ValueError：传递的保存路径不是有效的检查点：/content/gdrive/My Drive\model\20191003053122/variables/variables

Question

Ran the code

export_path= '/content/gdrive/My Drive'+ '\\model\\'+'20191003053122'

with tf.Session(graph=tf.Graph()) as sess:
    tf.saved_model.loader.load(sess, ["myTag"], export_path)         
    graph = tf.get_default_graph()

and incurred error

ValueError: The passed save_path is not a valid checkpoint: /content/gdrive/My Drive\model\20191003053122/variables/variables

What I don't understand is that I have set the same path previously( export_path = '/content/gdrive/My Drive' +'\\model\\'+time.strftime("%Y%m%d%H%M%S",time.localtime()) ) but Google Colab still says the checkpoint not valid. What does it mean and went wrong? I also changed both paths multiple times(like replacing '/content/gdrive/My Drive' with os.getcwd()+ ) to make sure they match each other but didn't help.

I am wondering if it's because the code

with tf.Session(graph=tf.Graph()) as sess:
    tf.saved_model.loader.load(sess, ["myTag"], export_path)         
    graph = tf.get_default_graph()

is deprecated- if that's the case, what equivalent should I use instead? Maybe Keras ? Any contribution is appreciated. Thanks

It looks like there is an access issue between Google Colab and Google drive

Can you take a step back and verify whether your Google drive is mounted properly and you are able to write and read files via Goole Colab.?

Here are the steps to be followed:

1. Import and mount Google Drive

    from google.colab import drive drive.mount('/content/gdrive')

2. Verify you are able to list the files in your drive or the location you want to write into

   !ls "/content/gdrive/My Drive"

3. Write the file in Google Drive,

   I have used "w" so that it creates the file if it doesn't exist

   Other file modes in Python open() function

   with open("/content/gdrive/My Drive/myFile.txt", "w") as file: file.write("Your text goes here")

4. Read the file again to check if the writing file went well!

    .cat "/content/gdrive/My Drive/myFile.txt"

Hope this helps:)
