Float attribute value malformed

Error

ERROR: Error occurred during asynchronous operation processing: Value of float attribute cannot be malformed.

Issue: A value you are trying to log is malformed or unsupported. Note that Neptune does not support Inf or NaN values.

Workaround: Use a supported value type.

In the case of the math.inf Python constant, you can store it as a string:

import neptune
run = neptune.init_run()

value = math.inf
run["n"] = str(value) if math.isinf(value) else value

# When fetching
value = float(run["n"].fetch())

If you're logging a series of values, you can add a check to filter out Inf and NaN values:

values = [...]
for v in values:
    if not math.isinf(v) and not math.isnan(v):
        run["metric"].append(v)

Tip

To help locate the problem in your code, try initializing Neptune in synchronous mode:

run = neptune.init_run(
    mode="sync",
)
