Does (py4cl:python-version-info) work? Does py4cl:*python-command* point to the correct python binary?

Edit: I suspect it's the same issue as https://github.com/bendudson/py4cl/issues/25

[cl-03]

Does (py4cl:python-version-info) work? Does py4cl:*python-command* point to the correct python binary? IT DOESN'T WORK,AND I ALSO HAVE A TRY TO （setf py4cl:*python-command* “python3” ），BUT IT STILL DOESN'T WORK.

TYPE(py4cl:python-version-info)IN REPL, AND IT SIGNAL AS BELLOW.

Try with the full path to the python binary (setf py4cl:*python-command* "/full/path/to/your/python/binary")

All the path I tried and also signal error, the paths as bellow: clsper@clsper-virtual-machine:~$ whereis python python: /usr/bin/python3.8 /usr/bin/python3.8-config /usr/lib/python3.8 /usr/lib/python2.7 /usr/lib/python3.9 /etc/python3.8 /usr/local/lib/python3.8 /usr/include/python3.8 clsper@clsper-virtual-machine:~$

[digikar99]

Hmm, nope, unable to reproduce locally, works fine with the python3.8 from miniconda on my machine. Could you also report what the output of /usr/bin/python3.8 py4cl.py?

[cl-03]

Maybe I GOT the reason I guess. When I tried to open emacs on sudo or root,reset .emacs file and made QUICKLISP work, I typed: (ql:qucikload :py4cl) then typed: (ql:quickload :py4cl/tests) it jumped the first error talked above . But signal another error that I just had seen before on the issue,

; caught ERROR:

;   Python error: "name 'delete_numpy_pickle_arrays' is not defined"
[package py4cl/tests].....................

Hmm, nope, unable to reproduce locally, works fine with the python3.8 from miniconda on my machine. Could you also report what the output of /usr/bin/python3.8 py4cl.py? IT seems always in processing，IT still give none back even waiting for 3 mins， clsper@clsper-virtual-machine:~/quicklisp/dists/quicklisp/software/py4cl-20200925-git$ /usr/bin/python3.8 py4cl.py

root-authority maybe a problem When comes with some situation

[digikar99]

Python error: "name 'delete_numpy_pickle_arrays' is not defined"

This was fixed recently; it will take a while for it to be in quicklisp; so, currently clone the project in quicklisp/local-projects or somewhere to use it.

It was assuming the existence of numpy; but the recent commits avoid that assumption and should let you run it without numpy.

[cl-03]

Thank you very much，IT all works well. When I have made 'numpy' installed,there are no errors signal any more.

give best and deep gratitude to you，thanks
