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
Traceback (most recent call last):

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

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 've been reading almost all the posts related to this topic but I can´t find a solution!!!.
My folder path is : C:\Users\User\Desktop\Data Analytics Arg\py_inst
Inside the folder I created a virtual env., I added the chromedriver.exe and my script as it can be seen in the image:
this is my script:

Could someone help me please???.
This error message...
UPX is not available
...implies that pyinstaller can not find upx.exe to encrypt exe file.
Solution
In order to fix this error you need to download upx as per your system configuration. Incase of a 64-bit windows OS you need to download:
Incase you have downloaded upx and saved in D:\ you need to do:
pyinstaller main.py --key 123456 -n test -F -w --upx-dir D:\
I developed an ANN tool by using pycharm/tensorflow on my own computer. I uploaded the h5 and json files to Amazon Sagemaker by creating a Notebook Instance. I was finally able to successfully create an endpoint and make it work. The following code in Notebook Instance -Jupyter works:
import json
import boto3
import numpy as np
import io
import sagemaker
from sagemaker.tensorflow.model import TensorFlowModel
client = boto3.client('runtime.sagemaker')
data = np.random.randn(1,6).tolist()
endpoint_name = 'sagemaker-tensorflow-**********'
response = client.invoke_endpoint(EndpointName=endpoint_name, Body=json.dumps(data))
response_body = response['Body']
print(response_body.read())
However, the problem occurs when I created a lambda function and call the endpoint from there. The input should be a row of 6 features -that is a 1-by-6 vector. I enter the following input into lambda {"data":"1,1,1,1,1,1"} and it gives me the following error:
Traceback (most recent call last):
File "/var/task/lambda_function.py", line 20, in lambda_handler
Body=payload)
File "/var/runtime/botocore/client.py", line 316, in _api_call
return self._make_api_call(operation_name, kwargs)
File "/var/runtime/botocore/client.py", line 635, in _make_api_call
raise error_class(parsed_response, operation_name)
I think the problem is that the input needs to be 1-by-6 instead of 6-by-1 and I don't know how to do that.
I assume the content type you specified is text/csv, so try out:
{"data": ["1,1,1,1,1,1"]}
I want to create a command line with python (argparse). The goal is to import a dataframe and then print its 5 first rows, however, when I run the command, this error shows up :
File "try.py", line 3, in <module>
import pandas as pd
File "C:\Users\szouaoui\AppData\Local\Continuum\anaconda3\lib\site-packages\pandas\__init__.py", line 17, in <module>
"Unable to import required dependencies:\n" + "\n".join(missing_dependencies)
ImportError: Unable to import required dependencies:
numpy: DLL load failed: Le module spécifié est introuvable.
it seems that the program is unable to import the pandas library
here is the code:
import argparse
import sys
import pandas as pd
my_parser = argparse.ArgumentParser(description='Unconstraining demand for specified dates, shops and categories/n')
my_parser.add_argument("path",type=str, action="store")
my_args = my_parser.parse_args()
input_file = sys.argv[1]
data = pd.read_csv(input_file)
print(data.head())
command line :
python try.py /path_to_file/dataframe_name.csv
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

>>> clr.AddReference('CoreCode.dll')
>>> from CoreCode.Timer import StopWatch

Test for MTTExport.py
