dabraude opened a new issue #13875: importing mxnet causing subprocess to crash
URL: https://github.com/apache/incubator-mxnet/issues/13875
 
 
   may be related to #13831
   
   ## Description
   importing mxnet causes OSErrors in subprocess
   
   
   ## Environment info (Required)
   Scientific Linux 7.5
   Python 3.6.3 
   MXnet 1.5.0 (from packages)
   (tried on multiple computers running different cuda builds) 
   
   
   ## Error Message:
   (Paste the complete error message, including stack trace.)
   
   ## Minimum reproducible example
   Using the following script (or just using the appropriate commands)
   
   import mxnet
   import subprocess
   n = 0
   while True:
       if not n%1000: print ("RUN", n)
       ret = subprocess.call(['ls', '/tmp'], stdout=subprocess.PIPE)
       n += 1
   
   will eventually give this error message:
   
   Traceback (most recent call last):
      File "subcrash.py", line 13, in <module>
        ret = subprocess.call(['ls', '/'], stdout=subprocess.PIPE)
      File "/opt/rh/rh-python36/root/usr/lib64/python3.6/subprocess.py", 
   line 267, in call
        with Popen(*popenargs, **kwargs) as p:
      File "/opt/rh/rh-python36/root/usr/lib64/python3.6/subprocess.py", 
   line 709, in __init__
        restore_signals, start_new_session)
      File "/opt/rh/rh-python36/root/usr/lib64/python3.6/subprocess.py", 
   line 1344, in _execute_child
        raise child_exception_type(errno_num, err_msg, err_filename)
   OSError: [Errno 14] Bad address: 'ls'
   
   Doesn't seem to matter which executable.
   
   ## What have you tried to solve it?
   
   Don't even know where to start.
   If you try putting in a stack tract or pdb it won't break.
