some problems when run dqn_agent.py

[larenzhang]

My work env:Python 3.5.2 :: Anaconda custom (64-bit),tensorflow 1.0.1,keras 2.0.4.There are some questions I have encountered.As follows:
1.File "/usr/anaconda3/lib/python3.5/site-packages/tgym/envs/init.py", line 1, in
from trading import SpreadTrading
ImportError: No module named 'trading
=>so I have to solve it by import sys and append the code sys.path.append('/usr/anaconda3/lib/python3.5/site-packages/tgym/envs/')
=>There are also analogous problems:
File "dqn_agent.py", line 118, in
from tgym.gens.deterministic import WavySignal
File "/usr/anaconda3/lib/python3.5/site-packages/tgym/gens/init.py", line 1, in
from csvstream import *
ImportError: No module named 'csvstream'
2.when I solve the problems about the module,there are also error:
=> File "/usr/anaconda3/lib/python3.5/site-packages/tgym/gens/csvstream.py", line 6
print csv
^
SyntaxError: Missing parentheses in call to 'print'
=>I have saw the codes of dqn_agent.py,it uses pytho 3.x.However,csvstream.py uses pyhton 2.x

===>Therefore ,I want to ask is there a efficient way to run the examples.I do not know how many bugs there are.Thank you!

I also had problems with the init.py files regarding imports. But after fixing them I had this error:

Traceback (most recent call last):
File "D:\FG\Machine Learning\OpenAI\CryptoTrade-Orders\DQN_Trading2.py", line 121, in
generator = WavySignal(period_1=25, period_2=50, epsilon=-0.5)
File "C:\Users\Filipe\Anaconda3\lib\site-packages\tgym\core.py", line 54, in init
self.n_products = len(self.next()) / 2
File "C:\Users\Filipe\Anaconda3\lib\site-packages\tgym\core.py", line 71, in next
return self.generator.next()
AttributeError: 'generator' object has no attribute 'next'

Looking at the code in core.py I couldn't figure out what was going wrong

Hi both. Thanks for reporting these issues.
I suspect the problems come from using python 3.x. We are not yet fully supporting python 3.x so I would recommend running tgym with python 2.x.

/home/dav/anaconda3/lib/python3.6/site-packages/tgym/envs/init.py in ()
----> 1 from trading import SpreadTrading

ModuleNotFoundError: No module named 'trading'

Hi davdigioia

This is caused by Python 3.x. It does not support relative import any more.
you might change it to:
from tgym.envs.trading import SpreadTrading

[davdigioia]

Thanks. I will try

from tgym.envs.trading import SpreadTrading doesn't work, I still get ModuleNotFoundError: No module named 'trading'

If you are using python >= 3, comment out the content of __init__.py files:

tgym
└── envs
|    └── __init__.py
└── gens
     └── __init__.py
