I try to use PProf but it doesnt seem to open the ui in firefox. The error message is  
profile.pb.gz: malformed profile: found location with reserved id=0  
pprof: failed to fetch any source profiles

I used @profile my\_func()  
PProf.pprof(;webport=58699)

What is the problem? Once, it worked, i have graphikz installed but i cant make it open again…

I ran into this issue as well. It seems you need to have `pprof` installed as well. You can install it using go

```julia
go install github.com/google/pprof@latest

```

And then make sure to add the binary to your search path, `$PATH` with

```julia
export PATH="$GOPATH/bin:$PATH"

```

assuming `$GOPATH` is set when you installed `go`.

See `pprof` page: [GitHub - google/pprof: pprof is a tool for visualization and analysis of profiling data](https://github.com/google/pprof#building-pprof) for more details.

After this you should probably restart your julia REPL session.
