AttributeError module 'serial' has no attribute 'Serial'

AttributeError module 'serial' has no attribute 'Serial' The Python "AttributeError module 'serial' has no attribute 'Serial'" occurs when we have a local file named serial.py and import from the pyserial module.

To solve the error, make sure you haven't got a file named serial.py, uninstall the serial module and install pyserial.

# Installing the correct module First, make sure you haven't installed the serial module instead of pyserial.

shell

👇️ uninstall serial and pyserial

pip uninstall serial pip uninstall pyserial

pip3 uninstall serial pip3 uninstall pyserial

👇️ install pyserial

pip install pyserial pip3 install pyserial

Now try importing the serial module.

main.py import serial

ser = serial.Serial('/dev/ttyUSB0')

print(ser.name)

Make sure you don't have a file named serial.py Make sure you don't have a local file named serial.py.

If you have a local module that is named serial.py, it would shadow the third-party pyserial module.

Here is an example of how the error occurs in a local file named serial.py.

serial.py import serial

ser = serial.Serial('/dev/ttyUSB0')

⛔️ AttributeError: partially initialized module 'serial' has no

attribute 'Serial' (most likely due to a circular import). Did you mean: 'serial'?

print(ser.name)

The Python interpreter first looks for the imported module in the built-in modules, then in the current directory, then in the PYTHON PATH, then in the installation-dependent default directory.

So, when we create a local file with the same name as that of a third-party module, we effectively shadow the official module with our local file.

It doesn't have to be the file you are running directly. If you have a serial.py file anywhere in the directory, it would shadow the official module.

You can access the file property on the imported module to see whether it is shadowed by a local file.

If your serial import is shadowed by a local file, the result will look something similar to the following.

main.py import serial

print(serial.file)

⛔️ result if shadowed by local file

If your serial import is not shadowed by a local file or variable, the result will look similar to the following.

main.py import serial

print(serial.file)

✅ result if pulling in the correct module
