ModuleNotFoundError: No module named 'common.is_aarch_64'

[user43056]

Please provide complete information as applicable to your setup.

• Hardware Platform (Jetson / GPU): GPU
• DeepStream Version: 6.0
• TensorRT Version: 8.0.1
• NVIDIA GPU Driver Version (valid for GPU only): 495.44

(P.S.: I am using DeepStream in colab, and it working fine)
Recently I git cloned the ‘deepstream_python_apps’ repository from github. I have fulfilled all the prerequisutes: I have Ubuntu 18.04, DeepStream SDK 6.0, Python 3.6 and have installed/git-cloned Gst Python v1.14.5.
When running any of the code given in the apps folder inside the git cloned folder, I am getting an error like:

Traceback (most recent call last):
  File "/opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps/apps/deepstream-test3/deepstream_test_3.py", line 32, in <module>
    from common.is_aarch_64 import is_aarch64
ModuleNotFoundError: No module named 'common'

For that I installed common library:

!pip install common

Then I got an error saying:

Traceback (most recent call last):
  File "/opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps/apps/deepstream-test3/deepstream_test_3.py", line 32, in <module>
    from common.is_aarch_64 import is_aarch64
ModuleNotFoundError: No module named 'common.is_aarch_64'

Later I noticed that there is a common folder inside the apps folder itself, containing an ‘is_aarch_64.py’ file. But inspite of that I am getting an error of no such module. How can I solve it?

Common is one directory under python app directory.
Did you use sys.path.append(‘…/’) or sys.path.append(‘./’)
if the later one, please change to the first one.

[user43056]

Yeah, its is sys.path.append(‘…/’)

But still I am getting this error:

After I pip install the common library, I get this error:

Now what should I do?

[Amycao]

Common is not one library. it’s one directory as said.
Where did you run from?

[user43056]

As mentioned above, I am running it from google colab. It is working fine, when config files are executed.

[Amycao]

I mean you run under which directory.
you should run under python test3 app dir
sources/deepstream_python_apps/apps/deepstream-test3/

[user43056]

Yeah, I am running it from that directory only. You can see the path in the picture above:
/opt/nvidia/deepstream/deepstream-6.0/sources/deepstream_python_apps/…

[Amycao]

You are not. go to that directory and run.

[user43056]

Ok. Running it after changing the directory did provide a solution for the common library thing, but it is now giving another error:

Traceback (most recent call last):
  File "deepstream_test_3.py", line 36, in <module>
    import pyds
ModuleNotFoundError: No module named 'pyds'

From 6.0 version, we open sourced python bindings, user need to compile the binding first.
