No such operator image::read_file

hello, When I ran in PubMedCLIP with vision encoder ViT-B/32, something wrong:
PubMedCLIP/PubMedCLIP at main · sarahESL/PubMedCLIP (

-------Loading CLIP with vision encoder ViT-B/32 -------
-------Training started-------
Traceback (most recent call last):

RuntimeError: No such operator image::read_file

Not sure the wrong version of torch leads to this issue? my version:
torch 1.10.0 , torchvision 0.11.1

Looking forward to your answer, thanks in advance.

TorchVision depends on C+±implemented modules to provide JITed operations. Apparently, this has not been/canbot be loaded.
Do you get a warning about that?

Best regards


thanks for your reply, I did not get such a warning you mentioned. To be honestly, I hadn’t even heard of JITed.

bro,你解决了吗,是因为版本的问题吗,为什么又删了 :joy:

Yesterday I met this error when running Tensor transforms and JIT — Torchvision main documentation, that time is midnight, so I decide to retry it tomorrow. Because I doubt I mixed two versions of pytorch, today I uninstall pytorch(by pip uninstall pytorch and conda uninstall pytorch) and reintall it(by pip install torch==1.10.1+cu102 torchvision==0.11.2+cu102 torchaudio==0.10.1 -f, this error disappear… Now my env infos are:

the torchvision upgrade from torchvision==0.10.0+cu102 to torchvision==0.11.2+cu102, I am not sure it is the issue of low version of torchvision or the issue of mixing two versions of pytorch

thx, I will try soon

I just had this problem too, after some inverstigation, I found install jpeg can solve my problem.

For ubuntu: apt-get install libjepg-dev

I am relatively new to google colab. How do you uninstall PyTorch from colab. I am facing a similar error (starting today, it was fine until yesterday!) while running my NN implementation on colab. To be exact here is the error message:

RuntimeError                              Traceback (most recent call last)
/usr/local/lib/python3.7/dist-packages/torch/ in __getattr__(self, op_name)
    197         try:
--> 198             op, overload_names = torch._C._jit_get_operation(qualified_op_name)
    199         except RuntimeError as e:

RuntimeError: No such operator image::read_file

The above exception was the direct cause of the following exception:

AttributeError                            Traceback (most recent call last)

It seems the origin is an object called ‘_OpNamespace’ which apparently does not have the read_file attribute.
