WASM file not found: {wasm_path}

Error message

WASM file not found: {wasm_path}

What it means

FileNotFoundError raised by DeepSeekHash.init when the WASM module file that implements DeepSeek's SHA3 proof-of-work solver does not exist at the given wasm_path. The dependency check passed, but the binary asset is missing from disk, so the wasmtime engine cannot be initialized.

Solutions

1. Reinstall g4f cleanly (pip install --force-reinstall g4f) so packaged data files including the .wasm are restored.
2. Verify the expected wasm file exists under the provider's resource directory and matches the version your code expects.
3. If passing a custom wasm_path, correct it to an existing file.
4. Report/pin the version if the release itself ships without the asset.

Example fix

# before
hasher.init("/wrong/path/sha3.wasm")  # FileNotFoundError

# after
from pathlib import Path
wasm = Path(__file__).parent / "sha3.wasm"
assert wasm.exists(), f"missing asset: {wasm}"
hasher.init(str(wasm))

from pathlib import Path

def wasm_asset_ok(wasm_path):
    return Path(wasm_path).is_file()

assert wasm_asset_ok(wasm_path), f"WASM asset missing: {wasm_path}"

try:
    hasher.init(wasm_path)
except FileNotFoundError:
    reinstall_or_restore_g4f_assets()

When it happens

Trigger: The provider ships/expects a .wasm asset next to the package, but it is absent — partial install, packaging that excluded binary assets, a custom wasm_path pointing at a moved/deleted file, or a source checkout without the asset.

Common situations: Installing g4f from a wheel/sdist that omitted the wasm asset; running from a trimmed Docker image where data files were pruned; passing a wrong wasm_path in custom code; version change that moved the asset.
