How to fix "ImportError: cannot import name 'dataclass'"?

[htliu6]

Excuse me, I encountered following issues when setting up edge node. Have you ever notice this problem? Thanks!

$ python3 edge_main.py -f ~/cutout1.mp4 -i 50

I'm sorry that I have never met the issue you have encountered. From the error content, I think the pytorch version causes the problem. Have you correctly installed the pytorch package? &nbsp; &nbsp; ------------------&nbsp;Original&nbsp;------------------ From: ***@***.***&gt;; Date: &nbsp;Tue, Apr 26, 2022 02:51 PM To: ***@***.***&gt;; Cc: ***@***.***&gt;; Subject: &nbsp;[MSNLAB/SmartEye] How to fix "ImportError: cannot import name 'dataclass'"?

Thanks for your kindly reply! I install pytorch using the following command line
pip install torch==1.8.0+cpu torchvision==0.9.0+cpu torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html
from https://pytorch.org/get-started/previous-versions/#linux-and-windows-11, and everything gets OK when installation finished.

I wonder whether this matters if I have no GPU with my VM.

Using GPU or no GPU is alright. Our framework support both.

Thanks for your reply! BTW, I wonder which version of opencv-python you adopted when running this repo. Thanks!

I used an arm achitecture computer, so the version is 3.2.0+dfsg-4build2 arm64.&nbsp; I do not know if this can help you. &nbsp; &nbsp; ------------------&nbsp;Original&nbsp;------------------ From: "htliu6"; Date: 2022年4月27日(星期三) 下午4:57 To: "MSNLAB/SmartEye"; Cc: ***@***.***>; "Comment"; Subject: Re: [MSNLAB/SmartEye] How to fix &quot;ImportError: cannot import name 'dataclass'&quot;?
