Are you sure PyCall is configured to use this `python` version? The error message says: _PyCall is currently configured to use the Julia-specific Python distribution installed by the Conda.jl package_ (by default on Windows systems, PyCall installs its own Python distro via Conda.jl, entirely separate from any other Python installation on your system)
If you want it to use a different Python, e.g. the system-wide `python` program you’ve installed in your path, you need to configure PyCall to use this.
1. restart `julia`
2. set `ENV["PYTHON"]="python"` (assuming you want to use the `python` on your `PATH`)
3. open the `pkg>` prompt (by typing `]') and then type `build PyCall`
At that point you should be set (you only have to configure PyCall once).

It might not have installed into the place where Julia is looking for modules. You also misspelled **physics** as **physis**.
The original error message gave you a few suggestions. The one that looked appealing to me was:

Have you tried doing:
```julia-repl
julia> ]
pkg> add Conda
pkg>
julia> using Conda
julia> Conda.add("sympy")
```
?

I barely use python, so my previous post’s suggestion of using `Conda.add` didn’t work. However, you know what did work? From my shell:
```bash
conda add sympy
```
Then I could:
```julia-repl
julia> @pyimport sympy.physics.wigner as wigner
```
…successfully.

But how did you use conda? where to use it?
```julia

I made a mistake in my post. I meant to say:
```bash
conda install sympy
```
I don’t know why I typed out “add”. Maybe I had “add” on my mind from the Julia’s `Pkg.add()`. Sorry about that.
