper was consuming huge memory so i thought of using these two custom settings.
SCHEDULER_DISK_QUEUE = "scrapy.squeue.PickleFifoDiskQueue"
SCHEDULER_MEMORY_QUEUE = "scrapy.squeue.FifoMemoryQueue"
But after adding these two custom settings and when i run my standalone spider I get error saying.
Traceback (most recent call last):
File "/usr/local/lib/python3.9/dist-packages/twisted/internet/defer.py", line 1696, in _inlineCallbacks
result = context.run(gen.send, result)
File "/usr/local/lib/python3.9/dist-packages/scrapy/crawler.py", line 118, in crawl
yield self.engine.open_spider(self.spider, start_requests)
ModuleNotFoundError: No module named 'scrapy.squeue'
Any ideas what's the issue with this ?
ModuleNotFoundError: No module named 'scrapy.squeue'
You have a typo:
SCHEDULER_DISK_QUEUE = "scrapy.squeues.PickleFifoDiskQueue"
SCHEDULER_MEMORY_QUEUE = "scrapy.squeues.FifoMemoryQueue"
I installed GIS-Pro and use Jupyter. I believe Jupyter is in the GIS-Pro package. I use Jupyter to write Python codes. Since yesterday, I've got the following errors once executing import pandas as pd :

I have a python package called CoreCode which I have compiled using clr.CompileModules() in IronPython 2.7.5. This generated a file called CoreCode.dll. I then import this dll into my IronPython module by using clr.AddReference(). I know the dll works because I have successfully tested some of the classes as shown below. However, my problem lies with the Base_Slice_Previewer class. This class makes use of Image and ImageDraw from PIL in order to generate and save a bitmap file.
I know the problem doesn't lie with PIL because the package works perfectly well when run in Python 2.7. I'm assuming that this error is coming up because IronPython can't find PIL but I'm not sure how to work around this problem. Any help will be much appreciated.
Code to create the dll
import clr
clr.CompileModules("CoreCode.dll", "CoreCode\AdvancedFileHandlers\ScannerSliceWriter.py", "CoreCode\AdvancedFileHandlers\__init__.py", "CoreCode\MarcamFileHandlers\MTTExport.py", "CoreCode\MarcamFileHandlers\MTTImporter.py", "CoreCode\MarcamFileHandlers\__init__.py", "CoreCode\Visualizer\SlicePreviewMaker.py", "CoreCode\Visualizer\__init__.py", "CoreCode\Timer.py", "CoreCode\__init__.py")
Test for Timer.py
>>> import clr
>>> clr.AddReference('CoreCode.dll')
>>> from CoreCode.Timer import StopWatch
>>> stop_watch = StopWatch()
>>> print stop_watch.__str__()
0:00:00:00 0:00:00:00

Test for MTTExport.py

>>> in_val = (2**20)+ (2**16) + 2
>>> bytes = mttlayer.write_lf_int(in_val, force_full_size=True)

I have an small code that uses pandas and sqlalchemy and is declared in my main.py as:
import pandas as pd
from sqlalchemy import create_engine
this is my complete setup.py:
from distutils.core import setup
import py2exe
from glob import glob
data_files = [("Microsoft.VC90.CRT", glob(r'C:\Users\Flavio\Documents\Python_dll\*.*'))]
opts = {
"py2exe": {
"packages": ["pandas", "sqlalchemy"]
}
}
setup(
data_files=data_files,
options = opts,
console=['main.py']
)
And I'm using this command in terminal:
python setup.py py2exe
But when I run main.exe it's open the terminal start to execute code and suddenly close window.
when I run over terminal it's the error:
C:\Users\Flavio\Documents\python\python\untitled\dist>main.exe
Please add a valid tradefile date as yyyymmdd: 20150914

without know what your program does
I would try the following 1st
open a command window and run your .exe from there
The window will not close and any error messages (if any) will be displayed

Python by default doesn't include submodules into packages' namespace - it must be done by hand by programmer. Some packages are written to do it - for example package 'os' puts 'path' in own namespace so 'import os' is enough to use both 'os' and 'os.path' functions - but in general all module imports need to be explicit.
