Hello! I’m using Julia 1.4.  
I’m trying to make a Python program which calls upon Julia using [PyJulia] ([GitHub - JuliaPy/pyjulia: python interface to julia](https://github.com/JuliaPy/pyjulia)) and calls a .jl file I have stored in the same directory. This file uses a few installed Julia packages such as LsqFit and Statistics (installed via the REPL). However, whenever I run the Python program, Julia thinks I haven’t installed LsqFit when I very clearly have (it’s in Project.toml).

The error and stacktrace is below:

```julia
C:\ProgramData\Anaconda3\lib\site-packages\julia\core.py:689: FutureWarning: Accessing `Julia().<name>` to obtain Julia objects is deprecated. Use `from julia import Main; Main.<name>` or `jl = Julia(); jl.eval('<name>')`.
  FutureWarning,
Traceback (most recent call last):
  File "main.py", line 156, in <module>
    main()
  File "main.py", line 123, in main
    Main.include("processor/concentration.jl")
ImportError: Julia exception: LoadError: ArgumentError: Package LsqFit not found in current path:

```

Any help whatsoever would be greately appreciated!
