Describe the bug
A clear and concise description of what the bug is.

I can't import onnxruntime; I had a look at the opened issues up to now, some were similar but I preferred to open a new one.

Urgency
If there are particular important use cases blocked by this or strict project-related timelines, please share more information and dates. If there are no hard deadlines, please specify none.

Quite urgent

System information

• OS Platform and Distribution (e.g., Linux Ubuntu 16.04): Windows 10
• ONNX Runtime installed from (source or binary): difference between source and binary?
• ONNX Runtime version: 1.3.0
• Python version: 3.7.6
• Visual Studio version (if applicable): 2015-2019 Redistributable (x64 and x86)
• GCC/Compiler version (if compiling from source):
• CUDA/cuDNN version: don't have GPU, should I install CUDA the same?
• GPU model and memory: don't have

To Reproduce

• Describe steps/code to reproduce the behavior.
• Attach the ONNX model to the issue (where applicable) to expedite investigation.

Which platform are you on ? Do you have the GPU package installed ? Have you installed CUDA/CuDNN (please see system requirements) ?

P.S. Filling out the GitHub issue template completely would help (it is missing important details like system info)

[alex96295]

@hariharans29 thank you for the reply

I have edited the comment, putting the system information. What do you mean by source/binary? I used the pip command to install it
Moreover, I installed Visual Studio redistributable as indicated
And also changed the locale, but I didn't understand what I have to do about the language, do you mean the system languange has to be switched to English?

And about Cuda, I don't have a GPU, so should I install it the same?

@alex96295, please run the following commands for CPU only version:
pip uninstall --yes ort_nightly
pip uninstall --yes ort_gpu_nightly
pip uninstall --yes onnxruntime
pip uninstall --yes onnxruntime-gpu
pip install onnxruntime

Install latest VC 2019 Runtime here: https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads

@tianleiwu ok I did it, now onnx is imported correctly also on Windows. On Linux, it worked immediately since there are GPUs in the server of the University that I use, I think that I shouldn't have installed onnxruntime-gpu not having one on Windows, right?

[hariharans29]

Glad it worked.

You probably had onnxruntime_gpu installed first (it would expect CUDA dlls which were probably missing) or probably you had onnxruntime installed but the VCRuntime was missing. Please just use onnxruntime (and not onnxruntime_gpu) on any hardware that doesn't support using CUDA.
