I ran Python 1.py I got the following error:

Traceback (most recent call last):
File "1.py", line 5, in 
pid = device.spawn(["com.example.a11x256.frida_test"])
File "/usr/local/lib/python2.7/dist-packages/frida/core.py", line 98, in spawn
return self._impl.spawn(program, argv, envp, env, cwd, stdio, aux_options)
frida.TransportError: the connection is closed

And I have mentioned the result of adb devices in the following:

List of devices attached
emulator-5554 device
192.168.56.101:5555 device

And frida-PS -you is coming in the following

PID Name 
55 adbd
6051 android.process.acore
5968 android.process.media
5877 com.android.browser
5472 com.android.deskclock

The frida works fine but I have some trouble when using automation with Python
and my Python is 2.7 and when I have used python3 with 1.py I got this following error
Traceback (most recent call last):
File "1.py", line 2, in
import frida
ModuleNotFoundError: No module named 'frida'

And my 1.py file is in the following too

#python code
import frida
import time
device = frida.get_usb_device(1)
pid = device.spawn(["com.example.a11x256.frida_test"])
device.resume(pid)
time.sleep(1) #Without it Java.perform silently fails
session = device.attach(pid)
script = session.create_script(open("s1.js").read())
script.load()

#prevent the python script from terminating
raw_input()

Is there any solution?
