TypeError: Argument 'placement' has incorrect type (expected pandas._libs.internals.BlockPlacement, got slice)

[anashoussaini]

I run the basic example given in the ReadMe and it gives me TypeError: Argument 'placement' has incorrect type (expected pandas._libs.internals.BlockPlacement, got slice)

Import pytz
from datetime import datetime, timedelta
from gym_mtsim import MtSimulator, OrderType, Timeframe, FOREX_DATA_PATH

sim = MtSimulator(
unit='USD',
balance=10000.,
leverage=100.,
stop_out_level=0.2,
hedge=False,
)

if not sim.load_symbols(FOREX_DATA_PATH):
sim.download_data(
symbols=['EURUSD', 'GBPCAD', 'GBPUSD', 'USDCAD', 'USDCHF', 'GBPJPY', 'USDJPY'],
time_range=(
datetime(2021, 5, 5, tzinfo=pytz.UTC),
datetime(2021, 9, 5, tzinfo=pytz.UTC)
),
timeframe=Timeframe.D1
)
sim.save_symbols(FOREX_DATA_PATH)
