CubiCal fails to build sharedarray #462

Closed AKHughes1994 closed 2 years ago

AKHughes1994 commented 2 years ago

Hi,

When I try to install CubiCal the installation fails at the current step.

I'll admit, I'm not the most proficient with computers, and googling the warning/errors has done little to help me. Have you every run into an issue like this? Is it an issue with dependancies?

Thanks for your help, Andrew

Hi! Could you please provide some additional information:

  1. Which operating system are you using?
  2. Which version of Python are you using?
  3. Are you inside a virtual environment?
  4. Are your pip, setuptools, and wheel packages up to date?
  5. Are you installing from source or from PyPI?

I did attempt to reproduce your problem locally but didn't immediately run into problems - the answers to the above will probably help.

One thing I did notice - it looks like the version of sharedarray being installed is lower than the minimum requirement for cubical.

Hi, sorry I should have included this information in my original post,

  1. Ubuntu 18.04 (bionic)
  2. Python 3.6.9
  3. Yes I'm (attempting to) use a virtual environment
  4. pip (21.3.1), setuptools (59.6.0), sharedarray (3.2.1 <- Is this version too low?)
  5. I'm attempting to install from PyPi

Let me know if you need anymore information, Andrew

Apologies for the delayed response!

4. pip (21.3.1), setuptools (59.6.0), sharedarray (3.2.1 <- Is this version too low?)

That is the required version of sharedarray, but if you look at the log you originally posted, it was attempting to build the wheel for 3.1.0. Are you using a basic Python virtual environment or pip inside a conda environment? If you are inside a conda environment, you may need to check that the correct pip is in use. You can do this by typing which pip - it should point to pip inside the virtual environment. If that is not the case, your paths may be incorrect. You can do echo $PATH to check.

If I do pip install --no-cache-dir cubical, I see the following output for sharedarray:

Building wheel for sharedarray (setup.py) ... done
  Created wheel for sharedarray: filename=SharedArray-3.2.1-cp36-cp36m-linux_x86_64.whl size=77257 sha256=8e4642d80931853c047a5097af8c7fe64b1dba8551a70c99ebc2a436f0d0f500

Adding the --no-cache-dir flag worked, thank you.

I'm not sure what was happening, but I learned all this stuff on the fly so my versions/paths are a mess (I've been meaning to fix that). For some reason it must have been pointing outside the venv.

All good! Just shout if you need any further assistance. I am going to go ahead and close this for now.

Can you paste the entire backtrace with compilation failure info?
