代码可在 Anaconda 上运行，但不能通过 cmd 在 Python 上运行

Question

I have code that runs over 7000 columns dataset with around 250k records

it works fine when I use Anaconda Spyder

but now I want to put this code to run based on Task Schedule

Therefore I am want to execute the code in cmd Command Prompt as

Python "c:\myfolder\predservice.py"

It didn't work as Task Schedule

I start tracing the problem by running the script on Python from within cmd

I got this error, which I did not get when I was running through Spyder

How can I avoid such error

I thought it is because of the memory. when i select a subset of the dataset it runs fine but when I run the whole dataset i get this error

>>> df =pd.concat([df.drop('PreviousDRGs', 1), pd.get_dummies(df['PreviousDRGs'] .str.split(",", expand=True), prefix
 = 'PreviousDRGs').max(level=0, axis=1).asty pe(np.int8)], axis=1)

Answer 1

Looks like Anaconda may be using a 64-bit python. Your error traceback shows that your Task Scheduler is running your .py script using a 32-bit python. Either

1. replace your 32-bit python with a 64-bit version
2. or install a separate 64-bit python and tell Task Scheduler to use that to run your .py file.

Answer 2

I think you need to activate your conda base in cmd before calling the script

call <path>\anaconda\Scripts\activate base
<path>\anaconda\python.exe <path>\scriptname.py
