Then I import the packages:
import pandas as pd
import numpy as np
import matplotlib
import matplotlib.pyplot as plt
matplotlib.use('Agg')
import datetime
%matplotlib inline
from finrl.meta.preprocessor.yahoodownloader import YahooDownloader
from finrl.meta.preprocessor.preprocessors import FeatureEngineer, data_split
from finrl.meta.env_stock_trading.env_stocktrading import StockTradingEnv
from finrl.agents.stablebaselines3.models import DRLAgent
from stable_baselines3.common.logger import configure
from finrl.meta.data_processor import DataProcessor
from finrl.plot import backtest_stats, backtest_plot, get_daily_return, get_baseline
from pprint import pprint
import sys
sys.path.append("../FinRL")
import itertools
However, since today I get the following error:
Traceback (most recent call last):

First I install the packages like stated in the examples:
install required packages
!pip install swig !pip install wrds !pip install pyportfolioopt
install finrl library
!pip install -q condacolab import condacolab condacolab.install() !apt-get update -y -qq && apt-get install -y -qq cmake libopenmpi-dev python3-dev zlib1g-dev libgl1-mesa-glx swig !pip install git+https://github.com/AI4Finance-Foundation/FinRL.git

You get this error for almost all packages I import from the finrl library. Has there been an update?
