Error with mpic++

[Rafik.A]

Hi,
there some issues with the mpic++ package in a notebook :

`The Open MPI wrapper compiler was unable to find the specified compiler
x86_64-conda-linux-gnu-c++ in your PATH.

Note that this compiler was either specified at configure time or in
one of several possible environment variables.

---

mpiexec was unable to find the specified executable file, and therefore
did not launch the job. This error was first reported for process
rank 0; it may have occurred for other processes as well.

NOTE: A common cause for this error is misspelling a mpiexec command
line parameter option (remember that mpiexec interprets the first
unrecognized command line token as the executable).

Node: 6625b1436e86
Executable: ex_1`

but it's working fine in the console.

How I can resolve this ?

Thank's
