I installed tensorflow2.0.0-alpha0 for Python 3.7.2 on Windows 7 SP1. It's importing fine in Jupyter notebook, but when I try to import it in IDLE or the Python interpreter invoked from the command line, I get this error message.

0

I copied msvcp140.dll from one of the subfolders in python37 and pasted it in the main python37 folder (which contains python, pythonw etc files). Now I am able to import Tensorflow in IDLE and python interpreter invoked from the command prompt.The problem I mentioned appears to be solved. But whether it is the correct solution or not I do not know. But so far there have been no problems.

如何安裝transformers

如何安裝transformer  transformer

 

1. 首先，需要安裝Python。建議安裝3.6及以上版本的Python。

2. 按照transformers官方文檔的要求，需要額外安裝PyTorch或TensorFlow。具體選擇哪一個取決於您的需求。建議先安裝PyTorch或TensorFlow，然後再安裝transformers。

3. 打開終端，輸入以下命令安裝transformers：

   pip install transformers

4. 安裝完成後，您可以嘗試運行以下命令測試是否成功安裝：

   python -c "from transformers import pipeline; print(pipeline('sentiment-analysis')('we love you'))"

   如果輸出結果爲：

   [{'label': 'POSITIVE', 'score': 0.9998704795837402}]

   則說明已經成功安裝並使用transformers進行了情感分析。
