While installing deepstream 7.0 and running deepstream-test1, I got a No module named ‘cuda’ error.

$ sudo python3 deepstream_test_1.py /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264

Traceback (most recent call last):
  File "/opt/nvidia/deepstream/deepstream-7.0/sources/deepstream_python_apps/apps/deepstream-test1/deepstream_test_1.py", line 26, in <module>
	from common.platform_info import PlatformInfo
  File "/opt/nvidia/deepstream/deepstream-7.0/sources/deepstream_python_apps/apps/deepstream-test1/../common/platform_info.py", line 21, in <module>
	from cuda import cudart
ModuleNotFoundError: No module named 'cuda'

I also did

pip3 install cuda-python

but when I run test I get the same error.

How can I fix the error and run test 1?

Is there any difference in the output of the following two commands?

python -c "import sys; print(sys.executable)"

sudo python -c "import sys; print(sys.executable)"

Or you can try sudo pip install cuda-python

Or

sudo chmod -R a+w /opt/nvidia/deepstream/deepstream

python3 deepstream_test_1.py /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264

I ran the following code and successfully ran test 1.

sudo pip install cuda-python

But when I run test 1,

$ sudo python3 deepstream_test_1.py /opt/nvidia/deepstream/deepstream/samples/streams/sample_720p.h264

GStreamer-WARNING occurs and test 1 runs successfully.

GStream-WARNING did not occur with deepstream 6.4, but this can be safely ignored.

Since some components are not supported by the system, these warnings are normal

For this, it’s a issue about glib， please refer this link

Now runs well. thank you.
