I get this traceback when attempting to connect to a serial port on ubuntu 16.04

File "debugRead2.py", line 6, in <module>
ser = serial.Serial('/dev/ttyACM0', 115200)
AttributeError: module 'serial' has no attribute 'Serial'

My file is named debugRead2.py so it isn't an issue with naming.

When I change:

import serial
ser = serial.Serial('/dev/ttyACM0', 115200)

from serial import serial
ser = serial.Serial('/dev/ttyACM0', 115200)

I get:

Traceback (most recent call last):
  File "debugRead2.py", line 1, in <module>
    from serial import serial
ImportError: cannot import name 'serial'

I have both the serial and pyserial packages installed.

did you install using `pip` ? – scharette Nov 20 '17 at 03:31
yes i used pip to install – Cole Havener Nov 20 '17 at 03:32
Try uninstalling the `serial` package. That one is for serializing JSON/YAML/XML, not using serial ports. It might be causing a conflict. – Aneel Nov 20 '17 at 03:33

Open the Python interpreter from the same folder your code is in and type `import serial; serial`! What's the output? – Klaus D. Nov 20 '17 at 03:34
just did, am still getting the same error – Cole Havener Nov 20 '17 at 03:35
You probably need to change it to `from serial import Serial; ser = Serial('/dev/ttyACM0', 115200)` – Sudheesh Singanamalla Nov 20 '17 at 03:39
when i type 'import serial;' serial I get '' – Cole Havener Nov 20 '17 at 03:39
When I change it to `from serial import Serial; ser = Serial('/dev/ttyACM0', 115200)` I get `ImportError: cannot import name 'Serial'` @SudheeshSinganamalla – Cole Havener Nov 20 '17 at 03:48
That should usually print the filename of the module. Try `import serial; print(serial.__file__)` instead. – Klaus D. Nov 20 '17 at 03:48
`>>> import serial; print(serial.Serial) Traceback (most recent call last): File "", line 1, in AttributeError: module 'serial' has no attribute 'Serial'` @KlausD. – Cole Havener Nov 20 '17 at 03:50
That's not the command I gave you. – Klaus D. Nov 20 '17 at 03:52
I am wondering if you installed the right `serial` library. Did you install `serial` or `pyserial` ? This issue occurs because the right library you're looking for is `pyserial` – Sudheesh Singanamalla Nov 20 '17 at 03:52
I installed both the serial and pyserial library, but uninstalled the serial library @SudheeshSinganamalla – Cole Havener Nov 20 '17 at 03:54
`import serial; print(serial.__file__) Traceback (most recent call last): File "", line 1, in AttributeError: module 'serial' has no attribute '__file__'` @KlausD. – Cole Havener Nov 20 '17 at 03:55
This question should never have been closed as a duplicate of the other, because the cause is fundamentally different. Instead, the answers about installing `pyserial` rather than `serial` should have gone here. – Karl Knechtel Aug 01 '22 at 07:00
