finn-examples not installable on Pynq-Z1 board #2

Closed chhait07 closed 3 years ago

chhait07 commented 3 years ago

Hi everybody! I wanted to test some finn-examples from https://github.com/Xilinx/finn-examples on my Pynq-Z1-Board. I followed the instructions in section Quickstart.

  1. Instruction python3 -m pip install --upgrade pip setuptools worked successfully.
  2. The next instruction pip3 install finn-examples shows some errors, see the following screenshot.

Install_finn-examples

Can you help me here?

Hi @chhait07 -- can you try this with root privileges? Either sudo pip3 install ... or running su first prior to running pip3 install.

I've also moved this issue to finn-examples as this issue relates to that repo.

chhait07 commented 3 years ago

Hi @maltanar , I tested the command in both ways: sudo pip3 install finn-examples and su followed by pip3 install finn-examples. The output in both cases is the same as in my first comment.

Do you have any other ideas?

maltanar commented 3 years ago

The core error in the screenshot from your first message seems to be OSError: Root permissions required which sudo really should resolve. If it doesn't there might be something wrong with your PYNQ installation -- make sure you are using the latest PYNQ image. If the problem persists I'd ask for help on the PYNQ forum: https://discuss.pynq.io/

Hi @maltanar, yes you are right, the output is different when executing the command with sudo. I'm sorry I've overlooked that. Here is the screenshot when trying with sudo: Issue_Install_sudo

Which PYNQ version are you using? If not the latest (v2.6.1) can you upgrade to the latest PYNQ version and try again?

chhait07 commented 3 years ago

Hi @maltanar. On my board PYNQ version 2.4 was running. I now updated it to version 2.6.0. I tried to update to 2.6.1 but that didn't work. I think due to this article version 2.6.0 should be sufficient. If not, can you tell me how to update to V2.6.1?

I again tried to install finn-examples with the following result: Install_error_updated

There seems to be missing a package or directory. What can I do to solve the problem?

Does sudo python3 -m pip install --upgrade pip setuptools help?

chhait07 commented 3 years ago

Hi @maltanar , I tried sudo python3 -m pip install --upgrade pip setuptools but this exited with an error. When I omit the sudo I can successfully upgrade pip setuptools. See screenshot: Bildschirmfoto von 2021-03-05 06-23-12

I then tried to install finn-examples again, with the same output as in my last comment: Bildschirmfoto von 2021-03-05 06-32-14

It looks like you are having connection issues while upgrading setuptools above (Temporary failure in name resolution). Try again with sudo on both commands. If the problem persists I'd ask for help on the PYNQ forum: https://discuss.pynq.io/

Hi @maltanar , today I tried again installing the setuptools with sudo python3 -m pip install --upgrade pip setuptools . This time it was successfully installed without errors (I have no idea why it is successful this time). My board is now updated from setuptools 39.0.1 to 54.1.1 Now I can successfully install finn-examples! Thank you @maltanar for your help!

Unfortunately I have now another problem on retrieving the example Jupyter notebooks. Thus I opened a new issue and I will close this issue.
