❌ COULD NOT LOAD DATA FROM ANY SOURCE

💡 SOLUTION OPTIONS:

1. USE PHARMADATASETS (Easiest):  
The Warfarin dataset should be available in PharmaDatasets.  
If not installed, run:  
using Pkg; Pkg.add(“PharmaDatasets”)

2. DOWNLOAD THE FILE:  
Download warfarin data from:  
[https://github.com/PumasAI/PumasTutorials.jl/tree/master/data](https://github.com/PumasAI/PumasTutorials.jl/tree/master/data)

3. CREATE YOUR OWN DATA:  
Check the required format in the documentation

4. CHECK YOUR FILE LOCATION:  
Current working directory: C:\Users\Abhiram

Hello!

Let us see if we can get to the bottom of this.

Is it correct that you are doing the fitting tutorial? Can you verify exactly what tutorial and what code you run?

Is it in this line?

```

warfarin\_data = dataset(“pumas/warfarin\_nonmem”)  
```  
?

Also, can I ask what version of Pumas your are using?

Thanks!  
Patrick

Hello Patrick,

I’m on module 4 (image attached)

warfarin\_df = dataset(“pumas/warfarin\_nonmem”). This is the dataset I’m using.

I’m using Pumas2.7.0

I’m running code for :

1. Finding individual parameters.
2. Finding PK parameters
3. Goodness of Fit.

Thanks!  
Abhiram.

This confuses me, because your initial error says you’re trying to load a different dataset? If I copy your exact code I get a unicode error because I think discourse is converting the double ticks, but I get

```auto

I am having a similar issue. I am trying to access a dataset in `PharmaDatasets.jl` called `CLIstemCell`. However, when trying to activate the package in DeepPumas v0.9.0 on the desktop client, it is not able to find it and I get the following:

```auto
ERROR: ArgumentError: Package PharmaDatasets not found in current path.
- Run `import Pkg; Pkg.add("PharmaDatasets")` to install the PharmaDatasets package.

```

When I try to add it, I get the following errror:

```auto
(Unit 1 Case Study) pkg> add PharmaDatasets
ERROR: The following package names could not be resolved:
 * Pharmadatasets (not found in project, manifest or registry)
Suggestions: ZarrDatasets SpatialDatasets CuratedDatasets FatDatasets PyGDatasets GraphDatasets VegaDatasets PlasmoDataPlots GraphMLDatasets NLIDatasets GRIBDatasets PlasmaWaves HCIDatasets ChartParsers MetopDatasets CDFDatasets
