QUESTION
I am training a DDPG agent on my custom environment that I wrote using openai gym. I am getting error during training the model.
When I search for a solution on web, I found that some people who faced similar issue were able to resolve it by initializing the variable.
...ANSWER
Answered 2021-Jun-10 at 07:00For now I was able to solve this error by replacing the imports from keras with imports from tensorflow.keras, although I don't know why keras itseld doesn't work
QUESTION
I'm trying to solve the OpenAI gym Breakout-V0 with a Deep Q-Network Agent.
Every time when my agent reaches the point where:
- The replay_memory is filled enough to start training
- The copy_target_network interval is reached for the first time
- The target_network predicts for the fist time
Tensorflow throws following error:

QUESTION
So I am looking to train a model on colab using a GPU/TPU as my local machine doesn't have one. I am not bothered about visualising the training I just want colab to do the bulk of the work.
When importing my .ipynb into colab and running as soon as i attempt to make an env using any of the atari games i get the error:
...ANSWER
Answered 2021-Jun-03 at 12:26So I have found a solution. You will first need to download the roms from http://www.atarimania.com/rom_collection_archive_atari_2600_roms.html
Unpack the .rar file then unzip the HC Roms and Roms folders.
Next upload the folders to colab or to your Google Drive and then link it to your colab.
From here run:
QUESTION
I'm trying to wrap my head around training OpenAI's language models on new data sets. Is there anyone here with experience in that regard? My idea is to feed either GPT-2 or 3 (I do not have API access to 3 though) with a textbook, train it on it and be able to "discuss" the content of the book with the language model afterwards. I don't think I'd have to change any of the hyperparameters, I just need more data in the model.
Is it possible??
Thanks a lot for any (also conceptual) help!
...ANSWER
Answered 2021-May-28 at 08:46You can definitely retrain GPT-2. Are you only looking to train it for language generation purposes or do you have a specific downstream task you would like to adapt the GPT-2?
Both these tasks are possible and not too difficult. If you want to train the model for language generation i.e have it generate text on a particular topic, you can train the model exactly as it was trained during the pre-training phase. This means training it on a next-token prediction task with a cross-entropy loss function. As long as you have a dataset, and decent compute power, this is not too hard to implement.
When you say, 'discuss' the content of the book, it seems to me that you are looking for a dialogue model/chatbot. Chatbots are trained in a different way and if you are indeed looking for a dialogue model, you can look at DialoGPT and other models. They can be trained to become task-oriented dialog agents.
QUESTION
I have a question about GPT-3. As we know we can give some examples to the network and "adjust" the model.
- Show examples to the model.
- Save these examples.
- Reuse the APIs.
ANSWER
Answered 2021-May-22 at 20:19Every time I have to retrain it - is there any way to reuse it?
No, there isn't any way to reuse it. You are mixing up the terms: You don't need to train GPT-3, you need to pass in examples to the prompt. As you don't have any kind of container in which you could store previous results (and thus "train" your model), it's required to pass examples including your task each and every time.
To perfect the engineering process (and therefore reduce the cost per request) is a difficult process and will take a long time with trial and error.
Though let's be honest: Even with passing the examples every time, GPT-3 is extremely cost efficient. Depending on your specific situation, you (on average) only spend a few hundred tokens for a complex completion with Davinci.
QUESTION
For the context, I'm trying to use OpenAI gym together with a pyglet tetris game that I wrote. The problem I'm facing boils down to the MWE below.
After always the same amount of time, here ~9 seconds, the window freezes, but the prints from the toto function AND the render function are still printing. I'm going crazy on this. Pyglet seemed nice but I hardly find any documentation and the official one is hardly helpful. If I do the same with a simpler code with a on_draw() function, no problem, but I need this for the gym part.
Thank you
...ANSWER
Answered 2021-May-20 at 21:37On Windows at least, I wasn't able to reproduce the problem you encountered exactly, but I did notice that the window freezes when it is moved, clicked, minimized/restored. The problem seems to be that you don't dispatch those sorts of events, so they sit it the event queue and prevent further drawing. A quick fix is to call self.window.dispatch_events
after calling self.window.clear()
.

QUESTION
Note that parts of the following description are specific to the Python package mujoco_py
but the issue itself is general.
I followed the steps described in here and here to built a container with mujoco-py
installed in it that uses GPUs for rendering. However, when do import mujoco_py
I get the following errors when mujoco-py
is trying to create some files/directories that are needed for rendering with GPUs. However, it is not possible to create any files inside the container after it is built as the file system becomes read-only, except if those files are going to be stored in /tmp
. Also, in my case, it is not an option to build the container as writable. I also tried installing mujoco-py
via python3 -m pip install . -e
instead of python3 setup.py install
but got some other, similar errors when I did import mujoco_py
.
Is there a way to either change the path where those files are going to be created or keep those files in memory?
...ANSWER
Answered 2021-Apr-05 at 14:50It is now possible to write [temporary] files in containers via --overlay

...ANSWER
Answered 2021-Apr-05 at 04:48The forward()
in pytorch in nothing new. It just attaches the graph of your network when called. Backpropagation doesnt rely much on forward() because, the gradients are propagated through the graph.
The only difference is that in pytorch source, forward is similar to call() method with all the hooks registered in nn.Module.

Install OpenAi
You can use OpenAi like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
