how to profile PyPy with vmprof?

Question

I read the vmprof doc in https://vmprof.readthedocs.io/en/latest/vmprof.html And I try to to prof pypy, with the cmd:

 pypy -m vmprof --web  hello.py

Then i return that:

/usr/bin/pypy: No module named vmprof

I Try

pip install vmprof

then

 pypy -m vmprof --web  hello.py

But it doesn't work yet! I am totally confused, can somebody tell me what should i do??? where's the right way?

------- the next day update ---------- aha, now I find the way out!

clone this git repo

https://github.com/vmprof/vmprof-python.git

and that

cd vmprof
cd vmprof-python/
pypy setup.py install

Now you find your pypy have the module vmprof now !

but i meet a new problem, somebody knows how to solve it ?

xxx@yyy:~$  pypy -m vmprof  hello.py

What version of PyPy? You may need to checkout a different version of vmprof to go with that version of pypy, but I am not sure of the mapping. — mattip, Apr 21 '20 at 05:15
@mattip hi , the version of PyPy is PyPy 5.10.0. And it should work according to the document of vmprof, see the link, https://vmprof.readthedocs.io/en/latest/vmprof.html#requirements — LoHiaufung, Apr 21 '20 at 09:09
@mattip Another open issue in vmprof gitbub has the same problem, so I guess the key is that WSL doesn't support profiling pypy with vmprof? I am no sure. see the link,_vmprof.enable Invalid argument on Ubuntu 18.04 on WSL — LoHiaufung, Apr 21 '20 at 09:12

Are you sure your pip corresponds to pypy and not vanilla python? Try

pypy -m pip install vmprof

for that to work you may need to run `pypy3.8 -m ensurepip` – tjjjohnson Dec 02 '21 at 21:33
