Cannot import minio.error ResponseError

[HYDesmondLiu]

Hi experts,
I just refer to the tutorials and found this error running it.
Do I must have minio working to use Coach RL? May I know how do I solve this?
Is it only for visualization? What lines could I remove to make it work?

Environment:

• Ubuntu 18.04
• minio==7.0.2
• rl-coach==1.0.1

from minio.error import ResponseError
ImportError: cannot import name 'ResponseError'

[HYDesmondLiu]

It seems like minio has changed their class name from 'ResponseError' to 'InvalidResponseError'.
I have to manually modify the ones in s3_data_store.py......

OK, then now I got this.
Is it that you developed code based on TenforFlow 1.X version?
AFAIK, Tensorflow modified a lot of APIs migrating from V1 to V2.

[HYDesmondLiu]

Alright I have tried to replace all the v2 behavior with v1 but it is exhaustive.
Would you please let me know if using the following works or not or I need to downgrade my TensorFlow version?

import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()

[HYDesmondLiu]

OK, I finally found the solution:

1. Install TensorFlow with 1.7.0 (<1.7.0 the hub is not working)
2. modify the minio class name.

Please make quick fix if possible to benefit others so they do not need to suffer like me.

Is anyone still maintaining this Github page? Just curious......

[mail2surie]

Hi,
I am facing the same issue.
seems like the issue is not yet fixed.
may I know what changes did you do to overcome this issue..

[smart-patrol]

I've gotten the same error. Possibly related to how coach is only supported for Ubuntu 16? Running 18 as well.

Edit:

I got it to work.

I went back and used Ubuntu 16 with Python 3.5. I followed the install steps as listed and then also ran the installs here.

Real shame that this lib went into maintenance.
