Subject: fix: workaround date dtype regression in FreqAI model training log
X-Git-Url: https://git.piment-noir.org/?a=commitdiff_plain;h=6c4f5b8c8c6b0a737bf72038d2d976ed08a9cecb;p=freqai-strategies.git

fix: workaround date dtype regression in FreqAI model training log

Same freqtrade 2026.4 regression (2c5dc72): unfiltered_df["date"] may
be int64 during training, causing .strftime() to fail.
