Installation issue on x64

[bpinaya]

Hi there, I've followed your building guide, and while installing the wheels built from source I had the following error.

The directory '/home/bpinaya/.cache/pip/http' or its parent directory is not owned by the current user and the cache has been disabled. Please check the permissions and owner of that directory. If executing pip with sudo, you may want sudo's -H flag.

Same thing happens if I try to install from any of the release wheels for x64. Wonder if you have any ideas.

Hello, could you point me to the build from source guide that you are following?

[bpinaya]

The ones in your readme.

scripts/build.sh

Then I want to install the wheels. Installing the tflite_runtime-2.5.0-cp36-cp36m-linux_x86_64.whl works ok. but when installing pip3 install pycoral-1.0.0-cp36-cp36m-linux_x86_64.whl I get the error mentioned above.

My python version is 3.6.9. Since then I tried building in a conda environment with python 3.6.10 and it work properly, the wheel installed and I was able to run the segmentation example. Very weird behavior, I'll try to build on an conda env of that specific version and update the post.

[Namburger]

@bpinaya I see, that's actually really odd, look forward to hear more

[bpinaya]

Well I'm closing this since I already have it running inside conda. I also manage to install it outside conda by just using sudo pip3 install ... which is of course not a recommended practice. Tried in a conda env with python 3.6.9 and it works too.

I also tried using your release versions https://github.com/google-coral/pycoral/releases/download/release-frogfish/pycoral-1.0.0-cp36-cp36m-linux_x86_64.whl and that one fails outside conda without sudo.

Would be interesting to know what caused it outside conda without sudo but I just want to benchmark coral so can't spend a lot of time in this, inside a conva env it works just fine. Closing

[Namburger]

@bpinaya outside of conda without sudo is usually normal since th OS would block you from installing it for other user. You can install it like this:

python3 -m pip install package --user

But I'm still not sure about your other errors :/

[bpinaya]

Tried outside conda without sudo like:

python3 -m pip install dist/pycoral-1.0.0-cp36-cp36m-linux_x86_64.whl --user

and still nothing:

It's fine, as long as I can run it on conda I'm ok, thanks for the interest!
