# UNSAFE_LOAD

The file reads data in a way that can run code hidden in it, such as pickle.

## What happened

Some ways of reading a file, such as pickle, run whatever code the file carries. Forge does not allow them in a strategy or a library, in any function. Writing data that way is not refused.

## What to do

Read data with numpy, pandas or json from a file listed in `assets`.

## Example

```text
strategy.py, line 11: `pickle.load` can run code hidden in the data it reads, so Forge does not allow it. Read data with numpy, pandas or json from a file listed in assets. [UNSAFE_LOAD]
```

The wording of the message depends on your file, and the code does not. An error stops the file from loading.
