I am trying to implement FastRCNN using Mindspore, I am using the code from the offciel gitee as a reference:

https://gitee.com/mindspore/mindspore/tree/r1.3

I am using Mindspore 1.3 and VOC dataset. 

I am also using Windows 10


how I can solve the error message: "

    signal.signal(signal.SIGCHLD, wait_child_processes)
AttributeError: module 'signal' has no attribute 'SIGCHLD' "

that appears when I run train.py 


I attached thw full erro traceback as document file with the post


Thank you in advance!

Hello, friend!

AttributeError: Python signal: Module 'signal' has no attribute 'SIGALRM' ", this is because the Signal module can be used normally under Linux but has some limitations under Windows, In the python documentation https://docs.python.org/2/library/signal.html#signal.signal found explained as follows:

"On Windows, signal() can only be called with SIGABRT, SIGFPE, SIGILL, SIGINT, SIGSEGV, or SIGTERM. A ValueError will be raised in any other case."
This means that under Windows, only these signals can be used:
SIGABRT
SIGFPE
SIGILL
SIGINT
SIGSEGV
SIGTERM
Have a nice day!
