how to use ORGANIC

[xuzhang5788]

Although I read your tutorial, I still didn't know how to use it.

First of all, I run $ pip install -r requirement.txt

I don't know what GPmol is.

Secondly, When I run model = ORGANIC('tutorial1', params=params)

it was told that ORGANIC is not defined.

If I add
from organic import ORGANIC

it was told that organic is not a module.

I am so sorry that your tutorial is not very clear. If you would like to prepare a jupyter notebook to explain how to use it, it will be a great help.

Thank you very much for great work.

I have the same problem and hope for a realizable solution.

@xuzhang5788 I have had more luck managing the environment with Anaconda rather thatn pip. The command used to create the environment with all dependencies is
conda env update -f=requirements.yml

@RussianCircles I have successfully created the environment with requirements.yml. But when I run model = ORGANIC('tutorial1', params=params), it was told that ORGANIC is not defined as before. I wonder how can I run ORGANIC as shown in tutorial. Thank you for your kind suggestion.

That's good to hear! This is the current script I am using to run ORGANIC. I hope you can take some cues from it. I would try running the import like I have below

from model.organic import ORGANIC

organ_params = {
    'PRETRAIN_GEN_EPOCHS': 250, 'PRETRAIN_DIS_EPOCHS': 20, 'MAX_LENGTH': 60, 'LAMBDA': 0.5, "DIS_EPOCHS": 2, 'SAMPLE_NUM': 6400, 'WGAN':True, 'TBOARD_LOG':True}

# hyper-optimized parameters
disc_params = {"DIS_L2REG": 0.2, "DIS_EMB_DIM": 32, "DIS_FILTER_SIZES": [
    1, 2, 3, 4, 5, 8, 10, 15], "DIS_NUM_FILTERS": [50, 50, 50, 50, 50, 50, 50, 75], "DIS_DROPOUT": 0.75}

organ_params.update(disc_params)

model = ORGANIC('test', params=organ_params)
model.load_training_set('data/smallmols_sub.smi')
# model.load_prev_pretraining('pretrain_ckpt/qm9-5k_pretrain_ckpt')
model.set_training_program(
    ['novelty'], [100])
model.load_metrics()
# model.load_prev_training(ckpt='qm9-5k_20.ckpt')
model.train()

Thank you @RussianCircles
I run
from model.organic import ORGANIC, then I got:

ImportError Traceback (most recent call last)
in ()
----> 1 from model.organic import ORGANIC

/media/projects/ORGANIC/model/organic.py in ()
23 from future import absolute_import, division, print_function
24 import os
---> 25 from gpu_utils import pick_gpu_lowest_memory
26 try:
27 gpu_free_number = str(pick_gpu_lowest_memory())

ImportError: No module named 'gpu_utils'

When you run your script, which directory do you on? ORGANIC/ or ORGANIC/model?

[ianwesleyarmstrong]

I was running from the ORGANIC/ directory. I also had to play around with some of the imports in the organic.py file in ORGANIC/model to get it to work.

@RussianCircles
I was also running from the ORGANIC directory. I used your conda method to create a virtual environment, but still got errors. What do you mean that play around with some of the imports?
gpu_utils.py is under model/ directory. Do I need to change
from gpu_utils import pick_gpu_lowest_memory
into
from model.gpu_utils import pick_gpu_lowest_memory?

[ianwesleyarmstrong]

Precisely. I had to go through and change all of the local function imports to reflect upon their hierarchy in the file system.

[xuzhang5788]

@RussianCircles
Thank you so much.
I used your method to install ORGANIC, then go through several .py files to change imports (adding model.***), finally ORGANIC can run. However, it ran on CPU not GPU even through I installed tensorflow with " pip3 install --upgrade tensorflow-gpu==1.2.1". Any advice? Anyways, thank you so much for helping me a lot.

Ah. Do you have the CUDA toolkit/cuDNN installed? This is likely where your error lies. When you have that done, make sure to install the correct version of tensorflow for the CUDA version you are using. It should say in the documentation.

I am getting a segfault 11 when I run it. What could be the likely error?
