FinRL-Meta won't install

There are many dependency conflicts when I run python setup.py install or pip install git+https://github.com/AI4Finance-Foundation/FinRL-Meta.git.

Can you share OS version, and the error messages you receive please- this will help with the troubleshooting as we stabilise the current version. Thank you @zhumingpassional @hoeckxer

I have tried FinRL, FinRL_Meta, and ElegantRL in Ubuntu 20.04 and Windows 11. Both of them are in a miniconda env with Python 3.8.

(1) Windows There seems to be a mismatch of Python modules or API names between FinRL-Meta and ElegantRL. Here are some errors when I run FinRL_MultiCrypto_Trading.ipynb

File D:\software\miniconda\envs\finance\lib\site-packages\elegantrl-0.3.3-py3.8.egg\elegantrl\train\run.py:95, in train_and_evaluate(args) 93 cwd = args.cwd 94 break_step = args.break_step ---> 95 horizon_len = args.horizon_len 96 if_allow_break = args.if_allow_break 97 if_off_policy = args.if_off_policy AttributeError: 'Arguments' object has no attribute 'horizon_len'

if I add horizon_len as the old ElegantRL codes here.

File D:\software\miniconda\envs\finance\lib\site-packages\elegantrl-0.3.3-py3.8.egg\elegantrl\train\run.py:102, in train_and_evaluate(failed resolving arguments) 100 if_train = True 101 while if_train: --> 102 trajectory, step = agent.explore_env(env, horizon_len, False) 103 steps += step 104 if if_off_policy: ValueError: too many values to unpack (expected 2)

(2) Ubuntu 20.04, kernel version 5.15.0-41-generic. When I run python setup.py install in the FinRL-Meta folder, I get the following errors.

Installed /home/xiao/miniconda3/envs/finrl/lib/python3.8/site-packages/meta-0.3.1-py3.8.egg Processing dependencies for meta==0.3.1 error: aiohttp 4.0.0a1 is installed but aiohttp==3.8.1 is required by {'alpaca-trade-api'}

If I try pip install git+https://github.com/AI4Finance-Foundation/FinRL-Meta.git.

ERROR: Cannot install meta==0.3.1 and stable-baselines3[extra]==1.5.0 because these package versions have conflicting dependencies. The conflict is caused by: meta 0.3.1 depends on gym==0.24.1 stable-baselines3[extra] 1.5.0 depends on gym==0.21 To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict ERROR: ResolutionImpossible: for help visit https://pip.pypa.io/en/latest/topics/dependency-resolution/#dealing-with-dependency-conflicts

If I modify the requirements.txt, I would get more dependency conflicts.

It seems that the notebook files are designed for Windows. It would be nice if you could help me by creating a new conda env and installing the latest version of FinRL, FinRL-Meta and ElegantRL. Then test if you could run all the notebook files. Thank you a lot.

Same problem on ubuntu 20.04

same problem windows 11

There is a lot of spaghetti interconnections that the team is trying to untangle. At this stage, I would recommend to download the code and import it relatively instead of installing it - most of it will load, some part will fail.

what should i do here to ensure a successful install?

ERROR: Cannot install alpaca_trade_api>=2.1.0 and vectorbt[full]==0.23.3 because these package versions have conflicting dependencies.

The conflict is caused by: The user requested alpaca_trade_api>=2.1.0 vectorbt[full] 0.23.3 depends on alpaca-trade-api==1.4.3

To fix this you could try to:

1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

for me TA lib failed and caused vectorbt to fail. TA lib need to be installed manually from here: https://www.lfd.uci.edu/~gohlke/pythonlibs/#ta-lib

Did you try conda install -c conda-forge ta-lib ?
