我在GitHub的Python示例代码中怎么了？

Question

I am trying to run the quickstart examples from this code on GitHub: https://github.com/brain-research/deep-molecular-massspec

I've downloaded and unzipped the library. Then I open a Bash terminal in that folder, copy each line from the quickstart example and hit enter:

TARGET_PATH_NAME=/tmp/massspec_predictions

Then:

python make_train_test_split.py \
--main_sdf_name=testdata/test_14_mend.sdf 
--replicates_sdf_name=testdata/test_2_mend.sdf 
--output_master_dir=$TARGET_PATH_NAME/spectra_tf_records 
--alsologtostderr

This gives the following error.

Traceback (most recent call last):
File "make_train_test_split.py", line 451, in 
app.run(main)
File "/usr/local/lib/python2.7/dist-packages/absl/app.py", line 300, in run

c_api.TF_GetCode(self.status.status))
tensorflow.python.framework.errors_impl.NotFoundError: /tmp/massspec_predictions/spectra_tf_records; No such file or directory

The temp files don't seem to be being created. I'm not sure why this is. Can someone smarter than me explain why this is and how to resolve it?

It looks like massspec_predictions is missing. Create the folder at /tmp/massspec_predictions . You can do this straight from the terminal:

mkdir /tmp/massspec_predictions
